Sonic Boom, Not Earthquake on Delmarva
There was no earthquake yesterday despite what residents felt in coastal Sussex County and nearby Ocean City, Maryland.
It was more likely a sonic boom caused by an aircraft.
The Lamont Doherty Earth Observatory and Cooperative Seismography Network examined seismographs with one in Lewes and did not find evidence of such a quake.
Joe Thomas, director of the Sussex County Emergency Operations Center, told the Wilmington News Journal that residents in Millville, Ocean View and Millsboro reported a shaking and rumbling.
There were similar calls from Ocean City but no shaking was felt in Georgetown.
