Supposedly, the MS River shifted as much as 6 miles at some point. Lakes became higher and drained, smaller water courses disappeared, roads became impassable due to large crevasses, and at least one town was destroyed.<br /> Experts say repeats are due anytime. Seems the type of soil east of the Rockies makes quake effects travel farther and do more damage than the ones on the West Coast at the same Richter Scale numbers. Only equivalent quakes around the world were some in India in the 1800's !!!<br /><br />Wonder if the soil conditions are due to the Yellowstone Mega Volcano eruptions?Willnoreply@blogger.comtag:blogger.com,1999:blog-15907727.post-35630657292170029912009-08-31T14:17:40.516-04:002009-08-31T14:17:40.516-04:00alath - A new Yorktown, CV/CVS 10, an Essex-class ...alath - A new Yorktown, CV/CVS 10, an Essex-class carrier was built in 1943.

It's not that buildings and things sink down into the ground so much as the amplitude of the quake-waves can more freely accelerate, and structures can't withstand the base movement and come loose from the foundation and fall over. Old brick with no re-bar or anchoring is especially vulnerable since each brick can just about vibrate separately from the mortar and then there's nothing holding the building together but its own weight...<br />So we like to use wood for construction because it floats! :-)NotClauswitzhttps://www.blogger.com/profile/14358707844087117280noreply@blogger.comtag:blogger.com,1999:blog-15907727.post-73740249070118060552009-08-31T10:30:00.048-04:002009-08-31T10:30:00.048-04:00A major East Coast fault line is visible at at the...A major East Coast fault line is visible at at the falls along the James, Rappahannock, Potomac, and other rivers. All of DC south of Constitution Ave. is fill and will turn to sludge as did San Francisco's Marina District. Fault line extents through southern end of Manhattan Island.

The I-93 tunnel travels directly under some of the most populace parts of Boston (including the Hancock and Prudential towers) and in our shoddy engineering seismic interaction was not considered.<br /><br />So besides some asshole blowing up a truck bomb in the center of the tunnel, if one of the few dormant fault lines decides to wake up we could be in for a few very scary days in Metro-Bean-Town....Weer'd Beardhttps://www.blogger.com/profile/13528978001340070552noreply@blogger.comtag:blogger.com,1999:blog-15907727.post-16698524044256628852009-08-31T09:02:37.710-04:002009-08-31T09:02:37.710-04:00I'm no longer surprised by earthquakes anywher...I'm no longer surprised by earthquakes anywhere. A few years ago, there was a tremor in Richmond, Va that I felt in Mclean, Va (within spitting distance of DC). It felt like a truck had backed into our building. <br /><br />Earlier this year, there was a tremor in SW Va. I lived there for years and never felt an earthquake.<br /><br />We joke about Cali falling into the ocean, but it might just the East Coast that does it. :D<br /><br />ChrisAnonymousnoreply@blogger.com
