Incidents of these mystery booms are becoming more frequent Residents in Alabama were left baffled last week when a loud boom resounded across much of the state. The boom, nicknamed 'Bama Boom', has left experts stumped, with suggested causes ranging from supersonic aircrafts to meteors exploding in the atmosphere. This isn't the first time that the mysterious sound has been heard, and incidents are becoming more frequent according to some reports. This year alone, similar noises have been reported 64 times this year, in locations including Michigan, Lapland, St Ives, Swansea and Yorkshire. Scroll down for a full list of booms in 2017 +5 Mysterious booms have been reported 64 times this year, in locations including Michigan, Lapland, St Ives, Swansea and Yorkshire. Incidents are becoming more frequent according to some reports. WHAT COULD THEY BE? In 2017 alone, 64 booms have been heard worldwide. The cause of most of the booms remains a mystery, although several explanations have been suggested. 1) Sonic booms A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound – such as supersonic aircrafts. Sonic booms generate significant amounts of sound energy, sounding like an explosion to the human ear. 2) Military exercises Many unexplained loud noises can be put down to military training, either at Army or Naval bases or in remote areas used for such exercises. 3) Controlled explosions A controlled explosion is a method for detonating or disabling a suspected explosive device, such as bags left at train stations. 4) Unusual weather Many loud noises link back to unusual weather events, such as electrical storms or thunder storms. 5) Meteors Large meteors passing above Earth often produce shock waves that can be heard as a sonic boom. 6) Sound amplified from aircraft Some have suggested that the sound was due to inversion - a phenomenon that occurs when a layer of warm air sits over a layer of cooler air, magnifying the sound of an aircraft miles away. 7) Aliens Some conspiracy theorists claim that the mysterious booms are noises created by aliens - although there is no evidence to support this. Alabama, November 14 Cause: Unknown, suggested explanations include a sonic boom from an aircraft or a meteorite The Birmingham National Weather Service tweeted: 'Loud boom heard: we do not see anything indicating large fire/smoke on radar or satellite; nothing on USGS indicating an earthquake.' The service suggested that the sound was either caused by a sonic boom from aircraft, or a meteorite from the Leonid shower. But Nasa has since cast doubt on these explanations. Speaking to ABC 3340, Bill Cooke, head of Nasa's Meteoroid Environment Office, said that the boom could have been caused by a supersonic aircraft, a ground explosion, or a bolide - a large meteor that explodes in the atmosphere unrelated to the Leonid shower. While the noise was picked up by the US Geological Survey, data suggests that the boom wasn't the result of an earthquake. The boom may have been caused by a military flight by a supersonic jet, although the US Air Force is yet to confirm this. The Bama Boom is just one of many mysterious booms heard worldwide this year. Idaho, November 15 Cause: Unknown The day after the boom in Alabama, a similar noise was heard in Idaho. Multiple people reported hearing a loud boom over the Lewiston-Clarkston Valley around 23:00. Many of the reports described the sound as being similar to a sonic boom, although its cause and location remain unclear. Cairns, October 10 Cause: Unknown, suggested explanations include a meteorite, a gas bottle explosion or military plane On October 10, a boom was heart over Cairns, Queensland that had the city baffled. Poster Comment: In the past these booms have been associated with coming earth changes and earthquakes. And that was before the invention of jet planes. Post Comment Private Reply Ignore Thread
