My full name is John Tsatsaragos. I think that is necessary to present myself first.
WHO I AM
John Tsatsaragos lives in Volos area, Central east Greece.
He has a degree in Electronics and works in the production department of a large cement factory for over twenty-six years.
He has also worked as electronics engineer for Greek National Radio-Television.
His interests and job experience include all sound systems, constructing complex electronic circuits, transmitting and receiving radio signals, measuring all physical amounts including measures in the electromagnetic field, automation systems, computer systems, and basic computer programming.
He loves Physics and Astronomy and is also a member of the amateur Astronomy group in Volos.
He has designed, and has constructed, a station of observing and recording electrical pre-earthquake signals from the ground, which is in operation for more than 21 years. His recent installation is fully computerised.
Recently, he is member of a scientific team that works on Earthquake prediction based on electrical signals recorded on ground surface. The team apply an integrated methodology answering on "WHERE", "WHEN" and "OF WHAT MAGNITUDE" a large EQ will occur.
You can find full presentation of the team HERE.
You know already what I presented in topic 9. I will continue to present you my work and the teamwork here. I will use simple words and daily updated graphs.
For absolutely scientific presentation you can visit HERE.
Please feel free and comfortable here. Feel me as good friend from the opposite side of earth. I will answer on any question you have. I will explain anything you need to know on my research too.

HOW WE CAN SEE AN ONCOMING EQ IN GREECE?
From now on, you will be able to see the graph of the recent signals here. They are recorded in my station at Volos. This graph, titled RECENT 24-HOUR SIGNALS, will be updated almost every day. Thus, each time you will visit here, you will see the updated graph. (The dates appear on the horizontal axis).
In order to understand what exactly you see, I give you first the 40-day graph, which shows the corresponding signals for the big EQ in Skyros Island area in the Aegean Sea (M=6.4R), on 26th July 2001, at a distance 125 Km from my station.
PRE-EARTHQUAKE 24-HOUR SIGNALS OF SKYROS EQ
The second 40-day graph (below) shows the corresponding signals for the big EQ in Dodecanese Islands in the southeast Aegean Sea (M=6.3R), on 22nd January 2002, at a distance 545 Km from my station. The same graph shows also the corresponding signals for the big EQ in Afyon, province of Turkey, (M=6.5R), on 3rd February 2002, at a distance 722 Km east of my station.
PRE-EARTHQUAKE 24-HOUR SIGNALS OF DODECANESE ISLANDS AND AFYON, TURKEY EQ's
Finally, here is the 40-day graph of my recent signals.
RECENT 24-HOUR SIGNALS (Updated daily)
Notes:
First, the importance is the amplitude of the oscillation (yellow line). When the amplitude rises, an EQ is expected. As amplitude is bigger, more secure is that an EQ will occur.
Second, The three graphs above, have exact the same scale in both axes, for easy correlation.
I present you the bar graph below for more easy correlation between max amplitude of my signals before the big EQ's of Skyros Island, Dodecanese Islands, and Afyon Province (in Turkey), together with the amplitude of my last 24 hours signals. This graph is also updated almost every day.
ATTENTION
THE AMPLITUDE OF MY RECENT SIGNALS DOES NOT REPRESENTS MAGNITUDE OF AN ONCOMING EQ, BECAUSE THE DISTANCE OF ITS SOURCE IS UNKNOWN.
Complete description for each one of the above big EQ's including theory and examples of smaller EQ's, you can find in my site, which is:

HOW WE CAN FIND WHEN WILL BECOME THE ONCOMING EQ
When we see big amplitude signals we know that the oncoming EQ will occur in a few days.
We find that big EQ's became at the higher or lower peak of the mean daily tidal gravity variations curve, plus or minus one day. This is true for more than 90% of the big EQ's, which they occurred in Greece since the year 1952. So, we have to see when is the next three-day dangerous time window. The three last big EQ's around my station they occurred during this dangerous time window as well.
Tidal gravity curve is available for any place and time by a scientific computer program that gives a prediction curve. So, we can easily find when is the dangerous three-days window just after we receive big amplitude signals.
I present you the last example for Afyon, Turkey EQ (M=6.5R). Bar graph below shows the mean daily tidal gravity curve for February 2002. From the other hand, in my signals graph (see my previous response) you can see that the signals were raised at the end of January. So, the most dangerous days was the 3rd, 4th an 5th of February (red bars).
This was proved absolutely precise as you can see on the above bar graph.
ATTENTION: This graph does not mean anything without existence of signals.

