Hi all Well I remembered Karen has the Drool Conference where there are many Colin Firth subjects with 2000 messages, which points to one of (or both)two things: Colin Firth is a god to Drooleurs, or Colin Firth gossip is the only thing worthy of talking about. But Marcia, please leave it up there unless you are having problems managing Geo because it is a tribute to it's popularity as a subject here. It must be (in my humble opinion)the former, because the second possibility is impossible. Although it is many thousands of messages behind Colin Firth in popularity, I think seismicity has done much to contribute to our life and not necessarily in negative ways. Seismicity many people understandably loath because it usually brings destruction, injuries and scares the hell out of people but our understanding of the Earth would be in the Stone Age if it were not for earthquakes. We would still be having Tangshan size disasters because no one lived in buildings that adhered to a modern building code, building on faultlines would still be okay. There is much to be learned and shared about the future of seismicity in human life, so this is a welcome forum for it. Rob

Rob,this is how I get to all Geo topics. If I loaded them all from post 1, I would never get anything done! http://www.spring.net/yapp-bin/restricted/read/Geo/88/new

If I feel another earthquake after August 1st, I am on the New Madrid fault system. Tomorrow I will be on various faults connected to the San Andreas Fault. I think I might be safer in Hawaii, albeit miserable!

Hi all When you say you are leaving Hilo, is this saying "Haere ra, Hilo", as in "Goodbye Hilo"? I think you just moved yourself to a lower risk, but higher consequence area in moving to Kentucky. I am not aware of fault systems in Hawaii where a magnitude 8.0 earthquake is possible, but the NM fault system HAS generated earthquakes of this size, and would appear capable of doing it again. The New Madrid Fault is not well known and not visible from space (not like the Alpine Fault in NZ where the abrupt edge of the Southern Alps as seen from space marks the fault), so it might be difficult to convince the Midwest of the danger. New Zealand is lucky when it comes to spotting faults from imagery shot in space, because there are several geographical features clearly marked, which on closer inspection could be influenced by faults. The Wairau River in the northern South Island runs due NE from Lake Rotoiti in the Nelson Lakes National Park, and is almost completely straight when you look at it on the map. That is because a large fault runs parallel to the river and dominates the geological structure of the valley. This is actually the northern section of the Alpine Fault, and it passes within 7km of Blenheim (population 25,000). The fault disappears out to sea where it terminates. Rob

I left Friday and am on the San ANDREAS fault system now. I will not miss my little part of purgatory. It is lovely to visit Paradies. It is wretched to try to live there like it was part of the rest of the world! If Kiluea is going to crack in half (the crack grows daily) and fall into th sea, I'd rather not be there. The Big Island of Hawaii is long past overdue for another damaging eqrthquake. I am happy to be gone, but I do wish the EQ would hold off until I have sold the house. The good news is that my eventual home in Tennessee (in two years or so) is almost seismically inert.

Kia Ora No NZ is not an island arc. The country consists of two large islands and a host of smaller ones either scattered far and wide like the Chathams, and Auckland Islands or coastal like White Island. An island arc as nearly as I know is a chain like the Marianas where you have a string of islands sitting opposite to a plate boundary (marked by a trench - the plate boundary is on land in New Zealand, running down the West Coast of the South Island). New Zealand is a submerged continent of which the islands are the 10% that we can actually see above sea level. If you lowered the sea level to the continental margin, the Waimakariri would actually end up taking the combined flows of itself, the Ashley, and several other rivers north of Christchurch. Cook Strait would be considerably narrower or might even completely disappear and Christchurch would be high and dry with the coast several hundred kilometres to the east. Rob

You are right about what creates an island arc. I had no idea a submerged continent was your bedrock in New Zealand. That should make the possibility of earthquakes much less for you, but that is not the case. You lie on the subduction zone of the Pacific ring of fire?

Hi all Yes. We are just like the US in many ways. Both countries have a segment of plate boundary that is offshore (US Gulf of California and off the West Coast; NZ along the Hikurangi trench off the east coast of the North Island). Both countries have onshore segments of plate boundary (US San Andreas Fault; NZ Alpine Fault). New Zealand has an active volcanic chain through the central North Island and out into the Bay of Plenty, where over 50 more volcanoes are to be found on the sea floor. They are all subduction volcanoes caused by the collision of the Pacific plate which has oceanic crust, and the oceanic crust of the Indian plate. Where it reaches the Bay of Plenty the angle of collision starts becoming increasingly oblique moving WSW as it collides with the overriding Indian plate. A well established Benioff Zone is found there and right along the Hikurangi Trench section of the offshore boundary. Further along still, there is a collision between oceanic and continental crust. It is this collision and chemical change that creates the magmas that fuel the "Dirty Dozen" onshore New Zealand volcanoes. Questions? Rob

