Six aftershocks - so far

That mid-morning jolt was actually the sixth aftershock from the 4:37 a.m. magnitude 5.2 earthquake, according to reports from seismologists.

Here's the magnitude, time and epicenter location of this morning's earthquake activity in southeastern Illinois:
4.6 10:14:16 - 8 mi E of West Salem, IL
2.6 06:55:57 - 6 mi NW of Mount Carmel, IL
2.2 05:46:24 - 4 mi NNE of Bellmont, IL
2.4 05:36:33 - 6 mi NNE of Bellmont, IL
2.5 05:15:35 - 3 mi S of Noble, IL
2.5 05:03:59 - 4 mi NW of Mount Carmel, IL
5.2 04:37:00 - 6 mi NW of Mount Carmel, IL

The ones in the magnitude 2 range are called micro-earthquakes and usually go unnoticed by most people.
BTW, the Associated Press is behind the curve here. They're reporting only four aftershocks, concluding with the 4.6 temblor at 10:14 a.m.
Hah!

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.

Oh, by the way, this is the 102nd anniversary of the 1906 earthquake that flattened San Francisco. Really. To the day.

We slept through it

You'd think we would notice a magnitude 5.2 earthquake with an epicenter only 150 miles to our northeast.
But nope, we slept right through it.
I think most people who were awake around here at 4:36:59 a.m. CDT felt it, put it passed unnoticed at our house.
No cracks in tile or pavement, nothing falling off of shelves, nothing noticeable at all.
