First quakes, then sinkhole: Oklahomans wonder about a connection

A large sinkhole has opened up near Sayre, Okla., and people in the region are wondering if it's related to a string of small earthquakes shaking the region.

The hole opened up a couple of days after one of the earthquakes about two weeks ago, the property caretaker told NBC station KFOR.

"Kind of spooky. You don't want to mess with it today," Jack Damron told KFOR.

"Glad my house wasn't over it," neighbor Tony Bills told the station. 

KFOR reported that geologists are dubious of a connection between the quakes and the sinkhole. Scientists at the Oklahoma Geological Survey said the sinkhole could have been caused by drought conditions, the dissolving of salt or rock formations, or draining of an old coal mine.

Also, Sayre is across the state from the area where the quakes have been centered. That area, about 40 miles northeast of Oklahoma City, was struck on Nov. 5 by a magnitude 5.6 quake, the strongest ever recorded in the state. There had been a 4.7 quake earlier in the day. The big quake caused minor damage to buildings and roads in the area.

And the shaking has continued since then. There have been a string of small quakes over the past week; the strongest was a 3.7 on Thanksgiving. There was a 2.7 on Tuesday morning.