Hi all Continuing where I left off. Under the South Island continental crust collides with continental crust at an oblique angle, with the eastern SI slipping SW, and the western part slipping NE. This is pushing up mountain ranges in the northeastern South Island by creating strike slip faults with some dip slip, as expressed in the Seaward and Inland Kaikoura's where altitudes reach 9,000ft. Three large faultlines run SW-NE across the northeastern South Island, and are the Clarence, Awatere and Hope Faults. All three have built significant mountain ranges which have short steeply graded rivers running off them, where flood times can be as short as a couple hours. Rob

Hi all Had a magnitude 5.4 earthquake on land in the lower North Island overnight. The earthquake was felt strongly throughout the lower North Island, and was centred 20km E of Pahiatua at a depth of 50km. In January, a magnitude 5.6 earthquake not far away cleared shelves in two supermarkets. The Wairarapa is the most seismically active part of New Zealand because of it's proximity to the plate boundary offshore. Earthquakes tend to be bigger in Wairarapa because the crust is stronger, and more stess has to build up before things break. Further north it is more elastic and stretches. Rob

This is great stuff, Rob!!! A light earthquake occurred at 12:00:53 (UTC) - Coordinated Universal Time on Sunday, August 3, 2003. The magnitude 4.2 event occurred 6 km (4 miles) SW of Cobb, CA. The hypocentral depth was 2 km ( 1 mile).

Kia Ora It is. The earthquake has caused about 250 claims for damage from the coastal Wairarapa and inland parts of the lower NI. A magnitude 4.6 earthquake rocked the lower NI later that night and is assumed to be an aftershock, because it was in the same location, but a few kilometres deeper. On average each year, we get about one M 6.0 earthquake on land in NZ. The last earthquake to exceed M 6.0 on land was at Cass in 1995, and was M 6.2 Rob

Kia Ora New Zealand is in a bit of a drought as far as earthquakes on land go that cause damage. There has not been a magnitude 7.0+ earthquake ANYWHERE on land in NZ since 1968, when Inangahua was rocked in June of that year. It measured 7.1 and was strong enough to wake Dad and get him to get under the doorway of the sleepout he was living in at the time. The last earthquake to cause problems was on Saturday June 18, 1994 on a fault near Arthurs Pass in the Southern Alps, when a magnitude 6.7 earthquake (size of Northridge, January 17 of the same year) occurred. Damage totalled about NZ$5 million and caused slips and cracking of road surfaces. An aftershock followed on Tuesday 21 which was almost strong enough to make my school stop work. The day before an independent earthquake with no relation to the AP earthquake measuring 5.8 had occurred. I think most people were a bit rattled. Rob

Hi all This conference by the way, was set up to pick where Earthquake - the Sequel left off. That particular conference is now 1900 messages long and takes forever to open it. This conference is supposed to be part two (I noticed Colin Firth on Drool has 16 parts!). The earthquake topics here have a combined sum of nearly 3000 messages, which is a testament to their popularity. Anyway... The following earthquake has been recorded by GeoNet: Reference Number: 2097975/G Universal Time: 2003 Aug 07 18:17 NZ Standard Time: 2003 Aug 08 06:17 Latitude, Longitude: 38.32�S, 176.35�E Focal Depth: 110 km Richter Magnitude: 5.4 20 km south-east of Rotorua Possibly felt in the region. Rob

oh Rob! Just use the /new link and you only download the stuff you have not read yet !!! http://www.spring.net/yapp-bin/restricted/read/Geo/26/new

ahhhh have new info on White Island. Where would you like it?

Kia Ora In Robs Geo World, would be good thanks. Where is John Tsatsaragos these days, and how come we never hear of his wisdom anymore? Pity that because John has a lot to offer seismology and it was something of a coup to get him posting in here. John, if you see this you are MORE than welcome to contribute. Your knowledge of things geophysical and seismic is a godsend. Rob

I really miss John, too.

Hi all. I am very sorry for my long absence. It is due to strong significant changes (good and bad) of my life afterwards my retirement. I am continuing my research even if with big difficulties and a lot of effort. But the new findings and the new scientific questions are so interesting! Thank you for your good words. I am sure for your feelings about me. I will return soon as possible. My kindest regards John P.S. Happily, the yesterday�s (2003Aug.14) big earthquake in Lefkada Island in western Greece (M=6.3) had not dead people. (I had clear pre-earthquake signals on 9th of August.)

