Some residents in Louisa County felt another aftershock Wednesday morning.
A 2.3 magnitude earthquake struck just after 7:00 AM, according to the US Geological Survey.
The epicenter was six miles southwest of Louisa.
Wednesday’s earthquake was an aftershock from the magnitude 5.8 earthquake of August 23, 2011. That previous earthquake startled tens of millions of people in the eastern U.S. and southeastern Canada, and damaged schools and houses in the epicentral area.
Since the 2011 earthquake, more than 450 aftershocks have been recorded.
More than 50 of these aftershocks were large enough to be felt, and 38 were the size of today's earthquake, or larger.
Scientists expect that these aftershocks will continue for many months.
