A 4.8 magnitude earthquake centered in New Jersey caused minor tremors on Martha’s Vineyard Friday morning, according to the U.S. Geological Survey’s Earthquake Hazards program. 

The earthquake occurred at 10:23 a.m., with the epicenter in Whitehouse Station, New Jersey, an area in the northern part of the Garden State. The earthquake rocked the tri-state area, but at least 15 people on the western side of the Vineyard reported feeling the effects of the quake to the USGS.

Rob Hammett, an East Chop resident, felt the shockwaves Friday morning. 

“I was sitting up on the third floor of my house in my office. And the house started wobbling a little bit for about five seconds,” he said. “A few seconds later, it started again and wobbled again.”

The Island’s reports to USGS were all categorized as a weak level of shaking, one of the lowest ratings. 

The earthquake was felt as far south as Washington, D.C. and as far north as Maine, according to the USGS. There were no immediate reports of injuries or damage. 

Earthquakes are seldom felt on Martha’s Vineyard, though a 3.6 magnitude in Dartmouth was felt across the Island in 2020. 

More than 150,000 individuals reported feeling impacts of the quake in the northeast, according to USGS.