Hi again. Here are my pre-earthquake signals on 9th of August (red flashing lobes) and the two epicenters (dark blue spheres) of the significant EQ�s on 14th of August. Regards John

Kia Ora Welcome and good to hear from you. I found this on Yahoo!. http://story.news.yahoo.com/news?tmpl=story&cid=518&ncid=732&e=10&u=/ap/20030814/ap_on_re_eu/greece_earthquake In February and March we had a lecturer at Uni talking about earthquakes and he mentioned the North Anatolian Fault, which passes the mouth of the Bosporus near Istanbul. The North Anatolian Fault I know to be particularly dangerous, because it ruptures like a domino set falling over. In the current cycle of activity the NA Fault has ruptured on all segments bar the one that passes under the Bosporus near Istanbul. The 1999 earthquake in Turkey was a segment of the North Anatolian Fault rupturing at Izmit, which was closest to the epicentre. Istanbul has 9 million people in it. The next earthquake on the NA Fault is going to be ugly. Rob

Hi all I am okay. The earthquake was at least 300km from my place, but there were small towns in isolated places much closer to the epicentre, out of which it may be proving difficult to get information, because the news has not reported this earthquake yet. The earthquake is dangerous because it was only 12km below the surface, and offshore, so I have not discounted the possibility of a small tsunami occurring. It would have caused slips on the Milford Sound road, and cracked the tarseal I would imagine. Damage is likely to have occurred in Milford which was probably about 35km from the epicentre, and may hamper tourism. The following earthquake has been recorded by GeoNet: Reference Number: 329009/W Universal Time: 2003 Aug 21 12:12 NZ Standard Time: 2003 Aug 22 00:12 Latitude, Longitude: 45.14�S, 166.90�E Focal Depth: 12 km Richter Magnitude: 7.1 70 km north-west of Te Anau Will have been felt strongly in the south of the South Island. Rob

Kia Ora Here is a full account of the earthquake that hit Fiordland a week ago. Rob ---- On Friday August 22, at 0012 hours New Zealand Standard Time, the lower South Island was rocked by a magnitude 7.1 earthquake just of Secretary Island. The earthquake occurred on a subducting slab of the Australian Plate of the Fiordland coast at a depth of 12km, over which a strand of the Alpine Fault offshore lies. This area has a high level of earthquake activity because of the subduction zone, which releases considerably more seismic energy than the onshore boundary does. Near the epicentre it caused over 200 slips in rugged forested terrain all the way down to sea-level. A near-field tsunami with a maximum height of 0.6 metres formed within minutes of the earthquake occurring, which did no damage. Cracks appeared in roads and buildings to the east and around Te Anau, 70km SE of the epicentre where goods were shaken of supermarket shelves, and temporary power outages occurred. With a damage bill of $2 million appearing to be the most likely figure for the earthquake, New Zealanders are generally heaving a sigh of relief that we got let off so lightly. It was felt very strongly in Te Anau and was described as being accompanied by a huge roar like a freight train going past. People in Doubtful Sound dived for cover as they were only 10-20km from the epicentre and a primary school group was trapped by a slip blocking the access road to the sound, from Manapouri power station. In Dunedin furniture shook, loose things fell of the shelves and buildings shook noticeably. It was felt as far north as Christchurch (I noticed the computer table starting to rock, and a diet coke I was drinking starting to slide around). Aftershocks have been frequent and in their own right quite impressive - a magnitude 6.2 earthquake rocked the Fiordland area 2 hours after the first event, and there have been about 25 events in excess of magnitude 5.0. Two days ago there were 3 magnitude 5 events in the space of a few hours, and Te Anau residents are on edge - they just want the Earth to knock it off and let them get on with their lives. Regional Councils across the South Island have leapt at the chance to press home the message that "the Big One" - the now overdue magnitude 8.0+ earthquake on the Alpine Fault is still to come. Considering that a same sized event in 1989 near San Francisco killed 61 people, and did about US$4 billion in damages New Zealand was very lucky to let of with only minor damage. Perhaps it was my comment that summed it best: "New Zealand was very lucky to get off the hook so lightly. This was the seismic variant of the 'Great Escape'". Rob

John! Welcome Home! I did notice the earthquake and wondered about damage. I relied on your assurance of the safety of your house to assure me that you were also safe. And, I did look at your website. This one happened after I left. A magnitude 5.0 earthquake IN HAWAII has occurred at: 19.33N 155.21W Depth 10km Wed Aug 27 06:24:22 2003 UTC Time: Universal Time (UTC) Wed Aug 27 06:24:22 2003 Time Near Epicenter Tue Aug 26 20:24:22 2003 Eastern Daylight Time (EDT) Wed Aug 27 02:24:22 2003 Central Daylight Time (CDT) Wed Aug 27 01:24:22 2003 Mountain Daylight Time (MDT) Wed Aug 27 00:24:22 2003 Pacific Daylight Time (PDT) Tue Aug 26 23:24:22 2003 Alaska Daylight Time (ADT) Tue Aug 26 22:24:22 2003 Hawaii Standard Time (HST) Tue Aug 26 20:24:22 2003 Location with respect to nearby cities: 45 km (30 miles) SSW of Hilo, Hawai`i, Hawaii (pop 40,000) 90 km (55 miles) ESE of Kailua Kona, Hawai`i, Hawaii (pop 9,800) 180 km (110 miles) SSE of Hana, Maui, Hawaii 355 km (220 miles) SE of HONOLULU, Hawaii I asked John Burnett about feeling it. He reported it shook him around for about 10 seconds. That must have been the first "feelable" earthquake in Hilo for several years!

