IMHO the most benign weather in the US is the Mid-Atlantic, you're totally correct. We NORMALLY don't have to worry about a 9.0 earthquake or having the Delmarva Peninsula fall into the ocean. Hurricanes tend to be tropical storms by the time they get here, and even though we had Isabel in 2003(?) and it tore up the Tidewater area, it was by no means a Charlie or a Katrina. The Mid West has the worst tornadoes on the face of the earth. New England has Nor'Easters and weather extremes (the highest winds on the face of the planet were recorded atop Mt Washington), and the entire South has tornadoes, floods, hurricanes, ad nauseam. Even violent earthquakes. The Emergency Management doomsday scenario is not San Andreas Fault, but the New Madrid Fault, site of the most violent earthquakes in North America from 1811-14. The subsedence of the earth changed the course of the Mississippi and can still be seen today. The worst part of the New Madrid Plate is that as we haven't seen a major earthquake in that area for 200 years, there has been very little retrofitting and therefore another 8.0 would be the nightmare of our history. New Madrid is both the Mid West and the South, as the fault goes from Illinois clear down to Memphis and even down into Arkansas and Mississippi. Over 15 million people live there. It would be catastrophic. The other thing is that whereas the California plates are primarily on rock and granite, and the earthquake damage areas tend to be constrained, the New Madrid fault is below sedimentary fluvial soils that would liquefy and even expand the destructive range of the earthquake. The 1811 earthquake cracked chimneys in Boston, even trans-Appalachian. The public domain USGS picture below shows the point of roughly equivalently strong earthquakes and their damage potential in CA and the MS valley. Food for thought....
Anyway, I'm glad to live where we live.
