Are Arkansas quakes about to intensify?

February 28, 2011 (Greenbrier, AR) — The US Geological Society confirms as a 4.7 earthquake struck near Greenbrier Sunday night just after 11, followed by a 3.8 aftershock. KOLR/KSFX’s Facebook page was filled with reports from people feeling the quake as far as Ava, West Plains, and Reeds Spring, Missouri, as well as Calico Rock, Mountain View, and Flippin, Arkansas. “The couch I was sitting on felt like it was moving back and forth and the decor on the walls rattled,” says Erica Davis of West Plains. “In Hollister, my floor rumbled like crazy and my monitor was jumping,” says Judy Lockhart. “Strongest I’ve ever felt. That was creepy!” The quake struck in the midst of severe weather. Tornado and thunderstorm warnings were issued across northern Arkansas and southwest Missouri Sunday evening as a cold front moved in. “My pictures on the wall rattled in two different waves about 10 seconds apart, so I shut off the TV thinking I was listening for a tornado,” says Amber Hicks of Nixa. “Pretty neat if you ask me, not so much for the folks in Arkansas!” Shelia Maxwell, the Director of Faulkner County’s Office of Emergency Management, says that there have been no reports of damages associated with the earthquake. “We all got a pretty good shake, but no reports of damage at this time.” –Ozark First