Kia Ora People in the Geography Department building working on Honours assignments rode out the earthquake in the 6th floor computer laboratory. Things up there are fairly secure though and no one felt any fear. Rob

0550 August 27, 2003 A magnitude 5.0 earthquake occurred at a depth of 10 km beneath the central part of Kilauea's south flank last night at 2024. The earthquake was the largest on the island since April 2, 2000; that earthquake took place in almost exactly the same place. No significant damage was done, no ground cracks or rockfalls were recognized this morning along Chain of Craters Road, and there is no change in the eruption. HVO's incoming phone system has been out since yesterday afternoon, long before the earthquake struck.

Thanks. Terry. That is the one John Burnett felt. Hilo is long overdue for a strong earthquake. I'm happy to be away from them. Rob, how appropriate for a Kiwi-quake!

High above Earth where seismic waves never reach, satellites may be able to detect earthquakes--before they strike. FULL STORY at http://science.nasa.gov/headlines/y2003/11aug_earthquakes.htm?list89800

This earthquake will have been felt strongly in Fiordland. This earthquake occurred about 40 minutes ago, but I did not feel it. Fiordland and Southland would have felt this earthquake and slight damage is possible. The earthquake is an aftershock from the August 22 event. Rob

Quite impressive for an aftershock! I hope it did not do more damage. Aftershocks are prone to do that!

Kia Ora "We will, we will rock you We will, we will rock you" That was the message from Mother Nature to coastal Japan when a magnitude 8.0 earthquake hit the region earlier today. The earthquake was 36 miles deep, which is it's saving grace, but 260 are in hospital having sustained injuries during the quake. It triggered 3ft high tsunami waves which hit Kushiro. Rob ---- Below is a report from Yahoo on the quake: Strong Quake Injures Hundreds in Japan By KENJI HALL, Associated Press Writer KUSHIRO, Japan - A magnitude 8 quake rocked Japan's northern island of Hokkaido early Friday, injuring hundreds, cutting off electricity and water to thousands, igniting a spectacular oil-tank blaze and collapsing part of an airport roof. The quake was the largest anywhere in the world this year, the U.S. Geological Survey said. Still, no deaths were immediately reported � a fact that experts attributed to sturdy Japanese buildings and the quake's location 26 miles below the ocean floor. The quake forced the evacuation of 41,000 people and left some 16,000 homes blacked out. Warnings of tsunami, or ocean waves, were briefly issued as far away as Hawaii and Alaska. The quake, which struck at 4:50 a.m., cracked roads, capsized fishing boats and caved in part of the roof of the airport in Obihiro, a city of 200,000. The temblor, centered in the Pacific about 60 miles off Hokkaido's eastern shore, was followed by several strong aftershocks and small tsunami, ocean waves. The government warned residents to avoid coastal areas, but the highest waves recorded were only about four feet. Hokkaido government official Hideki Domon said 323 people were confirmed injured as of 4 p.m., about 11 hours after the quake. Police said 22 were seriously hurt, mostly with broken bones. Japan's public broadcaster, NHK, put the injury toll at nearly 400. Kushiro, 560 miles northeast of Tokyo, was believed to be the hardest hit by the powerful quake. "The shaking went on and on," said Fumiko Okuse, who owns a liquor store wiher husband in Kushiro. "Everything was thrown out of the refrigerators and all over the floor. Juice, beer, everything." Television footage showed an office where books were knocked off shelves, and desks and computers swayed back and forth as the quake hit. Merchandise fell off store shelves and people sought shelter in schools. "It shook hard and long and I was very frightened," said Eri Takizawa, a city official in Kushiro. "We have small quakes here from time to time, but this was completely different." Black plumes of smoke and flames leapt from an oil tank in the city of Tomakomai. The fire was contained within three hours and no injuries were reported. Police said one person was injured when a local train carrying about 39 passengers derailed. Though not listed as a quake-caused fatality, a 61-year-old man cleaning up broken beer bottles on a street immediately after the quake was struck by an oncoming car and died, Hokkaido police said. A 58-year-old man also died aboard his fishing boat while trying to sail it to calm waters, but local officials said his death did not appear to have been caused by the quake. Most of the injured escaped with minor bruises and cuts caused by glass from shattered windows and objects falling off of shelves. A 70-year-old woman in this Hokkaido city, just west of Kushiro, broke her leg trying to crawl out a window. The quake had a magnitude of 8, according to Japan's Central Meteorological Agency. It was followed by an aftershock of magnitude 7. Japan is one of the world's most earthquake-prone countries. It sits atop four tectonic plates, slabs that move across the earth's surface. This month, Japan marked the 80th anniversary of a magnitude 8.3 quake that devastated Tokyo and neighboring Yokohama, killing at least 140,000 people. In January 1995, a magnitude 7.2 temblor in Kobe killed more than 6,000 people. Hokkaido is the northernmost and most sparsely populated of Japan's major islands. Sapporo, which hosted the 1972 Olympics, is the prefecture's capital. A quake and tsunami on the western side of Hokkaido killed 230 people in July 1993, most on the nearby isle of Okushiri.

