Five more aftershocks were recorded during the overnight hours of Sunday into Monday, bringing the total number of aftershocks to 16, confirmed Jessica Sigala, a USGS seismologist.

“There may have been more than 16, but the others would have been too small for us to locate,” Sigala said Monday. Sigala said the 16 recorded aftershocks have registered a 2.0-magnitude or higher; three of them clocked in at 3.0 or higher, with one 4.5 magnitude aftershock hitting the area Thursday.

Four of the aftershocks — a magnitude 2.2 at 4:18 p.m. Sunday, a 2.3 at 9:06 p.m., a 2.0 at 11:15 p.m. and a 2.7 at 11:16 p.m. — were centered near Louisa, Va.

According to Sigala, 175 people reported feeling the largest of Sunday night’s aftershocks, the 2.7 that occurred 11:16 p.m.

The last aftershock occurred seven miles south of Mineral, the epicenter of Tuesday’s earthquake, at 12:19 a.m. Monday. Forty people reported feeling the 2.2-magnitude shudder as far out as Richmond, Va.

There have been no reports of significant damage as a result of these aftershocks.

Sigala said that aftershocks in the 2.0- to 3.0-magnitude range aren’t considered especially significant. She noted that after last Tuesday’s quake, people may be more sensitive to the earth’s rumblings.

“After feeling something so large as a 5.8, people may be more susceptible to feeling another smaller quake,” said Sigala.