HOW WE CAN FIND WHERE IS THE EPICENTRE OF THE ONCOMING EQ
We use the signals from the two crossing dipoles as components of the total signal. We can calculate the azimuth direction by applying simple physics. I found the precise direction of the two receiving dipoles by use of GPS instrument. A special computer program can scan big number of data and calculate the azimuth direction very fast. So we know the azimuth direction for the source of the signals by running this program.
I will use the example for the Afyon, Turkey EQ again. On February 2, we found the azimuth direction at 93 degrees, by running the above program. That is to say almost easterly concerning my station. (The precise azimuth direction of the real epicentre was 97 degrees).
You can see on the above map the blue-red arrow that shows the azimuth direction that was calculated on February 2. I notice that the distance of the epicentre was about 722 Km from my station.
Unfortunately, we have only one station and we cannot calculate the precise place of the epicentre on this line and also to approach the precise magnitude of the imminent earthquake. Are required at least two additional stations that we do not have until now.

We use this graph when we have significant signals. The three more dangerous days for an oncoming EQ are these, which are centered the lower or the upper peaks. I will update this graph every month.

Hi all
Impressive graphics John. Is it possible to see a long term pattern to the fluctuations yet. By being able to read long term patterns you can sort of make a rough guess as to what the future holds. Keep up the good work and let us know what happens from here.

I recorded a new strong world signal yesterday. I don�t know much for these signals. I found that during 9 or 10 weeks after the signal will become a big EQ somewhere in the world. I can�t find where. Its magnitude will be greater than 6.7R.
This is my yesterday record. (24 hours)
Since August 1999 I recorded 80 similar signals and they happened 78 EQ's with magnitude greater than 6.7R around the world until this moment.
A good question is "How and why these signals can arrive in Volos?"
I cannot answer by my self. Maybe the explanation is here:
http://serpiente.dgsca.unam.mx/serv_hem/revistas/fisica/1997/01/koshevay.html
The fact that these signals they have about the same amplitude it increases the possibility of an electromagnetic world resonator with constant quality factor. They differ only in the duration, which is not important.

The earth has been describes as ringing like a struck bell when an earthquake hits. Waves travel around the world just as waves do in a pond when a stone is thrown in. In this lake case, the waves do not happen until the event. Might there be some precursor event you are sensing? We are just in our infancy in understanding the dynamics of the earth. I wish you had more monitoring stations. If I knew what to do, I'd do it immediately to assist your research.

We have been informed via our exports in Western Australia that we are due for the big one very soon. Some thousands of small and some larger quakes have been happening in the last few months. Perth has been shaken a few times recently and we have been told to be prepared.

Hi Anne,
I am not expert but I can say something due to my experience. I don't know if these many quakes are the only criterion in order they can say anything for an oncoming strong quake. It secure if we say that their area is seismically active. But this is not meaning that it will become a strong quake there. It is good sign if you have big number of small quakes because they reduce the stored energy. It reduces the possibility for big earthquake.

John

Indeed Anne, I had also heard the same comments. I suggest the media not give these people air time or paper space because it alarms but does not inform. Please keep in touch. I thought about you when I saw it mentioned. John is correct. And, yes he is an expert. His data is far more reliable than others who have lots of letters after their names and who hold high positions.

Yet again our news media are going on about the big one. Its unbelievable that they can continue with these scare tactics. We are in the middle of a dreadful drought and I am beginning to wonder if they are trying to get us away from the truth and scare us into worrying about the earthquakes being imminent. I am finding myself neither trusting politians or the media these days. Do you find yourselves in this position.
~MarciaH
Thu, Apr 4, 2002 (13:12)
#24
Yes, Anne, indeed we do find ourselves searching for information which is not there. The politicians do not want to know what might happen because they will be responsible in the event that they misjudge the danger. Has it really come down to the fact that we are a litigious society so completely that NO one wants to become involved? I fear that is the situation.
If John's worthy research does nothing else, it will at least inform those who will read it to see what is actually happening to the earth at the present moment. Perhaps we need to make a little enclave of watchers and informers of our own space. John's world predictions will be better when he has more stations world-wide. My substrate waits for instrumentation, and my son's does, as well. I think I need to light a fire under my son, since he is making his own.
I thought your drought had eased. Good grief, it has been years in length by now. Do you have wildfires again? Drought is not something I take lightly. I live on a very finite island and if we do not have enough rain, we are affected immediately. I'll send you monsoon thoughts and a bit of our tropical rain soakers to your watershed.

