3.7 earthquake hits East Texas

TIMPSON, Texas (AP) - Authorities say a 3.7 earthquake has shaken parts of East Texas.

The U.S. Geological Survey says the tremor struck Thursday morning in an area between Garrison and Timpson, about 24 miles northeast of Nacogdoches.

Gary Patterson of the U.S. Geological Survey in Memphis says survey geologists are baffled by the event. He says, "It's not where we normally see earthquakes in Texas."

Timpson City Secretary Tanya Windham says she initially thought a nearby train had derailed and it "shook the whole city hall" for about 15 to 20 seconds.

Nacogdoches County Sheriff Thomas Kerss says the shifting earth cracked concrete and brick support columns and window panes but did no significant damage.

There were no reported injuries.
