Reports of a shaking feeling across parts of South Jersey are spreading through the Internet. And the U.S. Geological Society which tracks earthquakes and other such activity has posted an intensity map of the incident they think might have been a sonic boom.
Reports are showing that people from as far east as Mullica Hill and from Barnegat Bay to Cape May felt some weak to light shaking. Egg Harbor Township has so far reported the most activity.
According to the USGS, sonic “booms” tend to occur more in the Northeastern US and along the East Coast.
“No one knows for sure, but scientists speculate that these “booms” are probably small shallow earthquakes that are too small to be recorded, but large enough to be felt by people nearby.”
