Something shook New Jersey on Saturday, but it wasn’t an earthquake

Posted on December 11, 2011


Local residents felt a slight tremor at about 10 a.m. Saturday. Residents in NewarkBergen County and Sussex County felt it, too — something that made houses shake and water ripple.

It wasn’t an earthquake.

But what was it?

U.S. Geological Survey geophysicist Paul Caruso isn’t sure.

“We received a number of reports that people felt something,” Caruso said from the National Earthquake Information Center in Colorado. “We don’t know what it was.”

“It could have possibly been a thunderstorm off the coast,” Caruso said. “A sonic boom, that’s another possibility.”

Caruso said this sort of thing happens several times a year, usually off the coast of Florida.