I want help you Anne.
I don't know on what strange or unusual phenomenon they based on and they say something so serious. On what they give reason for their prediction? If you heard something please tell me. But looking at the seismisity map of your area (below) I found only a few small EQ's on the solid earth of Australia. They are not give reason for a big earthquake I think.
We have three to six EQ's in Greece every day with magnitudes 3 to 5R but the big EQ's are infrequent. I noticed a big number of EQ's with magnitude from 3.0R to 4.8R within a few months in a small area many times. But a big one never came.
They have enough small probability of confirmation, if their prediction is based on statistical data alone. I suppose that they have not any additional information or observation.
In any case you can e-mail me any time.

Thank you John for your offer of help I will certainly inform you if any more comes from this area. Marcia I know this isn't about earthquakes but I live in Western Australia which is supposed to be under severe drought yet the strange thing is where I live we have had quite a bit of rain during the past month and the people who run our weather centre says we have had none! I find everything very strange these days. They have now stopped talking about earthquakes and the big one - all the talk is the fact they have run out of money and need more. So I suppose it is leading up to severe charges for water etc.

Anne, as soon as John can get back online, you will discover that your situation is not unique in the world. I thought fear of science was what separated politicians from the facts they need. Now it appears they do not WANT to know what is happening so they will not be held accountable. I'm not all that sure we are any better off with the best equipment on earth staffed by the USGS.
You would think they would use some sort of diversionary tactics to keep your mind off the water problem if they were not preparing you mentally for large increases in rates. I suppose catchment is out of the question. That is what people here do when they tire of being yanked around by the politicians and public utilities. I've never considered that option. Drinking greenish water is not my idea of civilized living. I think Rob, in New Zealand will also tell the same story. How odd, though, that you have had so much rain but not enough, apparently!

Hi all
At 10:51 UTC today it happens a significant earthquake in distance of 360 Km almost north of Volos. It reported by USGS:
Date-Time 2002 04 24 10:51:51 UTC
Location 42.43N 21.51E
Depth 10.0 kilometers
Magnitude 5.5
Region NORTHWESTERN BALKAN REGION
Reference 25 miles (40 km) SE of Pristina, Yugoslavia
Source USGS NEIC
My signals was low but not at the absolutely background level. My original signals are updated daily in Geo portal. After FFT process in 22nd April on them, we have the following particular signals:
And the azimuth direction that was calculated is:
Red circle is the place of the real epicenter of today�s earthquake.

It seems that each time I sleep the rest of the world does amazing things. What we need to do is to get you other stations whose data you can coordinate with those of your own monitoring station. How we can accomplish this is someting I cannot even begin to understand, but I do know two people who have offered you their far-flung substrate for your use.
From the grahpics Dr Thanassoulas worked up from your data, this earthquake does not surprise me in the least!

Hi all,
Unfortunately I recorded a new strong pre-earthquake signal yesterday. This type of signals comes before Big Earthquakes anywhere on the Earth. The eventuality is near 100% in order to be realized. This is my signal from the recorded file:
This is meaning a Big Earthquake (greater than 6.7R) within next 2-3 months. For more information about this type of pre-earthquake signals you can see in Geo Portal:

If I could make one by myself, John would already be getting data from my substrate. I think I must urge David to get his station built and installed. This is very important basic research John is doing. We must help in any way we can.
Speaking of advance warning, I audited a course of college geophysices this morning and was appalled to know that all the USGS said they could hope for was a few minutes warning so people could get their water bottles and food and turn off the untilities before the earthquake happened. That is not going to save lives. Can they be so blind to research that they cannot do any better than that? Our tax dollars are not being well-spent if this is the case.

Wolfie, John will tell you and I will agree that politics and ego problems preclude co�peration. Even when the public good is at stake, no one seems to want to know about this danger because if they know, then they will be responsible for protecting and taking care of us. If they don't - think of the legal implications.
Also, John is not part of the establishment academics with geology or geophysics degrees. It seems, when some scientists have their degrees they feel they can stop learning and researching. They do not appreciate "outside intelligence" making them look foolish. They think with their egos and not with their itellects. But, in this case, that is exactly what is happening.

I am expecting a world quake - or several, but it is the imminent local quakes that concern me. I can predict it happening soon if not immediately! Look at John's signals for Greece. We are also in the dnager window. Then next one is around my birthday. I hope Gaia does not celebrate with earthquakes!
No, I would not wish Einstein's brain on you. He had a difficult life and was forced to live in a world that he really did not fit in. An agile and inquisitive mind is the best. You can think and inquire in many directions, John. That is really the best of all possible worlds. (I also think your classmates were a little envious of you - you looked younger than any of them!

Welcome to GEO George.
I think that you are Greek. It is wonderful! Where you live in Greece?
It is a form of signals that appeared also before strong EQ�s like the big one in Ismit (Turkey, in the August of 1999 7.5R) and the Athens EQ on September 1999. But how do you know that peaks? They are not readable in my graphs.

