One of the largest aftershocks to hit Virginia since the August 23 earthquake rocked the state Thursday morning.
According to the United States Geological Survey (USGS), at 5:09 a.m. Thursday morning, a 3.4 magnitude aftershock struck 4 miles southeast of Mineral, Virginia, the epicenter of the initial quake.
The aftershock on Thursday struck at the relatively shallow depth of 3 miles.
The town of Mineral is located in Louisa County, roughly 36 miles northwest of Richmond, Virginia.
Still shaken up from last Tuesday's 5.8-magnitude earthquake, Mineral has experienced more than 20 aftershocks ranging from 4.5 to 1.8 - including two aftershocks on Wednesday that registered 1.8 and 2.1 respectively.
While the Louisa County Sherriff's Office said there have been no reports of damages, Thursday's quake prompted authorities to go back and re-examine some buildings that had already been inspected after the initial quake, according to Charlottesville, Virginia's The Daily Progress.
The initial blast was felt as far north as Toronto, Canada, sending shockwaves up and down the East Coast and causing businesses to evacuate buildings in both Washington D.C. and New York City. In Washington D.C., the White House and Pentagon were evacuated and the National Cathedral and Washington Monument remain closed due to damages sustained during the earthquake.
