More aftershocks

Though probably imperceptible, there were two more aftershocks early this morning, according to the Southeast U.S. Seismic Network. The first, a magnitude-1.6, was around 3 a.m., its epicenter about four miles south of the town of Louisa. Fifty-two minutes later, a 1.7-magnitude aftershock hit about five miles south of Mineral. Nearly seven months after Virginia’s second-leargest earthquake, a magnitude 5.8, aftershocks are still happening fairly regularly, though  less than 50 of those have been over magnitude 2–big enough to be felt. A magnitude 3.1 aftershock hit on Jan. 30. Get an up-to-date list of aftershocks here. Read my most recent story on post-quake research here.
