If you felt something shake you up in the state of Virginia over the weekend it may have been a result of Four earthquakes that jarred areas of Louisa County, Va. Sunday and Monday?, but they were very small, varying in magnitude between 1.2 and 2.2. The first and largest of the four quakes struck at 9:39 p.m. Saturday night. The U.S. Geological Survey (USGS) received a handful of reports from witnesses who observed weak shaking from the magnitude 2.2 tremor, mainly in Louisa and Orange Counties.
The other three – magnitude 1.3, 1.2, and 1.5, hit in a four hour span Sunday night at 9:08, 10:58, and 11:40 p.m. They were too weak to be felt. The epicenter of these minor tremors was near Mineral, Va., the site of the 5.8-magnitude quake August 23, 2011, Virginia’s second largest on record. “[These were] close to the Mineral aftershock sequence, so they are probably continuing aftershocks,” Martin Chapman, director of the Virginia Tech Seismological Observatory, told InsideNova.