Hi all This earthquake hit at 6.22AM NZST while I was in bed. I felt it strongly and there was minor damage reported in the way of loose stuff falling off shelves. Dad was in the shower and did not feel it. It has nothing to do with Fiordland's earthquake last month, but may be a result of last weeks big shake in Japan, which I will deal to shortly. Rob ---- The following earthquake has been recorded by GeoNet: Reference Number: 346668/W Universal Time: 2003 Sep 29 18:22 NZ Standard Time: 2003 Sep 30 06:22 Latitude, Longitude: 43.34�S, 173.03�E Focal Depth: 30 km Richter Magnitude: 4.9 40 km north-east of Christchurch Will have been felt in Canterbury and possibly in Marlborough.

Hi all A second earthquake (no aftershock)hit the Canterbury coast in the same place as the aforementioned one. It hit about 2.43PM local time and was strongly felt in Christchurch. No damage has been done, though it was shallower than the first. Rob ---- The following earthquake has been recorded by GeoNet: Reference Number: 2128373/G Universal Time: 2003 Oct 14 01:43 NZ Daylight Time: 2003 Oct 14 14:43 Latitude, Longitude: 43.37�S, 173.04�E Focal Depth: 12 km Richter Magnitude: 4.3 40 km north-east of Christchurch Reported felt in Christchurch

How close was this to your locale, Rob?

Hi all Thats about 35km NE of my place. I make it to be just northeast of the Ashley River mouth. Rob

Hi Rob Are your houses built to accomodate earthquakes? ie in the foundations etc The only news on earthquakes that make it to South Africa, is if there are damages to whole towns etc, like in Turkey or Japan.

Kia Ora New Zealand has a high standard of building design, and relatively low levels of corruption in the building industry. Building codes were introduced after bad earthquakes in the 1930s and 1940s where we had 5 Kobe 1995, size earthquakes or bigger over an eleven year period. New Zealand as a comparison has earthquake activity comparable with California, and shares many similarities to the state that Arnold Schwarzenegger has just been made Governor of. The country gets on average 14,000 earthquakes per annum, but of which only about 150-250 are strong enough to be felt by humans. On average here a magnitude 6 earthquake occurs in NZ every year. How familiar are you with earthquakes and plate tectonics which is the theorem behind how we see modern geology? Rob

Thanks for posting the Japan EQ information. I had seen nothing about it here.

Three (or two depending on your sources) died - so far... in a bulding collapse.

i think i felt this whilst sitting in my office...it could've been the boiler room though! kept getting cancelled messages from usgs so i had originally thought the posting was in error.

Hey Wolfie! Fantastic! I wondered how far south it had been felt. I was listening to reports on the radio but the only southern Cal report was from San Diego and was too far away to feel anything. You have joined the group!

Wolfie, I also got a cancelled notice from USGS today so I went in again and resubscribed.

actually they kept sending updates and cancelling them so i went to the website itself and found that it was not an error! now i'm watching the aftershocks..... learned that the folks working upstairs didn't feel anything!

Some folks are far more sensitive to earthquakes than others. Ask Rob. He rarely feels them. The news coverage makes Paso Robles look terrible. No two bricks standing on one another !

Alas, I thought I had sensed an earthquake some weeks ago but I forget the exact day and time. No, surely it was not this ! Just my imagination.

Neverland got hit by a quake. Arnold is on the scene at the worst devastated areas in Calif.

Do you think it is Judgement Day in Neverland? That places gives off very bad vibes for me. Arnold, no matter what you think of him, gets lots of press! We saw him on the news, too

Deadly Earthquake Jolts City in Southeast Iran By NAZILA FATHI EHRAN, Iran, Dec. 26 � A powerful earthquake rocked the ancient city of Bam in southeastern Iran today, destroying 70 to 90 percent of the city's residential areas and leaving officials fearing thousands of people had been killed or injured. Iran's government news service, the Islamic Republic News Agency, said that the earthquake's magnitude had been measured at 6.3; the United States Geological Survey put it at 6.7, though such estimates are often revised after greater study of the seismological data." The good news is that the neighboring Iranian cities of Wham, Thankew and Ma'am were all spared. Further details at: http://www.nytimes.com/2003/12/26/international/26CND-QUAKE.html It was on the CBS Evening News. They said thousands injured and dead. I'm sure we'll be talking about this one.

