Oklahoma officials survey damage after strongest quake in state history
"This last one shook much harder than the one this morning," Greff said, referring to a 4.7 magnitude quake in the early morning hours Saturday.
As he fielded a call from the county emergency operations director, he said he had not received reports of serious injuries from the latest quake, which struck at 10:53 p.m., Central Time.
The latest and strongest quake sent shockwaves for about 20-30 seconds, authorities said.
Survey officials said the earthquake was at a depth of 3.1 kilometers and most likely occurred on the Wilzetta fault, also known as the Seminole uplift.
After the 5.6 quake, Greff said he began surveying city buildings for damages. A piece of ceiling had fallen in one of the local libraries, but there were no other major damages, although he said, "it's still a little early to tell what we've got."
At his own home, a few dishes fell and pictures were tilted on the walls, he said.
"We're not really expecting earthquakes--that's for California, not Oklahoma," he said.
He said he planned to continue investigating the quake's impact overnight.
Lincoln County sheriff's dispatchers for the surrounding area said no serious injuries had been reported after the latest quake.
