NEW MADRID

Interesting that as the talks in Iran are going into 'double overtime,' the USGS should release this report on what kind of damage would come out of the New Madrid Seismic Zone should earthquakes the magnitude of which struck in 1811-1812 (in the 8.0 - 8.3 range) strike the zone again.

What appears to be different about this map than previous studies of this zone is Oklahoma. In 1811-1812, Oklahoma was not inhabited by white settlers yet, so there were virtually no reports from anyone in that area who reported feeling the effects of those quakes. Different story along the East Coast, where, in Boston, history tells us the New Madrid quakes shook church bells, and citizens from Maine to South Carolina reported feeling the ground shaking.

Late last night, a 4.0 quake, with an epicenter at Steele, MO, was felt in Memphis, Tennessee, and as far north as Carbondale, Illinois.
