UPDATING EARTHQUAKE MAP

Why Earthquakes? Check the maps below and notice the incidence between the plate boundaries and the occurrance of Earthquakes.

We have just had 2 earth quakes on Kilauea: 3.6 and 4.5 magnitude. No tsunami was generated, and I am disappointed that I missed feeling it. I was sitting here and noticed nothing. Hmmm... More usually occur and the pattern of the eruption usually changes when we get EQ's as strong as 4.5.

There is no way to put this updating Big Island Earthquake map here so I will have to post the URL for it. http://elsei.wr.usgs.gov/results/seismic/BigIsland.html

No excitement to report before I close down. No further earthquakes. I do not know the status of the eruption, which will likely change. I will find out in the morning when the first air tour flights check things out. It is possible that the current episode will stop and a new one commence in a few days. It just depends on what has happened to the structurs of the internal plumbing. More news in the morning, Hawaiian time. Aloha! and Hugs!

We just had another earthquake which I could not feel. It was about 3.5 on the Richter scale which is just about feelable if you are very lucky, and it was on the other side of the island.

The eruption of Kilauea continues at least as vigorously as it did before the Response 8 earthquakes.

Well, I'm glad it didn't shake you up!

I always feel a little cheated when there is one I don't feel - that is, until a real bone rattler. Then, after I have anguished through whether it is ever going to stop shaking, and whether the ground is going to open up and swallow me, I promise myself never to go through another one. Then, after a while, the curious little kid in me starts to surface again... a vicious circle. Thanks for the good thoughts, though. Did you ever experience an earthquake, Ginny?

No, not yet. There have been some small tremors around here (one was centered in Littleton a couple of months ago), but I haven't felt them. I'm not complaining! I love thunder and lightning, and I don't mind hurricanes and blizzards so much (as long as I don't have to shovel or deal with floods), but I don't know if I could ever get used to earthquakes. Supposedly the Boston area is due for a big quake, which would be a disaster since most construction around here wasn't built to withstand earthquakes.

Oh great! Your BigDig will get a whole lot bigger if you have a good shaker. What is supposed to be the cause of that upcoming Big One? Are the Appalachians still pushing skyward? I can't imagine anything else...!

I can't remember what the reasoning was, but if I find out, I will be sure to post it here! From your plate pictures, we don't seem to be on the fault line between two plates, but something did create all the mountains around here. (The White Mountains in NH are part of the Appalachian chain; not sure about the Green Mountains in VT. Actually, don't the Appalachians extend up to Maine?)

Founds some old news articles at http://www.townonline.com; apparently there is a fault line around here! Wednesday, October 13, 1999 Minor earthquake reported ASSOCIATED PRESS (This Associated Press story was taken from the MetroWest Daily News.) LITTLETON -- A small earthquake shook a large area of central Massachusetts this morning, scientists reported. The brief tremor was felt shortly after 6 a.m., from Littleton and Acton to as far west as Worcester. John Ebel, director Boston College's Weston Observatory, confirmed that a minor quake did take place, and said scientists were in the process of analyzing data on the seismic activity. Police dispatchers in various towns reported hearing what they thought felt like an explosion. Others described it as sounding like a large truck, or low-flying jet. There were no reports of injuries, damage or power outages. Wednesday, October 13, 1999 Earthquake wakes residents Wednesday BOXBOROUGH - Residents of Boxborough and Littleton and surrounding towns got a rude awakening on Wednesday morning when an earthquake measuring 2.9 on the Richter scale was felt for a few seconds at about 6:09 a.m. There were no reports of damage although many reported hearing what sounded like an explosion. The force was enough to rattle dishes and startle pets. It lasted just a few seconds. Police departments in Boxborough, Littleton, Maynard and Westford received many calls from startled residents who thought perhaps there had been an explosion nearby. The strength of the quake was measured at the Weston Observatory. It was initially reported that it measured 2.4 but that was later upgraded to 2.9. There is a fault line that centers in the Boxborough-Littleton area, and temblors are quite frequent, having been registered from time to time. No after-shocks were reported.