Frantic Hunt for Iran Quake Survivors, 20,000 Dead Dec 26, 8:46 PM (ET) By Parisa Hafezi BAM, Iran (Reuters) - Survivors of an earthquake that devastated Iran's ancient Silk Road city of Bam, killing more than 20,000 people, dug frantically with bare hands through the night early on Saturday for anyone buried alive. President Bush, who once branded Iran part of an "axis of evil" for allegedly developing weapons of mass destruction, and other world leaders rushed to offer whatever help they could to the Islamic Republic. The pre-dawn quake on Friday also injured some 50,000 people, government officials said. It measured 6.3 on the Richter scale and struck when most people were still asleep in their homes. About 70 per cent of Bam, a popular tourist spot some 600 miles southeast of the capital Tehran with an historic citadel and other centuries-old buildings, was leveled. Reuters witnesses in Bam said hundreds of corpses were bundled into trucks and the back seats of cars. Distraught relatives wailed next to bodies wrapped in blankets. more at http://news.myway.com/top/article/id/245963|top|12-26-2003::20:51|reuters.html and a whole slew of links at http://spring.net/geo/iranquake.html

Estimates put the dead at around 50,000 and between 10,000 to 30,000 injured.

Strong Quake Predicted to Hit Desert By Sept. 5 * Scientific Team's Work Gets Qualified Backing From State Panel A team of scientists that predicts that a quake with a magnitude of 6.4 or greater will occur somewhere in the Southern California desert by Sept. 5 has received a qualified endorsement from a state earthquake council. The California Earthquake Prediction Evaluation Council, a group of eight scientists selected by the state Office of Emergency Services, said it considers the new prediction by the UCLA team to be "a legitimate approach in earthquake prediction research." Still, the council pointed out in a report to the state that "the physical basis for the prediction has not been substantiated." UCLA team, headed by Vladimir Keilis-Borok, has generated interest in its prediction after it successfully forecast -- although with wide parameters in place and time -- the magnitude-6.5 San Simeon quake of Dec. 22, as well as an 8.1 quake last year off Japan's Hokkaido island. Based on its analysis, the team claims that a quake will occur somewhere within a 12,000-square-mile area east of L.A. by early September. ----- Full article (registration required) at latimes.com:

Is anyone going to watch "10.5" tomorrow night. http://nbc.com/10.5 The four-hour drama intertwines the professional and personal dilemmas of multiple characters caught up in the seismic crisis, among them Kim Delaney (search) as quake expert Samantha Hill and Beau Bridges (search) as President Paul Hollister. Schneider was expert behind the wheel of the General Lee, the souped-up car of "The Dukes of Hazzard," (search) so it's no surprise that in this miniseries, he did his own stunt work for a harrowing sequence where his vehicle sinks into the earth. Schneider plays Jonathon Kent on Smallville.

Tremor felt in Greek capital during Olympics (08-24) 07:22 PDT ATHENS, Greece (AP) A small earthquake rattled some Olympic venues Tuesday. There were no reports of injuries or damage. The Athens Geodynamic Institute said the tremor had a preliminary magnitude of 4.5 and occurred at 3:38 p.m. local time. It was centered about 42 miles northeast of Athens, 12 miles beneath the Aegean Sea. "There is no reason to panic. It was a very small quake," said Giorgos Stavrakakis, a seismologist with the Geodynamic Institute. The press table shook at the baseball venue at the Helliniko Complex near the coastline. "Like somebody was pounding the keyboard too hard," one reporter said. Other said they didn't notice anything. Venues including the Olympic Village and the 9,000-seat Ano Liossia Olympic Hall for wrestling and judo were built near the fault line and designed to withstand a potentially massive quake. International Olympic Committee took the unprecedented step of buying insurance in case the games were called off due to terrorism or natural disasters, such as earthquakes. Earthquakes are common in Greece, one of the most seismically active countries in Europe. In 1999, a 5.9-magnitude quake near Athens killed 143 people, injured about 2,000 and left thousands more homeless. An earthquake also hit Nagano, Japan, during the 1998 Winter Games, jolting athletes and spectators but causing no major damage. http://sfgate.com/cgi-bin/article.cgi?f=/news/archive/2004/08/24/sports1004EDT0340.DTL

wow, thanks for posting that Cheryl. the AM is back in Cali and i am worried about the big one supposed to hit by Sept 5 (although we all know how reliable predictions are).

