Theories have illuminated the Internet: The earthquake must have sparked a prolonged boom that shook homes Sunday morning in New Hampshire and at least one neighboring state.
Some have hypothesized that the sound of an airplane breaking through the sound barrier might have been a puzzling outrage. Both scenarios were quickly discounted.
Some meteorologists think they can explain this mystery.
Satellite images suggest a meteor may have exploded in the atmosphere over New Hampshire, according to those meteorologists who say the explanation is not far off.
They noted that this time of year is known for heavy meteor showers: the Draconids, which peaked two days earlier, and the Orionids, which last until November. According to the American Meteor Society, fireballs that explode in a bright, extreme flash, often with visible fragments, are known as fireballs.
“There was, of course, a small outbreak around the time people started calling and reporting sound,” said Greg Cornwell, a meteorologist for the National Weather Service in Gray, Maine, New Hampshire Forecast Bureau. interview on tuesday.
Cornwell said the flare was detected by a geostationary weather satellite known as GOES-16, which was used by the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration. He and his colleagues have watched the satellite channel since Sunday morning. On it, a blue dot flashed over southern New Hampshire around 11:21.
“It wasn’t until the next morning that we thought, ‘Well, I wonder what was the reason? “- he said. “There was a lot of discussion from the public.”
The satellite has an advanced lightning detection system, but there were no thunderstorms in the area on Sunday morning, Mr Cornwell said.
“There have now been cases where such exploding fireballs or fireballs caused false alarms,” he said. “It showed up in the data, and it’s kind of a guess.”
Doug Chappel, a mechanical engineer based in Hillsboro, New Hampshire, which is about 25 miles west of Concord, New Hampshire, said in an interview Tuesday that he was traveling with his family to Fox Forest when he heard the crash.
“I’m a Cold War kid,” Chappel said. “If I found out that Boston and New York were burned by a hydrogen bomb, I would not be surprised.”
Mr. Chappel said his family lived in Florida and were used to hearing the sound of a space shuttle launching and returning to Earth. What he experienced on Sunday — prolonged thunderclaps captured by a home security camera provided by Mr. Chappell — was something else.
“It took too long to be the signature of a sonic boom,” Chappel said.
Paul D. Raymond Jr., Strategic Communications Administrator for the New Hampshire Department of Security, said in an email Tuesday that the agency’s partners at Weather Services were observing the meteor as a source of concern and are investigating.
NASA did not immediately comment on Tuesday.
There have been no earthquakes in the entire northeast in the past seven days, according to the National Earthquake Information Center, which is part of the US Geological Survey and maintains a map of seismic events.
A spokeswoman for the Federal Aviation Administration said Tuesday that the agency had not reported any aircraft noise in the area, while local officials said the sound did not come from a military aircraft.
Mike Vancum, a meteorologist at WCVB television station, ABC’s Boston subsidiary, has come to the same conclusion as Weather Service forecasters that the meteor explosion may have caused the explosion.
“It now has to explode 30 miles or less to get that sonic boom,” Mr. Wankum said during Monday’s broadcast. “And it can take from one and a half to four minutes for this rumble to kind of pass. But this is probably what you heard. “
