Few folks in this country know or understands that the largest earthquake recorded in modern history occurred in this same region near New Madrid. Called the new Madrid fault zone it had an earthquake measuring (by estimate) 7.9 to 8.0 on the Ricther scale.
Because the sedimentary layers are well-established and far ranging in this area the earthquakes damage and effects are much further transmitted than similar sized earthquakes in California. This compares the damage zone (structural building damage in red) and reach of the zone of shaking and felt tremors (yellow) from an 1895 earthquake in the New Madrid zone to the Northridge quake in LA in 1994.
Also if Obama beats Hillary in Indiana's primary expect there to be a whole lotta shakin' going on then too.
What? I'm just sayin'
Strong aftershock reported in Illinois
WEST SALEM, Ill. (AP) - The U.S. Geological Survey says it has recorded one of the strongest aftershock so far from Friday's Illinois earthquake.
Geologists say the temblor just before 12:40 a.m. Monday registered at 4.5 magnitude at its epicenter about 5 miles northwest of Mount Carmel. The location is in the same area as Friday's early-morning 5.2-magnitude earthquake, which was followed by a 4.5 magnitude aftershock about 5 1/2 hours later.
The Monday morning aftershock was at least the 15th since Friday's quake
