At various places around the domain people have describe strange , loud get it on noises that seem to be coming from the sky . Around the world they are know as “ Barisal guns ” in the Ganges delta and the Bay of Bengal , “ yan ” in Shikoku , Japan , and “ mistpouffers ” ( fog belches ) in Belgium .
Forhundreds of yearsthere have been reports of unidentifiedboom noisesacross the US . Sometimes company by earthquake , sometimes not , they have been heard during the New Madrid temblor of 1811 - 1812 right up until January of 2020 . They’reoften describedas a " rushing " or " rolling " speech sound , and occasionally are consociate with cold temperature rather than earthquakes .
tacky banging noises have been have intercourse to happen particularly often near Lake Seneca in the Finger Lakes region of New York . Known as the Seneca Guns , the sounds are so loud they occasionally canrattle windows and doors , and go back to the Charleston seism in August 1886 when the disturbance were discover for several week after the event , coinciding with the many aftershock .
In 2020 , scientist used seismic data from the EarthScope Transportable Array ( ESTA ) to attempt to explain the noises around the US , comparing it to chronicle of the noise from 2013 onwards .
The squad from University of North Carolina at Chapel Hill trawled back through newsworthiness report from North Carolina , where reports of the noise have come middling oftentimes . The team hoped to be capable to verify the racket with seismo - acoustic data take from ESTA . They did n’t find any result that coincided with earthquakes , cater grounds that they are unlikely the causa .
" Generally speaking , we believe this is an atmospheric phenomenon – we do n’t cogitate it ’s coming from seismic activity , " researcher Eli Bird said in a program line attend byLive Science . " We ’re assuming it ’s propagating through the ambiance rather than the ground . "
The research worker , who presented their finding at the annual confluence of the American Geophysical Union in 2020 , focused instead on heed to infrasound datum – low - frequency sound that is n’t hearable to humans . They did peck up signaling – varying between 1 and 10 second farseeing , Live Science reports – associated with report boom
However , we ’re not a lot closer to an explanation for the noises , nor whether the noises are make by the same type of event around the Earth . Many could be transonic booms from aircraft breaking the sound roadblock , rather than unknown natural suit . Possible explanations for other event grade from storm wave and tsunami being amplified in a particular centering and lighting ofmethanegas give up from methane hydrate beds , togeomagnetic tempest .
One promising possibility is bolides in the upper standard atmosphere – meteoroids producing asonic boom , where the shooting star go unseen and is n’t noticed until we listen the noise it creates . For now , until more datum is gathered , the noises remain unsolved .
