Mysterious Booms in SF Bay Area 3/5/2018: Giants Walking?

Tonight in the SF Bay Area at about 9:35- 9:45 pm there have been a ~10 minute series of low booms at such regular intervals as to rule out ordinary thunder. There are also no big storm clouds at this time.

No earthquakes.

That leaves explosions and fireworks. There are no fireworks planned that I could find, and this sounded bigger than most fireworks I’ve heard at a distance.

Checking out military exercises, I thought I’d found the answer: the US Marines firing high explosive mortar and tank munitions.

But where is this Camp Pendleton? Too far to be the answer:

That’s not it.

It just happens that I’m working on one of my 100 songs tonight called “the Mysterious Boom” which is about the following:

MYSTERY booming sounds have left people baffled all over the planet.

The terrifying noises have been recorded everywhere from the Middle East to the East Midlands this year – with the majority heard on America’s eastern coast.

The mysterious loud boom noise has been reported in multiple locations around the world this year

The latest boom came to light this week scaring residents in the US state of Alabama.

Cops say they were notified of a “suspicious sound” that was described as a “loud boom” at around 9pm on Monday.

The boom dubbed “Bama Boom” shook multiple houses and appeared to originate on the northwest side of Lochbuie, police said.

But cops and experts can’t seem to figure out what caused the mysterious noise.

Some experts say causes could range from supersonic aircrafts to meteors exploding in the atmosphere.

But apparently this isn’t the first time the mysterious sound has been heard with 64 locations reporting similar sounds this year.

Among those in locations include Michigan, Lapland, St Ives, Swansea and Yorkshire. Meanwhile, residents in Alabama took to Twitter to report the latest event. One local described it as “an incredibly loud boom” that “shook the entire house”.

@spann I heard and felt an incredibly loud boom from inside my home in Moody around 1:40-1:45pm today. Shook the entire house. Any news? Thanks!

This was heard across multiple counties this afternoon… doesn’t appear to be related to a geological event

Re: loud boom heard: we do not see anything indicating large fire/smoke on radar or satellite; nothing on USGS indicating an earthquake. We don’t have an answer, and can only hypothesize with you. 1) sonic boom from aircraft; 2) meteorite w/ current Leonid shower?

The Birmingham Alabamba National Weather Service said the noise could be from an aircraft sonic boom or a meteorite from the Leonid shower.

They tweeted: ‘Loud boom heard: we do not see anything indicating large fire/smoke on radar or satellite; nothing on USGS indicating an earthquake.’

Meanwhile NASA’s Bill Cooke told  ABC 3340 the origin of the mysterious boom still remains unclear.

He believes the sound could have been produced by a bolide, large supersonic aircraft or a ground explosion.

According to Cooke, NASA’s meteor scientists will continue to analyse new data in hopes of determining the cause of the boom.

What’s left, meteors? Giants walking around? A closer military base conducting parallel exercises? Let us know if you have the answer.
