When I heard this morning on NPR that Illinois had been hit by a trembler, I had to smile. I'm glad no one was hurt et cetera, but all those Midwesterners who madly prefer tornadoes over earthquakes forget that one of the most dangerous faults in the country is right in their backyard.
Recession Cone emailed me about this earlier today and linked to a fabulous USGS image I had never seen before. It's available on a couple Wikipedia articles (I'll get to those in a minute), but first, check it out:
I hadn't known about this. Seems the type of earth over thar is not quite as . . . stable . . . as over here on the far coast.
Which brings us to the New Madrid Earthquake. For those of you whose remembrance of the early 1800s is a little shaky, that was the quake that rearranged state boundaries.
Now, granted, the Hayward quake is likely to come long before the Reelfoot knocks down buildings again, but make no mistake: when Reelfoot slips, it'll be taking things down all over Missouri and Arkansas and Tennessee and Illinois.
Like RC said, "I'll take constant threat and preparation over infrequent but total devastation, thank you very much."*
Give me a California quake any day.
