At least 5 aftershocks after large Eastern US Earthquake
RICHMOND, Va. (AP) – The 5.8-magnitude earthquake Tuesday that
shook people from Georgia to Canada has produced at least five
aftershocks.
The U.S. Geological Survey says the aftershocks around the central
Virginia epicenter had ranged in magnitude from 4.2 to as little
as 2.2 since the strongest earthquake to strike the East Coast
since World War II. Another hit early Thursday with a magnitude
4.5 and 3.1 miles deep.
Amy Vaughan, a geophysicist with the National Earthquake
Information Center in Colorado, says the number of aftershocks so
far has been remarkably low.
Vaughan says the agency isn't sure what to expect, but it's likely
there will be some more for days, if not weeks. Typically, the
larger the quake, the longer and the greater extent of
aftershocks.