Oh heavens, I cannot feel earthquakes below about 3.5 magnitude. Those were faint echoes of a much stronger one long ago. The Berkshires, Poconos, White mountains, Adirondaks and the rest are all foothills of the Appalachians. Mt Katahdin in Maine is the northern terminus and Mt Oglethorpe in the Carolinas is the southern terminus of that great mountain chain. Interesting about the little Boston quakes. We have several hundred of the little ones a day and no one bothers about them.

I must have slept right through that one last October. (Always said I could sleep through an earthquake... ;-) Speaking of sleep, I should be heading off to bed now... 'Night!

G'morning, all. Any new EQ's in your area of the wiggly planet? All's quiet here. I don't think you can feel a 2.9 quake unless the situations are precisely right - origin close to you and to the surface. Mostly, you hear little things like dishes and windows rattling.

Oh...when there is a big one heading for you it sounds like a freight train approaching. If you listen to a radio station closer to the epicenter than you are, the announcer will mention it and a few moments later you will feel it as the waves propagate outward.

Sounds delightful... ;-) I'm still looking for some info on predictions of "the big one" in the Boston area...

I was thinking, there were more EQs in southern Portugal when I was a child. I remember two big ones. But Marcia posted that one had taken place not far from Lisbon last summer, as I was out of the country on some vacation.

Gi, the Mediterranean end of the Iberian Peninsula is a plate boundary. I think there is no way to avoid earthquakes in Portugal. The good news is that it is most likely a sidways motion on plate edges - the least destructive (ask those living near the San Andreas fault!)

I remember when I was little my father telling me that the Appalachians were once as high as the Andes. The Appalachians are not just an eroded mountain range, they also consist of an eroded plateau to the west. You can tell this by the rock strata. In the eastern edge of the Appalachians the rock strata is angled indicating folding upward. To the western side the strata is horizontal, indicating an ancient plateau. About the Andes, the largest river in the world (largest not longest) the Amazon once flowed from east to west. The Andes were pushed up along the western edge of South America, (they're still growing), causing the river to blocked from its outlet. The Amazon became an inland sea until it broke through to the Atlantic.

Great stuff, Cheryl! Thanks for posting that. I have not studied South American geology and that was new to me. I know the Appalachians are just the remnants of very old mountains, indeed. Btw, Mauna Loa is such a large landmass that it could hold the Applachians and several other mountain chains, as well. And that is just one mountain on this island!

(MarciaH)Gi, the Mediterranean end of the Iberian Peninsula is a plate boundary. I think there is no way to avoid earthquakes in Portugal. Yes, I've seen your maps :-) What I mean is, we seem to have avoided very well for a number of years... although we are always waiting for a big one, and I made sure my building got insured against earthquake damage :-)

I think the water and the situation of that fault is what keeps the stresses from building up. Something is lubricating it and I think it is in a direction in which the current plate movement is not active. That is good news all round. May it remain thus! However, you are wise about the insurance. We have it here, as well, though most of my damage will be to picture windows. The wall and garage builder living here reinforced all load=bearing members of the house and garage when he put on the hurricane "tie-down" straps which are supposed to keep the roof on the house during a hurricane.

A question about the plate boundary at Mediterranean end of the Iberian Peninsula. At one time the Mediterranean was a dry wasteland, something like Death Valley only larger. Then there was a massive fracture in the vacinity of Gibralter, causing the Atlantic to come flooding in on the desert. Could that have been the result of an earthquake on that fault? It would have been the most enormous waterfall. One I wouldn't have wanted to be anywhere near.

Yup...either one, or the gradual eroding of the barrier between the sea and the Mediterranean basin...or all three. It was long enough ago to have left no definitive marks that I am aware of...Please, anyone?

Of course, I will hunt up the information after the softball games are over this weekend...

Two earthquakes today - 1 in East Timor and a large one of Papua New Guinea - well over 6 - 6.5 I think

It has been very active down there lately. Last week we were under Tsunami watch for a 7.1 quake in Vanuatu. The place is happening...but just what it is is the mystery. (Never did get that Mediterranean mystery solved yet...)

Earthquake in Rome today - quite large for that area.

Thanks, Anne. Looks like I'll have to go digging for that because it is not yet on domestic news or Reuters.

It was on our teletext in Oz. They are usually fairly accurate re - earthquakes cause I think they are quite interested. What they did say there was some damage in villages outside Rome - but none it seems in Rome itself - although the Pope was apologising yesterday for 2000 years of mistakes - perhaps that was enough to cause an earthquake - or should that go on geo-magnatism! Interesting huh.

