That shaking feeling was not an earthquake


That jolt you felt around 10:45 am Friday was not an earthquake, according to a geophysicist with the United States Geological Survey (USGS).

“Our best guess is there was some type of sonic boom,” Robert Sanders, a geophysicist with the USGS, told The Times. The agency has received more than 100 reports of “shaking” from Newport, Rhode Island, to Boston. “We show no seismic event in our data,” Sanders said. “That signals a sonic boom.”

All across social media individuals reported feeling a quick shake of houses followed by a smaller one. “I personally didn’t feel it,” said a woman calling from Martha’s Vineyard Bank in West Tisbury, “But people said they felt our building shake.”

This is a developing story.


  1. A bang as if a 100 ton trailer was dropped from 100 feet in the air followed by a rumble in the earth that passed from north to south, enough so that pictures rattled as it passed by the house. This was followed a few minutes later by a second occurrence. My impression at the time was that it originated quite close to my house southeast of the airport but obviously it was much more widespread.

  2. I remember when the Concord used to fly into New York. Every morning at at about 10:30 am there was a ‘boom – boom” . the 2 booms were less then a second apart. The classic signature sound of that phenomenon. I did not feel or hear this event.
    But, if it was a sonic boom, given the time frame of the second one being “a few minutes later” it would have been 2 separate aircraft, or one that had turned around..
