[Rot 911]

Very interesting article. Even those of us in flyover country aren't immune to earthquakes. The New Madrid fault line (abut 150 miles southeast of where I live) has the same potential for devastation as Cascadia and has demonstrated its power in the past:

1811–12 earthquake series[edit]

Main article: 1811–12 New Madrid earthquakes
December 16, 1811, 0815 UTC (2:15 a.m.); (M ~7.2 – 8.2[9]) epicenter in northeast Arkansas; it caused only slight damage to man-made structures, mainly because of the sparse population in the epicentral area. The future location of Memphis, Tennessee was shaken at Mercalli level nine intensity. A seismic seiche propagated upriver and Little Prairie was destroyed by liquefaction.[10] Local uplifts of the ground and water waves moving upstream gave the illusion that the river was flowing backwards.[9]
At New Madrid, trees were knocked down and riverbanks collapsed. This event shook windows and furniture in Washington, D.C., rang bells in Richmond, Virginia, sloshed well water and shook houses in Charleston, South Carolina, and knocked plaster off of houses in Columbia, South Carolina. In Jefferson, Indiana, furniture moved and in Lebanon, Ohio, residents fled their homes. Observers in Herculaneum, Missouri, called it "severe" and said it had a duration of 10–12 minutes.[11]Aftershocks were felt every six to ten minutes, a total of 27, in New Madrid until what was called the Daylight Shock, which was of the same intensity as the first. Many of these were also felt throughout the eastern US, though with less intensity than the initial earthquake.[11]
