The
quake is believed to have involved the Wabash fault, a northern
extension of the New Madrid fault about 6 miles north of Mt. Carmel,
Ill., said United States Geological Survey geophysicist Randy Baldwin.
The
last earthquake in the region to approach the severity of Friday's
temblor was a 5.0 magnitude quake that shook a nearby area in 2002,
Baldwin said.
"This is a fairly large quake for this region," he said. "They
might occur every few years."
Baldwin said the USGS revised the quake's magnitude from 5.4 to
5.2.
Irvetta McMurtry of Cincinnati said she felt the rattling for up
to 20 seconds.
"All
of a sudden, I was awakened by this rumbling shaking," said McMurtry,
43. "My bed is an older wood frame bed, so the bed started to creak and
shake, and it was almost like somebody was taking my mattress and
moving it back and forth."
Lucas Griswold, a dispatcher in West Salem, said the Edwards
County sheriff's department received reports of minor damage and no
injuries.
"Oh, yeah, I felt it. It was interesting," Griswold said. "A lot
of shaking."
Indiana State Police spokesman Sgt. Todd Ringle in Evansville said
there were no immediate reports of damage.