...or mayhap on the Geo Mythology topic ;)

Still have seen nothing about it except that it occurred via the list from Cal Tech whose list includes all earthquakes without comment.

EARTHQUAKE - April 1, 2000 8:17 pm Hawaiian Standard time Guestimating it 5.5 magnitude More in the morning when we know what happened and any aftershocks. Near Pu'u o'o

We had a quiet night, as far as I know. This was one of the strongest Earthquakes of recent times. Its epicenter was near Pu'u O'o on Kilauea's Southeast rift. It felt like some tremendously strong had shoved the entire house very abruptly - an unusual type. Usually they shake back and forth. John reported this morning "I had dozed off and it woke me up. Certainly shook the six-story building I live in."

This is what a 7.2 earthquake did to a house here (this was the strongest I have ever felt, and that is sufficient for the rest of my life, thank you!)

At 4pm Hawaiian Standard Time we had a 4.0 eaarthquake near Halemaumau (the fire pit at the summit of Kilauea Volcano). It felt like a slight shove of my chair and creaking of the furniture. Thought someone was in the bedroom shoulder surfing again.

I just cannot imagine this!!! Maybe I should come and experience it!

I've just been asked/told that we move to California. I am upset because it means more long-term commitment to something I do not want to do with a person who is capricious enough to leave me there and move on and I'd be stuck without home or friends...I think he is crazy! Of course California has them too, EQ's) but not nice ones.

A PRELIMINARY MAGNITUDE OF 7.9 WAS COMPUTED FOR THIS EARTHQUAKE. The magnitude and location may change slightly as additional data are received from other seismograph stations. No reports of damage or casualties have been received at this time; however, this earthquake may have caused substantial damage and casualties due to its location and size. The earthquake was reported felt at Jakarta and in Singapore. An aftershock with preliminary magnitude of 6.7 was recorded about 11 minutes after this event.

The Sumatran earthquake looks more serious than first thought. Many deaths and injuries and I suppose we will have to wait for a while before we get pictures on our T.V. of the same. 7.9 is very large.

Huge, man.

Having been through a 7.2, it is truly terrifying...and Hawaii building standards are quite strict. I can only imagine the destruction and the mess in the grocery stores. I will keep you updated as I find things, and Anne, please post if you hear first!

It looks as the death rate might soar. Apparently many are beneath rubble. Death count at present 50 - with hundreds injured. Power supplies cut and causing much disruption in rescue. Will inform if I hear more.

As I feared the Earquake in Sumatra is much worse than at first though. It is now reported via the London Times - deaths are in the hundreds and injuries at least 500. Many outlying Islands have not yet been assessed. It looks as this is a bad one.

I have heard that the survivors are living outside for the time being. They are too afraid to go into any structure still standing.

