Earthquake shakes North Texas

IRVING, Texas -- A magnitude-3.3 earthquake has shaken North Texas.

The U.S. Geological Survey said the quake occurred about 9:15 p.m. Saturday and was centered about 2 miles beneath east Irving, 6 miles northwest of Dallas.

CBS Dallas-Fort Worth reported the quake was felt over a wide area, likely because it was relatively shallow. It was the strongest earthquake to hit the Dallas area since September of 2009, which has experienced several temblors since the summer.

James McLellan, a public information officer for the Irving Police Department, told CBS News there were no reports of damage or injuries.

Small earthquakes have become more common recently in Texas and Oklahoma. Last month, the Texas Railroad Commission amended rules for disposal well operators amid concerns that high-pressure injections can trigger earthquakes.

Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and that damage is not likely as a result of quakes below magnitude 4.0.
