Loud boom that rocked Newark not an earthquake, remains a mystery
A loud boom rocks Newark.
WDEL's Amy Cherry reports.
The startling boom was felt at Marrows Road near Route 273 in Newark at 1:20 p.m. Thursday.
Dave Munion was sitting at his desk at work.
"It was a heavy, solid thud, and I thought somebody dropped something on our roof," says Munion.
He tells WDEL the whole building shook and everyone was left wondering, "what was that?"
"We went outside, and everybody was outside looking around. companies across from us, they were outside, and they were looking for something. They didn't know what it was," says Munion.
They were thinking, maybe, it was an earthquake.
But David Wunsch state geologist and director of the Delaware Geological Survey says "no."
"We also looked on our seismographs and did not see any signals typical of a small earthquake," says Wunsch.
He says the U.S. Geological Survey didn't record any seismic activity in our area.
Wunsch says Wallops Island didn't have rocket testing scheduled for Thursday either.
"Sometimes it can be a military exercise or planes flying off the coast at supersonic speeds," he explains.
He says the boom could have been construction.
"They drop a large beam on the ground, it can radiate quite a distance and cause a boom like that," he says.
State Police and Newark's Aetna Hose Hook and Ladder Company know nothing about it.
So for now...
"It is a bit of a mystery, and we may never know," he says.
Social media reports a similar disturbance in both Philadelphia and Baltimore.
