Supersonic boom, sky motorcycle, weather anomalies, among other explanations, have been proposed to explain a strange sound that has manifested itself this week in San Diego County, without anyone knowing for sure where it came from or what caused the mysterious boom. Has the Hum come back?
It shook windows and doors in a large swath of San Diego and Tijuana late Wednesday afternoon (March 10), shaking the nerves of residents who had experienced a similar noise last month, which they dubbed “Boom.” .
The first thought of many people – being California – was “earthquake!” But the United States Geological Survey denied such a thing. Its seismic activity sensors registered absolutely nothing.
And being San Diego a longtime military aircraft base, many people also thought of the “sonic boom.” However, when the Cmdt. Zachary Harrell, a spokesman for the Navy, noted that it is a requirement for planes that break the sound barrier to do so far from shore. “That was not one of us,” he declared.
The marines? They have not yet responded to a request for comment from the press. Could some local defense contractors be testing some kind of novel weapon?
In 2012, when a similar boom shook windows and doors along the local coastline, initial denials of “it wasn’t us” by the military gave way to a later admission: the pilots of two F / A planes. 18 of the Navy had been showing off to guests aboard the Carl Vinson aircraft carrier during a family cruise.
“Those two planes went supersonic about 35 miles offshore,” a Navy spokesman said at the time. “You don’t usually hear lateral sonic booms travel that far. It was a bit surprising for us.
On the occasion of a few days ago, Humberto Mendoza Garcilazo, from the Center for Scientific Research and Higher Education in Ensenada, said that supersonic planes may have been responsible for the “roar.” But he also suggested that it could stem from the day’s stormy weather and drastic changes in temperature and atmospheric pressure.
However, Brandt Maxwell, a meteorologist with the National Weather Service in San Diego, was skeptical about the links to the weather. He said there were no thunderstorms in the area at the time of the boom, which was around 5pm, and “even with a strong cold front, you won’t get that kind of rumble.”
So, for now, what caused the mysterious boom remains a mystery.
While the sound reported in San Diego seems to have more fleeting characteristics, many have also linked the phenomenon to the famous Hum, a strange sound that seems to come from the sky and that has manifested itself in various parts of the world over the last few years. years.
The last time we heard about the subject was in 2020, in full confinement due to the coronavirus pandemic, when the Argentine skies vibrated to the rhythm of the Hum for several nights.
