Original: Days after a shook the East Coast, a fifth aftershock hit Virginia.

A 4.5 magnitude aftershock occurred around 1:07 a.m. Thursday, according to the United States Geological Survey.

Four other aftershocks occurred within hours of the Tuesday afternoon earthquake: a 2.8 at 2:46 p.m., a 2.2 at 3:20 p.m., and a 4.2 at 8:04 p.m. that day, and a 3.4 at 12:45 a.m. Wednesday morning.

All five aftershocks, as well as the initial earthquake, occurred near Mineral — about 35 miles northwest of Richmond and 84 miles southwest of Washington, D.C.

This article has been corrected to show this is the fifth aftershock since Tuesday's earthquake.