Marcia and John, thank you for your warm welcome messages! May I take the opportunity to extend my greetings (from John's part of the world) to all participants of GEO.
Yes John, you are right; I live in Athens.
In response 40 you present a graph of your record of May 12, 2002. There are 3 large peaks in the record (one of which you interpreted as a World Signal) and 89 small peaks, so there is one small peak every 16.2 minutes. The small peaks seem to be superimposed on your signal (the apex of the world signal peak looks identical to the small peaks). All small peaks have the same amplitude, their spacing (period of the oscillation) is constant and their shape looks identical, although (as you pointed out correctly) I cannot see their exact shape at the scale of your graph. This oscillation lasted from May 7 to May 19 with a small break in the early hours of May 19. I think this oscillation is too regular and too persistent to be the result of a physical (natural) process, but on the other hand I am not a specialist in the analysis of geophysical records.
The questions are: 1) Is this oscillation really as regular as it looks at the scale of your graph? , 2) Is there a physical process that could generate such an oscillation? and 3) Have you tried to isolate and analyze this (strange, as you call it) oscillation?
I just noticed that Dr. Thanassoulas has added a new page ("Last Large Seismic Event in Greece") in his site. In it, he describes the above oscillation as "high frequency (SES) signal". I guess, that answers part of my questions, however I would like to have your opinion on the rest.

Hi George,
I am glad that I find you here. I am happy also for your good and realistic questions.
Yes George, you are right; I was forgotten that I posted that graph. Indeed they are pulses with almost constant period, constant width and constant amplitude. I made all possible checks during the presence of these signals because I had the same questions with you. I found that it was real signal in the nature finally. The signals disappeared so suddenly as so suddenly appeared. Now I can say that these signals were not man-made. I am absolutely sure.
I know electronics very well but not so well geology. Dr Thanassoulas has enough experience from the signals of VAN group. They are SES signals with the same shape as he says and as he has showed me. I remind you that the SES signals are those who examine Dr. Varotsos and VAN group.
From the other had the 24-hour period oscillation was significant and about constant. The azimuth direction was also about constant to the south-south east direction in a wide area of the electromagnetic spectrum (see Dr. Thanassoulas analysis).
From my side I notice the red line in my graph of the recent signals. It is in middle position of the oscillation and it gives the sensation that represents the increasing of the pressure at faults rims. (It is my opinion but also Dr Thanassoulas agree).
You ask me if it is there a physical process that could generate such an oscillation. I can't answer. But it is a real fact that needs an answer. Perhaps we need some help from other sciences.
In any case we make a research. That means that we have always-new questions and we try to answer. We are learning nature with this new eye finally. Our results on the earthquake prediction are absolutely positive independently of what theory can explain it.
A new article was published today in Greece about our work. It is in the newspaper Thessalia of Volos. You can read it in this address:
http://www.e-thessalia.gr/newsfeed.asp?Fv1=1&Fv2=27/5/2002&Fv3=&Fv4=6572
Unfortunately for our friends here it is only in Greek language.
I don't know about your studies George. If you have any new idea, it is welcome.
Warm wishes from Volos

Thank you for your prompt and honest answers to my questions, John. I apologize for my short disappearance, but I was out of town for fieldwork.
I am a marine geologist specializing in coastal processes, nearshore hydrodynamics and remote sensing. For more than sixteen years I have been using a digital data acquisition system, that I have developed, to record and analyze sea waves and currents, wind speed and direction, air and sea temperature and other environmental parameters. All records have been analyzed in both time and frequency domains using time-series analysis techniques. You would be amazed to see how similar some of our records look!
For several months I have been studying the records and the analyses that you and Dr. Thanassoulas have been posting in your sites. I am convinced that most of your records represent a real signal and not any type of noise. I do not know what kind of signal they are, or how they are produced, but their correlation with earthquakes is impressive!
The piezoelectric mechanism, described by Dr. Thanassoulas and others, seems plausible but (in my opinion) cannot explain signals like the one you posted here in responce 40. Your records of May 12, 2002 and some days before an after that, are completely different from anything that I have seen in your sites during the last six months. They are also different from all examples of SES signals that I have seen in Dr. Thanassoulas' pages and in published works of the VAN group. In fact they are so different that you described them (correctly) as "strange periodical oscillation" and "pulses with almost constant period, constant width and constant amplitude". I find it extremely hard to accept that any physical process (piezoelectric or other) could produce such constant electric pulses in a switch-like manner for so long. That's why I got curious and I asked your opinion about it.
I have to stress that the above comments are not an attempt to diminish the achievements of your research efforts. Unexpected, strange and unexplained results tend to pop up regularly in earth science experiments. They help us draw the line between things we do and things we don't understand and often they become the necessary stimulus for us to re-evaluate and improve our experimental designs.
Thank you, once more, John, for taking the time to answer my questions. If I could help you in any way, I'd be glad to! Best wishes from Athens!

