Ocean City, Maryland is abuzz with speculation after a series of tremors that resembled an earthquake shook the town and neighboring communities.

One resident reported the boom that accompanied the strange quaking was so loud that it “sounded like somebody blew something up.”  Bart Rader told the Baltimore Sun a 50-pound metal sculpture on his wall began shaking.

Geologists claim the tremors were not the result of an earthquake and speculated that supersonic jets from the Paxuxent Naval Air Station caused sonic booms.  However, no station officials could confirm flights massing Ocean City.

“We’ve had sonic booms in town before, but this seemed different,” firefighter Michael Maykrantz said. “It was more sustained, and then there was a pause for about a minute and then it started again.”

Seismologists also said the tremor was not a result of a frost quake which has been happening during this frigid winter.
