Mystery boom heard in New Hampshire

A loud noise was heard in New England on Saturday, and some experts speculated it was a phenomenon called frostquakes.

Scores of local residents reported hearing the noise in southeastern New Hampshire and northeastern Massachusetts Saturday night.

Random booms are not entirely uncommon in New England.

The region has a seismic network that picks up even small earthquakes as they shake communities in the region.

However, no tremors were detected over the weekend, leading residents and weather experts to wonder about the cause of the recent boom.

meteorologist Matt Noyes Boston-affiliated NBC affiliate WBTS-TV reported that the cause of the explosive noise heard in Massachusetts and New Hampshire was likely a frost quake.

Although they feel similar, frostquakes are different from earthquakes.

The buildup for a frostquake happens when the ground is saturated from constant precipitation, such as snowmelt, and the air cools rapidly as colder air flows in, Noyes said.

The ground, which is normally already slightly above freezing, is rapidly cooling to below freezing.

As a result, the water in the upper centimeters of the soil quickly freezes.

Noyes compared natural occurrence to filling an ice cube tray.

If you fill the bowl completely, the ice will stick out and expand out of the bowl as it forms.

The expansion of water as it freezes in the ground causes the frost tremors as the ice settles in crevices or between rocks, eventually cracking the ground and projecting a booming sound.

Frostquakes rarely cause damage because they are shallow and don’t have the power of earthquakes.


In February, a couple in Kansas said they were witnessing the weather phenomenon of frostquakes, also known as cryoseisms.

NBC affiliate KSNT-TV spoke to Concordia resident Melody Gillan, who said she kept hearing pops that sounded like underground firecrackers going off.

Her husband, a longtime resident of Concordia who had never heard of Frostquake, thought someone was firing a gun in the distance.

“A few days later I was out and he finally decided I wasn’t crazy.” Gillan said KSNT.

“Something banged in the yard below ground.”

Texas residents have been issued with a warning due to the worrying weather Gorilla Hail the size of baseballs that could hit the state.

Experts said the biggest threat from the severe weather system will be large hail and damaging winds in excess of 60 miles per hour.

Gorilla hail can damage car windows and roofs.

“Strong directional wind shear, cold puddle of air in the air and expected storm mode from supercells favor large hail of two inches and larger in diameter,” meteorologist Reed Timmer told The Sun.

“Even a short tornado is possible.”