Thank you George for your frank reply.
Furthermore, I am sure that your own perennial research, even if in neighbouring sector, it contains enough strange and unexpected discoveries that ask answers.
I must say to you that it is not the first time where I recorded similar signals. I am sure that these signals are REAL without question. The station of reception functions in the house where I live and I watch what it is recorded in real time. Thus I can make the required tests each time when I have doubts.
Your object is exceptionally interesting. Perhaps you could say to us more about your work here. Also, I think that it must be very interesting and useful for both of us a real discussion for our experiences. I like this idea.
You live in Athens. Would be interesting to me a meeting with you. My children live in Athens too. I visit them some times. Also, you can visit my station if you come some day in Volos. We can communicate directly by e-mail.
Thank you again George.
My best wishes

Hi John.
I am sure that you double- (and tripple-) check everything before you post a graph that contains a world signal and a SES signal! If you and Dr. Thanassoulas are convinced that the strange oscillation we talked about is a SES signal, then I am convinced too. It seems that this signal was the last warning before the Milos earthquake. I am sure that you have been investigating the nature of this oscillation (especially since you have recorded similar signals before) and I hope that you will discover the process that is responsible for its peculiar characteristics.
When I talked about unexpected, strange and unexplained results I did have in mind some examples from my own research. A couple of them have to do with bizzare instument behaviour that could be published in the Journal of Irreproducible Results, but the rest were really intriguing and provided the most interresting scientific results. One or two still remain unexplained...
Maybe you could give me a hand with those!
I look forward to meeting you either in Athens or in Volos and I certainly would like to learn more about your research, your experimental design and your experiences!

Hi George,
Thank you for your scientific position. I must inform you that in my site are presented the signals as they are recorded without any processing. I find it useful in order to be clear what is recorded in the original form.
The signals are processed and analysed by a special program that we have constructed. Dr Thanassoulas makes this work also everyday and publishes the results CAREFULLY in his site. We do not analyse SES signals but we are seeing them. We examine mainly the 24h period signals and the entire electromagnetic spectrum with periods greater than one hour.
The term World Signals is mine. They are very big reductions of the recorded level. Its amplitude is about constant but not the duration. Correlation factor of these signals with big EQ�s (M greater than 6.7R) everywhere on Earth is very close to 100%. Dr Thanassoulas has no time to spend with them. But they are very interesting as well. They remind me the response of a resonator with constant quality factor and appeared only in the North-South dipole. Personally I can�t find a way to examine them longer. Perhaps you have an idea. It seems that Schuman Resonator theory can explain them but I can�t proceed with my means.
I hope that I will have a chance to see you the next weekend. Perhaps we can discuss also with Dr Thanassoulas directly. I think that we have to learn from each other knowledge and experience. I hope you will find some time for it.
Regards
John

