Loud booms being heard worldwide

These videos show a number of incidents featured on the news or reported on social media, where there is a very loud boom powerful enough to shake homes, or trumpet-like sounds. In many cases, local authorities said they were unable to find a cause.

In the first video below, the noise around 4:28 is basically identical to what I heard and talked about in my "What do UFOs sound like?" thread. I made that thread March 11th, and I'm noticing many of these incidents also take place in March of this year.

"After receiving several phone calls from concerned viewers regarding loud, explosive noises and ground shaking, NewsChannel 10 investigated the cause of the disturbance.

The National Weather Service has confirmed 4, F-16 jets created a sonic boom as they flew over the northern part of Amarillo."

In other cases, it's strange that local authorities were unable to verify the cause.

It's strange to me that planes can make so much noise, loud enough to make houses shake and things fall off the walls, without the military/government having to explain.

El Dorado, CA, not sonic booms but military operations 100 miles away:

"Mysterious booms have plagued the residents of El Dorado County in California for some time now. While some have speculated what the cause of these booms has been, it's remained a mystery until now.

Residents have reported that the booms aren't as crisp as a gunshot, and instead sound more like an aerial bomb. A few have speculated that it could be the result of work occurring in an underground mine.

It seems, though, that these aren't the case. The mystery booms are actually the result of the Hawthorne Army Depot destroying obsolete munitions on weekdays. This base is located 100 miles away in the Nevada desert.

"I can't explain all the physics involved, but the atmosphere is bouncing in response to the energy and it's reflecting and bouncing (the sound) back down," said Glen White, a science instructor at Columbia College outside Sonora, in an interview with Phys.org. "The really odd part is people fairly close to the source of the energy, the explosions, aren't hearing it. The sound goes over them."

White and the SMU team actually wanted to calibrate four sensor stations, using the known source of daily explosions at Hawthorne. That's when they found that the blasts heard by California residents came from Hawthorne. Sound actually carries fairly well in the summer months, which explains why so many residents have been hearing the explosions."

"Skyquakes or mystery booms are unexplained reports of a phenomenon that sounds like a cannon or a sonic boom coming from the sky. They have been heard in several locations around the world such as the banks of the river Ganges in India, the East Coast and inland Finger Lakes of the United States, as well as areas of the North Sea, Japan, Italy and in Drogheda, Ireland.

They have been reported from: on an Adriatic island in 1824; Western Australia, South Australia & Victoria in Australia; Belgium; frequently on calm summer days in the Bay of Fundy, Canada; Lough Neagh in Northern Ireland; Scotland; Passamaquoddy Bay, New Brunswick & Cedar Keys, Florida & Franklinville, New York in 1896 & in northern Georgia in the United States.[4]

Their sound has been described as being like distant but inordinately loud thunder while no clouds are in the sky large enough to generate lightning. Those familiar with the sound of cannon fire say the sound is nearly identical. The booms occasionally cause shock waves that rattle plates. Early white settlers in North America were told by the native Haudenosaunee Iroquois that the booms were the sound of the Great Spirit continuing his work of shaping the earth."

I didn't get a chance to properly view the videos until today. Where do you find this cool stuff Ava?

I wonder what it is. It's great that technology allows us to film and record such phenomenas. Just imagine when it happened in 1824, how would you make yourself believable when describing what you've heard. I'd love to experience it myself too.