http://www.lineone.net/cgi-bin/loadcontent.pl?page=/cgi-bin/drecgi/express/00/06/06/news/n2520earthquake-d.html Maggie, thank you! You could have posted it! Hundreds feared dead after huge undersea earthquake hits island The death toll from a massive undersea earthquake which hit the Indonesian island of Sumatra yesterday is expected to run into hundreds. The quake, measuring 7.9 on the Richter scale, struck at night, throwing people from their beds, flattening villages and leaving many thousands homeless across six provinces. Hundreds of aftershocks added to the damage and panic. The true scale of the disaster was slow to emerge because the quake destroyed communications in the worst-affected region of Bengkulu, a province of about 1.2 million people near the epicentre. Doctors in the provincial capital of Bengkulu town decided to treat casualties in a car park, fearing that aftershocks might bring down the state hospital. They were said to have lost a number of colleagues in the disaster and had run out of blood supplies and anaesthetic due to the sheer number of casualties. "Patients being operated on without anaesthetic could be heard screaming," said the state news agency Antara. Electricity and water supplies had been cut and most telephone lines were down. Rescuers frantically dug through the rubble of ruined buildings in search of bodies and trapped survivors. "It was very panicky. People were running everywhere and screaming after the quake hit us," said one resident. Bengkulu airport was closed because of damage to communications equipment and to the passenger terminal. Some roads to the city were said to be blocked by landslides. "Many houses have collapsed and the walls on bigger buildings have been fractured," said one survivor. "I helped to save three of my neighbours who I found had been trapped beneath the rubble of their homes." There were reports that the island of Enggano, which is about 125 miles from Bengkulu town and has a population of around 1,500, had also been badly hit. "About 90 per cent of houses on the island are damaged," said health department chief Ali Muchtar. A total of 60 people were confirmed dead last night and almost 500 were reported to have been injured, but the toll was expected to soar dramatically once rescue teams reach the rural areas. By comparison, last year's Turkish earthquake, in which 17,000 people died, was much less powerful, at 7.4 on the Richter scale. In addition, as a developing country, Indon-esia's emergency services are badly trained and very poorly equipped. Seismologists said that the tremor was centred 20 miles beneath the Indian Ocean - quite near the surface in geological terms - some 400 miles north-west of the Indonesian capital Jakarta. The quake was felt across much of the western half of the Indonesian archipelago, including Jakarta and neighbouring Singapore, where many residents fled their homes as the tremor rattled high-rise buildings. More than 260 smaller tremors were recorded through the day, frightening residents and hampering rescuers. "The quake went on for many minutes," said Bengkulu police sergeant Hariyono. "Dozens of homes have been destroyed and almost all houses and buildings in the city seem to have been damaged. People are terrified every time they feel aftershocks." Navy spokesman Rear Marshall Ontowiryo said two warships carrying food and medical supplies had been dispatched to the area. Up to 20 rescue workers from Britain's disaster relief team RAPID UK were on stand-by after the group offered to help the Indonesian authorities.Spokesman Stefan Hopkins said RAPID UK, which helped after last year's earthquakes in Turkey, could use sniffer dogs and heat-seeking equipment to find survivors. � Express Newspapers, 2000

Another huge aftershock today.

It is not unusual that aftershocks are as strong or stronger than the initial quake. That is what is frightening. The first shake loosens everything. The later ones make what is loose crumble, fall down and bury the unwary who remain inside. That is why no one will go back home after a strong one! Just as the 4 or so wave in a Tsunami does the most damage, so it is with earth quakes.

Strong Quake Rocks Taiwan TAIPEI (Reuters) - An earthquake rocked Taiwan early on Sunday, injuring more than 10 people, but there were no immediate reports of major damage, seismologists and media said. Semiconductor makers in northern Hsinchu Science Park, one of the world's top microchip production bases and a motor of Taiwan's export economy, were unaffected, the state-funded Central News Agency (CNA) said. The Central Weather Bureau said the quake, registering 6.7 on the Richter scale, occurred at 2:23 a.m. and was felt throughout the island. It was centered 29 miles north of the sparsely populated Jade Mountain in central Taiwan. Operations at Taiwan Semiconductor Manufacturing Co and United Microelectronics Corp were normal as there were no power outages at the Hsinchu Science Park Taiwan's Silicon Valley, CNA said. A killer quake last September caused widespread power outages islandwide, disrupting production at TSMC, Taiwan's leading made-to-order foundry chipmaker. On Sunday, six aftershocks measuring between 4.3 and 5.1 on the Richter scale jolted the island in the next two hours, the weather bureau said. More than 10 people were rushed to hospital after either suffering bone fractures or being cut by broken glass when they fled their homes in Puli in the central county of Nantou, independent cable broadcaster TVBS said. Three people were injured by falling rocks near Puli, CNA said. Many residents in the area were afraid to return to their homes and wandered in the streets, TVBS said. One person jumped from his second-floor home in central Taiwan and was slightly injured, the broadcaster said. Puli, close to the epicenter of the devastating September 21 earthquake measuring 7.6 on the Richter scale, suffered outages. Last year's killer quake and a series of strong aftershocks killed 2,400 people and wrecked 52,000 buildings on the island. Taiwan lies on a seismically active stretch of the Pacific basin and earthquakes occur frequently.

The following is a release by the United States Geological Survey,National Earthquake Information Center: A strong earthquake occurred IN ICELAND, about 55 miles (90 km) east-southeast of Reykjavik at 9:41 AM MDT today, Jun 17, 2000 (3:41 PM local time in Iceland). A PRELIMINARY MAGNITUDE OF 6.6 WAS COMPUTED FOR THIS EARTHQUAKE. The magnitude and location may change slightly as additional data are received from other seismograph stations. There have been some reports of damaged roads in the area. The earthquake was felt in large parts of Iceland. This is the largest earthquake in this general area since a magnitude 7.0 earthquake on May 6,1912.

