The 3.4-magnitude aftershock hit the Louisa County town, 81 miles southeast of Washington, at 5:09 a.m., according to the U.S. Geological Survey.

This is the latest of more than 20 aftershocks following last week’s quake. Thursday morning’s tremor is the second strongest of the series — the strongest hit last Thursday and clocked in at magnitude of 4.5. It was preceded by three aftershocks of magnitude 3.1, 2.1 and 1.8 Wednesday.

There have been no reports of damage or injuries as a result of Thursday’s aftershock.
