SOUTH VINELAND, N.J. (1010 WINS) -- Supersonic flight testing in the Atlantic Ocean likely caused mysterious rumblings in parts of New Jersey this week, the Navy said Friday.

The vibrations were reportedly felt in Cape May, Cumberland, Ocean counties on Monday afternoon. Nearly 50 reports about the incident were submitted to VolcanoDiscovery.com.

“Whole house shook and vibrated for a few seconds,” one person wrote from Cape May. “A rumble in the distance and our building vibrated in an unusual way,” a person in Rio Grande said.

During that time, Naval Air Station Patuxent River in Maryland had an aircraft “executing supersonic test points as part of an approved test plan in a supersonic approved area,” a Navy spokesperson told NJ.com.

According to the spokesperson, the Navy uses a strip of airspace known as the offshore “Test Track” for military testing that can sometimes require supersonic speeds.

The tests start three miles offshore over the Atlantic Ocean to avoid populated areas. While sonic booms aren’t usually noticed on land, it can happen due to weather conditions and “details of the test flight,” the spokesperson said.

No seismic activity was detected by the U.S. Geological Survey.
