Turtle Posted March 30, 2009 Report Share Posted March 30, 2009 Lot's of earthquake activity of late. Right now it is Alaska going to town, earlier in the week a swarm in California and the week before a great-quake and shock aftershock series near Tonga.

Turtle Posted January 13, 2010 Report Share Posted January 13, 2010 we started the op with the question of earthquake prediction so back to the touchstone. after the off-shore callifornia series last post, i would have (did in my head. ) predicted some off-shore activity up my way along the oregon or washington coast. i would have been (was) wrong. but only in so much as location & size. :doh: still, it's only recently the idea that a quake or quake series in one spot can trigger another, and what we have here even i'm not suggesting is such a case as it is so far removed. no one saw this one coming. :lol: [quote name=JONATHAN M.

Buffy Posted January 13, 2010 Report Share Posted January 13, 2010 The video and pics coming in from Haiti are horrific. It's quite a reminder of what life is like in a conservative "all government is evil and useless" Nirvana where there are no government building codes and no emergency services. Gosh I really want to live in a country like that.... Also a reminder to check and rotate the supplies in your earthquake kits if you live in shakeyland, and consider contributing to the Red Cross or other (legitimate!) relief agencies who'll be responding (some of whom have people who are apparently trapped in the rubble because of those wonderfully unsupervised building contractors...).

andrewflintoff Posted January 13, 2010 Report Share Posted January 13, 2010 The earthquakes in that are are probably low on the Richter scale, that is they are very small. The plate movement in that area is most likely divergent as these type of plate margins produce the most gentle earthquakes, thus the earthquakes in that area are not violent and do not cause much damage Quote Link to comment Share on other sites More sharing options...

Gosh I really want to live in a country like that.... indeed. while you cally folks are more "on-top-of" earthquake preparedness, much of the nation is not. had this 7.0 quake struck near many US cities, I expect we'd see similar damage. new madrid fault system comes to mind. moreover, we in the us are not as up to date as you imply. http://pubs.usgs.gov/fs/2000/fs075-00/fs075-00.pdfSeismic monitoring is vital to meet the Nation’s needs for timely and accurate information used in reducing the loss of life and property from earthquakes, tsunamis, and volcanic eruptions.An Advanced National Seismic System is needed to organize, modernize, standardize, and stabilize seismic monitoring in the United States. Most existing systems monitor either weak seismic motions or strong ground shaking, but not both. Modern seismographs can record both weak motions and strong motions onscale with high accuracy. By bringing this information in through a central computer with modern high-speed telecommunications, it becomes an important tool for emergency response. it is advanced monitoring systems that will allow us to predict quakes with any accuracy.

Maryland Geological Survey: Earthquakes in MarylandThe last earthquake to cause appreciable damage in the eastern United States occurred in 1886 near Charleston, South Carolina. It had an estimated magnitude of 6.5-7, an intensity of X, and was felt over an area of two million square miles. Even in Maryland, the felt intensity from this earthquake was IV to V. Perhaps the greatest seismic event ever to occur in North America in historic times was a series of earthquakes that shook the mid-continent around New Madrid, Missouri in the winter of 1811-1812. Estimates of the magnitude range as high as 8.7; estimated maximum intensity was XII; and the felt area, which included Maryland, was 2 million square miles. Other damaging earthquakes in the eastern U.S. include an intensity VIII event near Boston in 1755 and intensity VI events near New York City in 1737 and 1884. ... ~ a stitch in time saves nine. ~ unatesttedReady.gov - Prepare.

There is a link Google LatLong: Haiti imagery layer now available which is viewable on Google earth or on Google Maps. The vicinity of the destroyed National Palace. The streets all around the city are full of people. Clicking back and forth between the current and the 2008 imagery, shows the extent of the devastation throughout the city, though ground level imagery from news organizations really shows how horrible it is.

Turtle Posted January 14, 2010 Report Share Posted January 14, 2010 Sad. I've been following this in the news. yeah; it is sad. speaking of which: U.S. evangelical minister Pat Robertson said the devastating earthquake in Haiti could have occurred because of a long-ago pact with the devil.

Turtle Posted January 15, 2010 Report Share Posted January 15, 2010 going back to the california offshore series, there is a viral video of a dog reacting to "something" just seconds before the initial quake hits. YouTube - Dog's Sixth Sense - 2010 Quake http://www.youtube.com/watch?v=OWAhuln8ZeQ to me it looks like the dog got a static shock. he feels something down by his right leg, the charge building, and when he brings his muzzle down to check it, zap! :naughty: this put me in mind of our old discussion of piezoelectric earth effects. :D >> Piezoelectric earth US quake of the day; 17 miles from oklahoma city:Magnitude 3.3 - OKLAHOMA Quote Link to comment Share on other sites More sharing options...
