Event 2008qza6


The U.S. Geological Survey has some interesting data on this morning's magnitude 5.2 earthquake in southeastern Illinois.
Thus far, their website has received 32,853 reports from all over the central United States concerning what the USGS is calling Event 2008qza6. The reports include 5 from Jonesboro, Ark., and 11 from Paragould, Ark. Our place lies between those two cities.
Here's a map showing the intensity by Zip code for the area from which reports were received. If you want to read more or add your report, here's the link to the USGS site: http://pasadena.wr.usgs.gov/shake/cus/index.html

Aftershock


The U.S. Geological Service reports a second quake - 4.1 on the Richter Scale - at 10:14 a.m. today a couple of miles from the epicenter of the pre-dawn jolt.
I thought I felt something about that time, but I dismissed it as being my imagination. Obviously, it was no big deal here.
Maybe it's a good thing to live on Crowley's Ridge when the faults slip.
Here's the website I use to keep tabs on seismic activity around here: http://folkworm.ceri.memphis.edu/recenteqs/
Oh, by the way, this is the 102nd anniversary of the 1906 earthquake that flattened San Francisco. Really. To the day.