Would it be to do with vulcanism. After all Sertsey was part of a volcanic eruption some years ago. I just wondered if this was a pre-a volcanic eruption?

Iceland sits astride the Mid-Atlantic Rift which is where the ocean is spreading as the Pacific gets smaller. As the crust spreads and ruptures new magma rises and eventually surfaces into a new island - which is Surtsey's story. The mid-aisan problem is a puzzle since no known fractures exist there. You can bet the latest technology and the brightest grad students are rushing there to figure out what is happening. I'll let you know as soon I hear more. NEWEST EARTHQUAKE REPORT: World Data Center A for Seismology The following is a release by the United States Geological Survey, National Earthquake Information Center: A major earthquake occurred IN THE SOUTH INDIAN OCEAN, about 110 (180 km) south-southeast of the Cocos Islands or about 820 miles (1320 km) southwest of Jakarta, Indonesia at 8:44 AM MDT today, Jun 18, 2000 (9:14 PM local time in Cocos Islands). A PRELIMINARY MAGNITUDE OF 7.5 WAS COMPUTED FOR THIS EARTHQUAKE. The magnitude and location may change slightly as additional data are received from other seismograph stations. This earthquake is located in a remote area and no damage or casualties are expected. However, this is believed to be the largest earthquake on record in the area.

Cocos Islands being Australian is a little more explicit, although I find it hard to fathom. (excuse pun). How can a 7.2 earthquake not cause any damage - the police apparently reported it was a very mild quake. Was it very deep seated or what. Also is it strange to have such a quake in the Indian Ocean - I don't think I have noticed such a one before.

I went through a 6.8 and 7.2 magnitude. The larger one did less damage because the epicenter was in the mantle beneatth 22,000 ft of water and the crustal plate. We all shook and glassware fell off the shelves but no buildings fell down. The 6.8 one was shallower and was a nightmare to ride out!

Thank you. There was a minor quake in Western Australia today - not sure if it had anything to do with the Cocos Islands. Also they were expect tsinami to hit with 2 metre waves in North Western Australia which did not eventuate.

Thank goodness for the non-tsunami events. Thanks!

A PRELIMINARY MAGNITUDE OF 6.6 WAS COMPUTED FOR THIS EARTHQUAKE. The magnitude and location may change slightly as additional data are received from other seismograph stations. This earthquake occurred in the same general area as a magnitude 6.6 earthquake on June 17, 2000. There have been some reports of power outages in the epicentral area. This earthquake was felt strongly in Reykjavik and was felt throughout Iceland. There have been no reports of damage or casualties at this time.

Marcia is that the first or second earthquake felt in Iceland - the cracks in the roads and fields were horrific as was the damage to houses - on our news this morning.

Yes, and on ours. It looked all to familiar! Wednesday June 21 8:41 AM ET Earthquake Shakes Southwest Iceland REYKJAVIK, Iceland (AP) - Many Icelanders awoke with a jolt Wednesday as an earthquake shook the southwestern part of the island, knocking down a dozen houses but causing no serious injuries. The Meteorological Institute said the temblor had a magnitude of 6.6 and struck at 12:52 a.m. local time. The epicenter was close to Hestfjall, in the Grimsnes area of south Iceland. The quake apparently followed an earthquake of similar magnitude on Saturday, which caused some electrical and water outages. A bridge over the Thjorsa was temporarily closed for inspection but reopened Wednesday morning. Hot water pipes broke between the town of Selfoss and the villages of Eyrarbakki and Stokkseyri. Civil Defense officials said about a dozen houses were destroyed and twice as many seriously damaged in the Grimsnes area, a popular place for summer cottages. The U.S. Geological Survey in Washington also registered the magnitude at 6.6, and said the quake occurred 6.2 miles below ground. Before the past two quakes, the last event of that size in Iceland took place in 1910. Iceland, where there are many active volcanoes, frequently experiences minor earthquakes.

Welcome and aloha, Masoud...please post something!

i am a begineer in this Site!!

