The U.S. Geological Survey says a minor earthquake measuring a preliminary 3.4 magnitude has rattled an area west of Dallas, Texas.
The survey's earthquake center in Golden, Colo., says the quake lasting several seconds began at 11:05 p.m. CDT Saturday and was centered about 2 miles north of Irving, Texas.
Geophysicist Randy Baldwin at the Colorado center told The Associated Press that the quake was just strong enough to likely have been felt for about 15 or 20 miles around the epicenter. He says the quake's online reporting system received no reports of any damages or injuries but there were some 1,200 responses from people who felt the quake.
Terry Austudillo posted, "heard a loud swishing sound and then the ground had a big thud. We were outside....everyone in our apartment community ran outside too. They all said it sounded like a car hit the building. It still isn't as bad as the one while I was in CA, but it's unnerving here because you don't expect it."
Penny Williams posted, "My husband and I felt the entire house move up and down, we thought something under the earth exploded."
Baldwin says smaller aftershocks are a possibility in that area in coming hours or days.
A new study by a University of Texas seismologist says that the wells used to dispose of fracking waste water are responsible for an increase in small earthquakes in Texas.
The strongest earthquake ever recorded in in the Lone Star State was in 1931 near Valentine, Texas, according to the USGS.
