It’s been a week, but the earth’s not done shaking yet. Another aftershock was reported at 11:48 p.m. Monday. According to the U.S. Geological Survey, this latest rumble was a 2.6. There have been a series of aftershocks since the initial earthquake last Tuesday. Between 5:09 a.m. Saturday and 12:19 a.m. Monday morning, the U.S. Geological Survey recorded six aftershocks near the epicenter of last week’s magnitude 5.8 quake, two of them within a minute of each other. Five aftershocks came between 4:18 p.m. Sunday and 12:19 a.m. this morning. The magnitudes were small, but people reported feeling the rumbles in Northern Virginia.

This weekend’s shocks occurred at 5:02 a.m. Saturday with a magnitude 2.0, Sunday at 4:18 p.m. with a magnitude 2.2, Sunday at 9:06 p.m. with a magnitude 2.3, Sunday at 11:15 p.m. with a magnitude 2.0, Sunday at 11:16 p.m. with a magnitude 2.7 and Monday at 12:19 a.m. with a magnitude 2.2. There have been at least 20 aftershocks since last Tuesday’s quake. The largest was a magnitude 4.5. The USGS says aftershocks are common and should lessen within a few weeks.