There have been several sizeable quakes in Greece lately. I have heard of nothing bad happening which is a good thing. California has had two strong quakes near Parkfield where the San Andreas Fault has made life difficult before. They are warning of aftershocks. == AFTERSHOCK PROBABILITY REPORT == Southern California Seismic Network (TriNet) operated by Caltech and USGS Version 1: This report supersedes any earlier probability reports about this event. MAINSHOCK - Magnitude : 5.0 Ml Time : 29 Sep 2004 03:54:53 PM PDT : 29 Sep 2004 22:54:53 UTC Coordinates : 35 deg. 23.31 min. N, 118 deg. 37.24 min. W Event ID : 14095628 STRONG AFTERSHOCKS (Magnitude 5 and larger) - At this time (17 hours after the mainshock) the probability of a strong and possibly damaging aftershock IN THE NEXT 7 DAYS is less than 10 PERCENT. EARTHQUAKES LARGER THAN THE MAINSHOCK - Most likely, the recent mainshock will be the largest in the sequence. However, there is a small chance (APPROXIMATELY 5 TO 10 PERCENT) of an earthquake equal to or larger than this mainshock in the next 7 days. WEAK AFTERSHOCKS (Magnitude 3 to 5) - In addition, up to approximately 10 SMALL AFTERSHOCKS are expected in the same 7-DAY PERIOD and may be felt locally. This probability report is based on the statistics of aftershocks typical for California. This is not an exact prediction, but only a rough guide to expected aftershock activity. This probability report may be revised as more information becomes available. Background Information About Aftershocks Like most earthquakes, the recent earthquake is expected to be followed by numerous aftershocks. Aftershocks are additional earthquakes that occur after the mainshock and in the same geographic area. Usually, aftershocks are smaller than the mainshock, but occasionally an aftershock may be strong enough to be felt widely throughout the area and may cause additional damage, particularly to structures already weakened in the mainshock. As a rule of thumb, aftershocks of magnitude 5 and larger are considered potentially damaging. Aftershocks are most common immediately after the mainshock; their average number per day decreases rapidly as time passes. Aftershocks are most likely to be felt in the first few days after the mainshock, but may be felt weeks, months, or even years afterwards. In general, the larger the mainshock, the longer its aftershocks will be felt. Aftershocks tend to occur near the mainshock, but the exact geographic pattern of the aftershocks varies from earthquake to earthquake and is not predictable. The larger the mainshock, the larger the area of aftershocks. While there is no "hard" cutoff distance beyond which an earthquake is totally incapable of triggering an aftershock, the vast majority of aftershocks are located close to the mainshock. As a rule of thumb, a magnitude 6 mainshock may have aftershocks up to 10 to 20 miles away, while a magnitude 7 mainshock may have aftershocks as far as 30 to 50 miles away.

My relatives there did not feel it but sent the following: From CNN: Parkfield Quake Preliminary magnitude of 5.9 Tuesday, September 28, 2004 Posted: 1:50 PM EDT (1750 GMT) PARKFIELD, California (AP) -- An earthquake with a preliminary magnitude of 5.9 struck central California on Tuesday and was felt as far north as San Francisco and Sacramento, according to the U.S. Geological Survey. An aftershock of 5.0 magnitude struck four minutes later. Police said there were no immediate reports of damage or injuries. In nearby Redwood City, the quake delayed the murder trial of Scott Peterson after a juror reported feeling the tremors. Thousands of people from throughout the state reported feeling the quake. "It rattled everything hanging on the walls and the chandelier was swinging. It didn't do any damage to our house. There were two shakers, one right after the other," said Ben Brown, who lives in Paso Robles. The earthquake, which struck at 10:15 a.m. (1715 GMT) was centered 9 miles (14 kilometers) south of Parkfield and 17 miles (27 kilometers) north east of Paso Robles, scene of an earthquake that killed two people in December 2003. Parkfield, located on the San Andreas fault, is known as the earthquake capital of California.

Powerful earthquake rocks Taiwan and southern Japan Fri Oct 15, 6:19 AM ET TAIPEI (AFP) - A powerful earthquake measuring 7.0 on the Richter Scale shook Taiwan, sparkling several fires and prompting people to flee swaying high-rise buildings but causing no serious damage. Photo AFP Photo The quake led to a dozen technicians being trapped in elevators of the world's tallest building, Taipei 101, for several minutes but the 508-metre (1,666-feet) structure remained intact, passing a key safety test. The earthquake struck shortly after noon (0408 GMT) and was also felt in Japan's southern Okinawa chain, where the Meteorological Agency said it measured 6.6 on the Richter Scale. Neither Taiwan nor Okinawa reported serious injuries or damage from the tremor, which was located at sea some 109 kilometres (68 miles) off Taiwan's northeastern coast. Its focus was 58 kilometres below sea more... mms://eyenet.wm.llnwd.net/eyenet_livenews1