Hi all
Picture this if you can - an apocalypse in the world biggest
metropolis, powerhouse of the Japanese economy, national capital, and
home to 34 MILLION people. No, this is not the aftermath of the yen
caving in, but a scenario of what will happen in Tokyo when the
expected major earthquake hits. Despite Japan being a world leader in
earthquake preparedness and having a record a mile long of
destructive events, the reality is not entirely what one might
imagine of Japans economic power. This essay examines what may happen
in the Tokyo metropolis in the event of a bad earthquake. It answers
three questions:
1)Why is Tokyo at risk from bad earthquakes? A geological and
engineering perspective.
2)What is likely to happen in an earthquake?
3)What has been done to protect the city?
For the purpose of this particular essay, a magnitude 8.2 earthquake
centred 15 kilometres from Tokyo at a depth of 20km has hit the city.
The death toll reaches 300,000. Aftershocks have magnitudes of up to
7.3 on the Richter scale, but there is no tsunami.
Why is Tokyo at risk from bad earthquakes?
The Tokyo metropolitan area sits near the junction of three tectonic
plates. Along the boundaries of these plates a colossal amount of
stress is building up in the crust which is deforming the land. But
like a rubber band you can stretch the rocks only so far before they
snap. Well along the plate boundary there is numerous ways an
earthquake can be generated. One is that the plates are sliding past
each other like in the case of New Zealand and the United States.
This means the rocks might be locked in place by their physical
location and properties and so a large earthquake is required to move
the rocks. Another is subduction. The diving plate is generating a
lot of heat (melting rock creating magma)and friction which causes
earthquakes along the subduction zone (Hikurangi Trench - NZ, and off
the Alaskan coast, and of the South American coast).
Tokyo also sits on alluvial plains which might be vulnerable to
liquefaction in an earthquake (liquefaction is when the groundwater
comes to the surface bringing sediment with it. Buildings might sink
into the saturated sediments to a depth of a few metres or more
(Niigata, 1964 is a prime example). So infrastructure and buildings
are at risk from sinking into liquified sediments and the costs of
building deep foundations is quite high so construction companies
generally try to avoid it.
History tells us a lengthy tale of some catastrophic events for the
worst would have to be the great Kanto earthquake of 1923. It
measured 7.9 on the Richter Scale, and destroyed Tokyo and Yokohama.
140000 people were killed in the earthquake and the firestorm that
followed because of the busted gas mains. And it was worsened when a
localised tsunami came ashore.
When all hell breaks lose - the likely problems.
You get to your feet, and your head is swimming. You cannot think
rationally and are incoherent. Your house is a wreck - broken
windows, masonry, walls, an amazing mess on the floor from your
cupboards, pantry and shelves. You go outside and it looks like a
nuclear bomb went off minus the radiation. Powerlines and power poles
are down in a chaotic tangle sparking and cackling. Broken water
pipes send floods of much needed water pouring down the roads, and
with no water pressure for that reason, the fires spread. Ruptured
gas mains fuel the fires and start even more. Collapsed buildings
block roads and hamper emergency services trying to reach the
wounded, the fires and few places where water is freely available.
Add to all this, after an earthquake the size of the one that is
likely to hit, one could reasonably expect a tsunami to add to the
misery since any offshore event would have displaed a vast segment of
the sea floor. Not to mention the aftershocks that will go on for
weeks and maybe almost as strong as the initial event. Finally,
though maybe this would not occur in Japan, to top of a truly
horrible situation, there is the risk of disease from the dead and
the dying plus the shattered sewage mains.
With the onset of the earthquake, the Yen loses 15% of its value in a
hit and 25% in three days, wiping billions from the Japanese economy
and causing an exodus of sorts of investors in Japan. The economic
shockwaves are felt around the world and the exports from Japan take
a dive.
What has been done to protect the city?
To be fair because of the severity of such an event, Tokyo has
stringent plans in place to deal with something that everyone not
only knows is coming, but get reminded by nature every few weeks.
Tokyo has a network of radial and ring roads/railways that emergency
services will have priority access to after an earthquake to speed up
the relief operation. These are backed up annually by a massive Civil
Defence exercise, involving the armed forces, and the emergency
services on every September 1 (the day of the Great Kanto earthquake)
to test the readiness and efficiency of the emergency services in
dealing with a variety of tasks. Tokyo has also built several large
shelters with water systems installed so that people may take shelter
from a large firestorm in the event of an earthquake. This would
avoid in theory the horrendous loss of life in 1923.
However there is also a shady side to it all, most notably in the
construction sector where sometimes money speaks louder than human
lives. So one is rightfully disappointed when it is said that bribes
are offered and sometimes accepted to cut corners in the earthquake
building code to save costs by not properly reinforcing buildings,
using second grade steel and possibly not using the correct
techniques (like inserting steel rings in concrete piles supporting
raised motorways and so on). Because this represents the most
shocking loss of face to the people involved, you will almost never
hear about this in the press.
Conclusions
After reading this one can certainly say that Tokyo and the
metropolitan area surrounding it is in for a rough time after a large
earthquake. However one hopes the civil preparations will ease the
situation and prevent a catastrope. So maybe the people of Tokyo will
be spared the shocking events of 1923 where a large earthquake
spawned not only a firestorm but was followed by a tsunami and this
combination led to a horrendous loss of life. At the end of the day,
the question is not IF an earthquake is coming but WHEN, and how BIG
it will be on seismic scales.
But if it lives up to the reputation of the infamous 1923 disaster
which killed 140,000 people, it really will be the 60 seconds that
shook the world.

Excellent example Rob.
Unfortunately big cities around the world are very defenceless to a catastrophic event like the EQ.
The reason is only one. They are builds based only on economic standards. This is also the main reason that makes difficult any effectual emergency plan. We will wail for thousands lives until the day when each one of us will have as first priority the safe life against the economic parameters.
We place much more reliance in our technology than its limits. From the other hand the political cost is high if they know for an oncoming EQ and it will cause victims. So, they prefer to say that EQ prediction is impossible until today! It appears impossible but is real.

