I felt my first earthquake early Sunday morning. September 11th.
I was not far from San Angelo, and felt the truck move, it actually shook, for about 2 seconds....I had been up for about 30 minutes but was still relaxing in the sleeper, checking email, news about the anniversary of September 11, and recent tweets on my iPad.
Normally when you feel that in a stationary truck cab, its either a gust of wind, or maybe a heavily loaded truck that rolls by on the highway. I heard an hour later it was an earthquake in Snyder. Magnitude 4.4 on the scale. It's a sparsely populated area, and the suspicion is that the oil and gas operations in the area are causing it. Where have we heard THAT before?
There have been several aftershocks, and in fact, in the last few years, they have had a number of minor tremblors in the area.

This was centered in a county named appropriately, Scurry County.
