The U.S. Geological Survey is reporting a 4.7-magnitude earthquake hit in Oklahoma on Monday night.
Oklahoma experienced more shaking Monday, just days after the state's largest recorded earthquake.
The U.S. Geological Survey is reporting a 4.7-magnitude earthquake hit at about 8:47 p.m. The epicenter was near Prague, Okla., at an estimated depth of 3.1 miles.
Several North Texans said they felt the quake in areas as varied as Dallas, Allen and Euless.
A 5.6-magnitude tremor and a series of smaller aftershocks struck Central Oklahoma over the weekend.
Hundreds of North Texans reported feeling the ground or their homes shake after that quake, which was originally reported as a 5.3 magnitude and then bumped up.
Oklahoma has seen a dramatic increase in seismic activity in the past two years. It typically had about 50 earthquakes a year until 2009, but more than 1,000 shook the state last year. Most of the tremors were small.
So far, experts have no explanation for the increase.