Early Warning for Earthquakes
Izu Islands, Japan
Tuesday 9th July 2002
Earthquakes may signal their impending arrival by radio, according to scientists in Japan. Seiya Uyeda and his colleagues have reported measuring anomalous variations in the electrical and magnetic fields at Japan's Izu islands since the end of March 2000, and within about three months of a series of earthquakes. Using telephone wires as antennas for very low-frequency radio signals, they identified changes in them over the three-month period preceding the quakes - and a peak in their amplitude just before the first large earthquake on July 1. With very little chance that the signals are man-made, the work lends strong support to the idea that earthquakes may be predictable by careful observation of very low-frequency electromagnetic disturbances.

PROFESSOR OF GEOPHYSICS CLAIMS TO HAVE PREDICTED THE EARTHQUAKE
Athens, 29 July 2001 (21:05 UTC+2)
Research according to which he expected an earthquake of 5,7 R to occur in
Greece two days later, when it actually did, was submitted on the 23rd of July
in a seminar in Bulgaria by Geophysics Professor Konstantinos Thanasoulas.
Mr. Thanasoulas has been researching the prediction of earthquakes since
1982, but only just last year did he manage to get any results, after his
cooperation with Giannis Tsaragos, electronic engineer.
As he stated to a local television channel, STAR , before the earthquake there is
a deformation in certain rock formations, which creates an electrical field and by
applying simple mathematics one can find the source of this electrical field.
Mr. Tsatsaragos pointed out in statements to the same channel, that in a length
of time under 15 days from when the widening of the electrical field begins an
earthquake is expected.
The two scientists' station showed indications of an upcoming earthquake from
July 20th up until 20 minutes before the earthquake took place in Skyros.
The scientists point out that they can predict the intensity and time of the
earthquake, but not the exact epicenter because they only have one station at
their disposal.
After the verification of their prediction the Bulgarians showed interest in Mr.
Athanasoula's method. The interest was not shared by the Ministry of the
Environment Physical Planning and Public Works or by the Organization
Antiseismic Protection, who were informed about the research and its results.
In any case, in scientific research that took place in 1993 in the seismological
lab of the University of Athens, the epicenter and the intensity of the earthquake
in Skyros had been predicted, but the exact date had not.

�SECRET BREACHES� WORRY SCIENTISTS
Athens, 29 July 2001 (20:25 UTC+2)
Great unrest has been caused among seismologists, by the dozens of "secret
breaches" existing in the Aegean, and that seem to present "secret threats".
Many Greek and foreign specialists seem to be troubled, since after the great
earthquakes of Turkey and Parnitha they have expeditiously arrived to chart the
until recently unknown breaches.
History has shown that most of the catastrophic earthquakes have been caused
by these "secret breaches", and in fact in areas that are considered non
seismogenous, just as it occurred with the Fyli breach that caused the 5,9 R
earthquake in 1999.
"The study and charting of the specific breach is almost near completion. Thus,
for the first time we know all of its characteristics", stated the
seismologist-researcher of the Athens Observatory's Geodynamic Institute,
Gerasimos Papadopoulos.

I am very confused with these big signals. I have one per day during the last days! I recorded also one new signal yesterday. Here is:
I am searching also other possible explanations. Have you any idea for a possible physical phenomenon that is quantic and it can absorb part to whole of the existing electric field between the N-S electrodes? I think that the NMR phenomenon not match because the Earth�s magnetic field is not enough strong.
You are right. SES signals also appeared. From the other hand the 24-hour period signals are enough higher from the background level. We will see the continuance. It is very interesting.

Hi Marcia, George and all.
Thank you George. Meanwhile, I had a new big and unusual signal yesterday (because it has positive polarity). This signal is the third during the last 4 years that is so big with positive polarity. I can�t say anything for it. This is what I recorded during the past 24 hours:
It is also welcome any possible idea that possibly helps to explain this phenomenon. I am sure that all of my big signals are not depending on ionosphere variations, human activities and weather interactions. In contrary, it appears that the levels of the variations of these signals are following steps just like as the energy levels in a quantic phenomenon.
I underline also the two big EQ�s today (7.7R and 7.5R) in the region of Fiji Islands:
2002/08/19 11:08:25 23.81S 178.36E 693.7 7.7 A SOUTH OF FIJI ISLANDS

Marcia, if you succeed with the weather, I am sure that John and I will be able to think of a couple more requests...
To thank you for your efforts, I will send you some really nice photographs from Santorini as soon as I get back to Athens.
Your question about the laptop is easy to answer:
First, I have bought my children a computer of their own, so that they will let me work on mine. But, as they both "need" the computer at the same time, they take over my laptop. However, they are really good kids and let me "play" with my laptop when they don't "need" it!*smile*
Just in case we all need the laptop at the same time, I have a faster procedure to regain control of it. I offer to compile a list of observation times of satellites for the evening! I get my laptop back in no time, and we all enjoy a couple of hours in the evening spotting satellites and meteors and talking about anything you can think of...

