Another small aftershock
Even if you were awake at 4:36 in the wee hours this morning, you probably wouldn’t have felt it, but it was another aftershock from last summer’s magnitude-5.8 earthquake. The magnitude-1.7 shock was reported by the U.S. Geological Survey, centered about seven miles southwest of Mineral. The last aftershock hit around 1:04 a.m. on April 26, also a magnitude 1.7. That one was in the same area, about eight miles southwest of Mineral. Before that, there were two on March 7–a magnitude-1.6 at around 3 a.m., its epicenter about four miles south of the town of Louisa, and 52 minutes later, a 1.7-magnitude aftershock hit about five miles south of Mineral. USGS scientists say the aftershocks are helping them to better define the fault area that caused the earthquake last Aug. 23. There have been over 50 aftershocks over magnitude 2.0 since the earthquake, according to USGS.