Great Australian Quake CANBERRA (Reuters) - Australia's southern state of Tasmania was rocked by the world's largest earthquake in three-and-a-half years when it struck under the sea half way between Australia and Antarctica on Friday, seismologists said. No injuries or damage were reported. The earthquake measuring 8.1 on the Richter scale hit near Macquarie Island in the Southern Ocean, more than 500 miles southeast of Tasmania, at about 2 a.m., said Geoscience Australia seismologist Cvetan Sinadinovski. "Usually this kind of earthquake happens every three to four years in the world, it is just a part of the dynamic cycle of the earth," Sinadinovski told Reuters. The earthquake could have caused a tsunami, but no noticeable changes in water levels had been reported in Tasmania or New Zealand, Sinadinovski said. An aftershock measuring 6.1 hit at 6.50 a.m., he said. "The last earthquake of similar magnitude in the Macquarie Rise region was in 1924. The magnitude of that earthquake was 7.5," Sinadinovski said. It is the largest earthquake to hit since more than 120 people were killed in Peru when an earthquake measuring 8.4 on the Richter scale struck less than 125 miles off the coast of the South American nation in June 2001. The Richter scale measures the magnitude of an earthquake with a reading of more than 8 regarded as a "great" earthquake that can cause serious damage over several hundred kilometers and a reading of less than 2 considered micro. Geoscience Australia said an earthquake measuring 8.6 on the Richter scale releases energy equivalent to about 10,000 atom bombs like the one that destroyed the Japanese city of Hiroshima in World War II.

Just when you thought that Australian earthquakes couldn't get any worse: JAKARTA, Indonesia (AP) - The world's most powerful earthquake in 40 years triggered massive tidal waves that slammed into villages and seaside resorts across southern and southeast Asia on Sunday, killing more than 7,000 people in six countries. Tourists, fishermen, homes and cars were swept away by walls of water up to 20 feet high that swept across the Bay of Bengal, unleashed by the 8.9-magnitude earthquake centered off the west coast of the Indonesian island of Sumatra. In Sri Lanka, 1,000 miles west of the epicenter, more than 3,000 people were killed, the country's top police official said. At least 1,870 died in Indonesia, and 1,900 along the southern coasts of India. At least 198 were confirmed dead in Thailand, 42 in Malaysia and 2 in Bangladesh. But officials expected the death toll to rise dramatically, with hundreds reported missing and all communications cut off to Sumatran towns closest to the epicenter. Hundreds of bodies were found on various beaches along India's southern state of Tamil Nadu, and more were expected to be washed in by the sea, officials said. The rush of waves brought to sudden disaster to people carrying out their daily activities on the ocean's edge: Sunbathers on the beaches of the Thai resort of Phuket were washed away; a group of 32 Indians - including 15 children - were killed while taking a ritual Hindu bath to mark the full moon day; fishing boats, with their owners clinging to their sides, were picked up by the waves and tossed away. ``All the planet is vibrating'' from the quake, said Enzo Boschi, the head of Italy's National Geophysics Institute. Speaking on SKY TG24 TV, Boschi said the quake even disturbed the Earth's rotation. more... http://my.aol.com/news/news_story.psp?type=1&cat=0100&id=2004122610130001600764

Expert Sees More Aftershocks But No Killer Quake WASHINGTON (Reuters) - Strong aftershocks from the Indonesian earthquake will be felt for "weeks and months" but more killer-magnitude tremblers and deadly tsunamis were unlikely, a geophysicist with the U.S. Geological Survey said on Wednesday. Waverly Person, a USGS director, said he anticipates repeated and at times powerful aftershocks that will spread from the epicenter of Sunday's quake in the Indian Ocean off Sumatra along a line about 600 miles long. "I don't think there's any chance of a major earthquake of (magnitude 9) but there will be continued strong aftershocks," he told Reuters from USGS headquarters in Golden, Colorado. He said USGS seismologists were aware of two quakes of magnitude 6.0 that struck on Wednesday alone. The largest aftershock at 7.5 magnitude occurred, he said, about 3.5 hours after Sunday's main quake, the world's most powerful in 40 years that set off tsunamis that barreled across the Indian Ocean before striking coastal areas in south and Southeast Asia. more... http://reuters.com/newsArticle.jhtml?type=scienceNews&storyID=7201158

but those aftershocks can produce more tsunamis?

Quake rattles Sulawesi. Sulawesi is in Indonesia, about 30 homes were damaged.

Any earthquake has the potential of creating a tsunami. Some aftershocks are stronger than the original event. Interesting data at this link gives the changes to the whole earth from the December 26th Indonesian earthquake: http://earthobservatory.nasa.gov/Newsroom/NasaNews/2005/2005011018159.html
