GREER, S.C. - A magnitude 3.1 earthquake shook parts of Western North Carolina and the Upstate on Friday morning, shaking houses, but not causing any reported damage. The phones at WYFF News 4 were ringing off the hook Friday morning, with calls from people wondering what had happened.
A loud noise many people heard at the beginning of the quake made people think it might have been something other than an earthquake, but experts say it's not uncommon for there to be a loud noise at the beginning or end of a quake.
According to the U.S. Geological Survey, the quake was centered just east of Columbus, N.C., and northeast of Landrum, S.C.
The quake occurred at 6:07 a.m. about 3 miles below the surface, the USGS said.