Spotting satellites!!! I am looking forward to doing that with MY son and his wife when I return to California next week. I miss having a clear sky. It is clear here, but the air has so much *stuff* in it that it eclipses just about anything less bright than the moon and Venus. It is very disappointing, though I suspect the entire eastern part of the US is just like this.
Good father, you seem to be. Your children will honor you if you can hang in there long enough, George! I know about *needing* things. I guess it was ever thus with parents and children.
I'm working on the weather. Actually, the eastern US is requesting all of the snow this year. I think one should be careful for what one wishes. You just might get it! They may live to regret the abundance of snow, yet!
Santorini??!! Oooh. You said the magic words. A volcanology/geology professor is doing Ground Penetrating Radar images of the Thera tuff so archaeologists are not wasting time digging holes in vacant spaces. I was so envious when I watched his slides. He was most complimentary about the people and the country of Greece in general. I agree.

Excellent news about the laptop. No one should be without one. I am even coming to like the little keyboard (I have small hands) and do not make as many errors as I previously did with it. Actually, I am quite happy with how compact and ready for field work it truly is. At home, I have it sitting on a little swiveling circular platform ("Lazy Susan") so I can download photos taken on archaeological trips and show them to Don. It works very well considering he is across the table from me. I also have it raised upon a heavy metal perforated disk to keep it cooler. Actually, what it was is the metal cover from this old home's basement drain. It is about 12 inches in diameter and is quite heavy.
Laptops can be upgraded as I found out. Get what you need and work from there if necessary. Of course, we all like it with the maximum capacity and speed straigh away.
You are correct, John. You know me too well! I am not the mouse in a corner type, but I do try to listen carefully and ask good questions. I truly enjoy sharing discoveries. But, you know that!

(I am not always correct. Horrors! But how kind of you to think I am. This lofty throne has room for two of us. Your name also graces the cover page for this conference!)

Satellites give new view of quakes
By Dr David Whitehouse
BBC News Online science editor
Radar detects how faults slip
Data obtained from satellites is providing scientists with a new way to analyse the movements in the Earth's crust that cause earthquakes.
Previously they had to rely on a series of spot measurements across an earthquake zone.
The new data on rock movements comes from satellites that bounce radar signals across a wide swathe of the Earth's surface.
The new insight may provide a way to study earthquake zones and predict when and where quakes may strike.
Conventional wisdom overturned
The earthquake that provided the new information took place on 16 October 1999 in California.
The quake, of magnitude 7.1, caused only a little destruction and no injuries because it occurred in an area with a sparse population and development.
Strain builds up before a quake
Satellite observations of it produced information about never-before documented features of faults. These include the first evidence that faults move backwards, contrary to conventional wisdom.
Yuri Fialko of the Scripps Institution of Oceanography, US, says the research provides a new way to identify potentially active faults, and perhaps a better understanding of the earthquake process.
Dr Fialko says the earthquake was the first one to be comprehensively imaged using so-called synthetic aperture radar that reveals minute details of the fault's movements.
According to a paper in the journal Science the fresh data has given researchers a new window into earthquake processes.
The most surprising finding was the first evidence that faults can move backwards. Prior to an earthquake, faults are locked in position by friction.
"Even small stress perturbations from distant earthquakes can cause faults to move a little bit, but it's only been known to cause this motion in a forward sense," says Dr Fialko.
"Here we observed the faults slipping backwards due to relatively small stress changes, which is really quite unusual."
Soft rock
The data also suggests that rocks in fault zones are more pliable that the rocks that surround them.
"The material within the faults is mechanically distinct from the material surrounding the faults," says Dr Fialko. "The rocks within the faults appear to be softer."
He believes that fault zones become strained during periods of stress and begin to act like a soft, sponge-like material.
According to Dr Fialko, the results will guide new seismic studies to areas with contrasting fault material, such as that seen in the Eastern California Shear Zone. They can then be used as a way of identifying potentially active faults.
"Measurements of changes in the mechanical properties of faults may yield valuable information about the earthquake cycle.
For example, we might be able to say how long it was before the fault experienced an earthquake and how long it takes to heal," he says.

***********************
I could say that I had observed a decreasing of the pressure at the fault rims a few days before the main earthquake. Excellent example appears in my recordings before Skyros EQ (M=6.3R) on 26th July 2001. You can see clearly the decreasing of the amplitude between 19 and 20 of July:
The above article from BBC becomes now very interesting.
