A 3.0-magnitude earthquake centered 2 miles south of Springtown in northeast Parker County did no damage but was felt about 1:54 p.m. by people in Springtown, Azle and Weatherford, as well as Boyd in Wise County, an official with the U.S. Geological Survey said.“I have 10 email reports from people feeling it in the area,” geophysicist John Bellini said. “People will feel this size earthquake if they’re awake, and maybe hear a little boom. But it really needs to be a 4.5 to 5 to cause damage.”Several earthquakes have occurred in the same general area since Tuesday, Bellini said.The first, a 2.6-magnitude quake about 2 miles east of Reno, was at 8:30 p.m. Tuesday and was followed at 10 p.m. by an aftershock.A 2.9-magnitude quake was felt at 10:30 p.m. Thursday, about 5 miles south-southwest of Springtown.Saturday’s quake likely resulted from movement of a 100-foot fault, Bellini said. Injection wells used by gas-drilling companies can lubricate faults, but out of the thousands of such wells in the U.S., only about half a dozen have been linked to induced seismicity (the rate of earthquakes in an area), Bellini said.The Parker County Sheriff’s Department received no calls Saturday reporting an earthquake or damage from one, said spokeswoman Danie Huffman. This report includes material from the Star-Telegram archives.
