LOUISA, Va. (AP) — Aftershocks from last summer's magnitude-5.8 earthquake continue to rattle Virginia.

The U.S. Geological Survey says a magnitude-3.2 aftershock occurred at 6:39 p.m. Monday 10 miles south-southeast of Mineral, the epicenter of the Aug. 23 earthquake.

Dominion says in a report to federal regulators that the aftershock didn't affect operations at its North Anna Nuclear Station and there was no damage. Both of the plant's reactors remain at 100 percent power.

Seismologists tell media outlets that aftershocks can continue for months after an earthquake.