Welcome! You did just fine. Tell us what you are studying...You are the first real person who knows about these things. We are honored!

****************************** Apoyo Volcano, Nicaragua ****************************** Destructive Earthquake at Laguna de Apoyo, Nicaragua --------------------------------------------------------------- Today, 6 of July, at 1:30 PM local time (19:30 GMT) a magnitude 5.4 earthquake occurred near the northern rim of Laguna de Apoyo (Apoyo volcano), about 32 km southeast of Managua, at 11.96 N 86.02 E, focal depth less than 1 km. The shock was felt widely in the Pacific part of Nicaragua, there are also reports from the Atlanic region. The event was felt strong in Managua (Intensidad Mercalli V-VI), very strong (VI) in the city of Masaya (5 km to the epicenter) and was destructive in the vicinities of Laguna de Apoyo. There the maximum intensity might have reached VII or VIII. Numerous landslides occurred in the crater walls, surface faulting was observed, trees and electricity lines broke, total and partial destruction of houses and electricity lines occurred. The road to the village at the beach of Laguna de Apoyo was interrupted by landslides. About 70 people were injured and four children were killed due to collapsing walls or roofs of their houses. At Masaya volcano, at about 8 km from the epicenter, minor collapses of the walls of Santiago crater occurred. No changes in the degassing activity of the volcano were observed. In Masaya, one of the mayor Nicaraguan towns, houses, walls and other constructions were damaged. Electricity and telephone networks were affected in the vicinities of Laguna de Apoyo. The cellular telephon network had a mayor blackout after the earthquake. One minute before the earthquake a precursor occurred; after the main shock a series of aftershocks was recorded by the Nicaraguan seismic network, many of them beeing felt in Masaya and even Managua. This activity is still going on. Laguna de Apoyo is a volcanic crater of 8 km diameter which was formed by large volcanic explosions several thousand years ago. No volcanic activity is known in historical times. The recent seismic activity (hopefully) has no volcanic background but is caused by mayor tectonic faults trending NNW at the northern rim of the crater. The earthquake was one of the strongest seismic events in the Nicaraguan volcanic chain in the last decades. and is comparable with the Managua earthquake 1972 (10,000 deaths), the earthquake of Rivas 1985 (minor damages), and the earthquake in the Fonseca Bay 1999. It is expected that aftershock activity continues in the next days and weeks. INETER maintains a rather dense network of seismic stations in the area between the cities of Managua, Masaya and Granada, one station is situated in the epicenter area of the Apoyo earthquake. There remain hazards from the aftershock activity, especially due to the possibility of other landslides. Government, Civil Defense, local Fire Departments and other organizations were very active attempting first aid. Local people are prepared to sleep outside their houses during the next nights, many families left their homes, temporarily. Others, especially children, were evacuated to Masaya or Granada city.

Japan has copped it today, earthquake, typhoon and volcano blew up. My opinion perhaps they should consider not killing whales. Someone indeed is giving warning.

Anne, I talked last night with a Tanzania guy studying in Okinawa. He reported only a whole lot of rain. Now I awake to this new. I guess I had better check to see what David has forwarded about this latest disaster. Yup! Stop the whale killing would definitely be a great idea.

Is that unusual to have three earthquakes at the exact same depth?

I think so. This service gives me the EQ info as soon as it is available and is often not adjusted for accuracy yet (by correlating the data from other seismograph stations). 5.2 on 07/29/2000 15:54:20 GMT ----- ANDREANOF ISL, ALEUTIAN IS. 82.3 km deep 51.32N 179.42W Source: GLDFSCR Quality: A Type: Mb 5.2 on 07/29/2000 09:54:41 GMT ----- KAMCHATKA PENINSULA, RUSSIA 164.2 km deep 53.05N 157.53E Source: GLDFSCR Quality: A Type: Mb 5.0 on 07/29/2000 12:09:54 GMT ----- SOUTH OF PANAMA 10.0 km deep 7.23N 79.38W Source: GLDFSCR Quality: B Type: Mb 5.0 on 07/29/2000 11:54:47 GMT ----- SOUTH INDIAN OCEAN 10.0 km deep 13.85S 97.28E Source: GLDFSCR Quality: B Type: Mb date: Sat Jul 29 17:01:40 GMT 2000
