Friday seemed to be a day for a shift in focus, away from Tuesday’s historic earthquake and toward Saturday’s potentially historic storm. But the quake’s effects receded slowly, with at least five aftershocks felt on Thursday.
The U.S. Geological Survey reported five small earthquakes centered in Virginia on Thursday, all in the same general area as Tuesday’s stunning quake, and all apparently aftershocks from it.
The Tuesday quake near Mineral. Va., which was felt for many hundreds of miles around, had a magnitude of 5.8. The largest of Thursday’s smaller quakes was reported at 1:08 a.m. and had a magnitude of 4.5, according to the USGS.
More than 10,000 reports of that temblor were made to the USGS from hundreds of Zip codes.
On Thursday there was also a 2.5-magnitude tremor at 12:07 a.m., a 2.3 at 2:38 a.m., a 2.4 at 11:28 a.m. and a 2.6 at 7:41 p.m. All of those were reported in Northern Virginia as well as in the Mineral area. One smaller aftershock was reported Friday evening.
