A second earthquake in as many weeks hit East Texas early this morning in nearly the same location.

The U.S. Geological Survey confirmed the 4.3-magnitude earthquake, which occurred about three miles outside of Timpson in Shelby County at 3:17 a.m. this morning.

KSLA.com is reporting viewers from Mount Enterprise to Bienville Parish, La., called the station reporting they felt the earthquake. Some from as far north as Whitehouse and Longview said they felt shaking this morning.

This second earthquake's epicenter was in about the same location as the 3.7-magnitude quake that happened last week. There are currently no reports of serious damage.

The cause of last week's quake and this one remain under investigation, although one meteorologist speculated it could be caused by fracking, since there is no known fault line in the area.
