Mystery Booms From The Sky (Skyquakes)

Definitely meant tio shoot down dodgy aircraft. An accident will happen yet.

EL DORADO COUNTY (CBS13) – People from all over El Dorado County say they’re hearing loud booms several times a week, but there are many theories on what is causing them.

“I thought it was thunder,” said one person.

“It’s definitely not thunder; too consistent. I thought it was just mining,” said another person.

“I always considered them to be sonic booms from flying aircrafts for years,” said Loring Brunius, owner of Sierra Rock Diamond Quarry.

People who live near Pleasant Valley say their days have been interrupted by loud booms, shaking the floor beneath them.

“You can feel it in the ground, no question about it. But no one’s been able to figure out why,” said Pleasant Valley resident Peter O’Grady. “I tend to hear somewhere between four to six of these things during the weekdays usually between 11 p.m. and 2 p.m.

“Boom, boom, boom, boom just like that,” said Lorren Gonzales, who lives near Pleasant Valley.

And the rolling foothills of El Dorado County make it difficult for them to even tell where it’s coming from.

We asked the owner of Sierra Rock Diamond Quarry what he knew about it. He says they havent blasted since last year. And any miners or quarry owners would need government permission before they can set off any explosives.

“It’s a federally mandated system, and enforced,” said Brunius.

Some think the booms are from nearby wineries using propane cannons to scare away birds.

“We’ve never done it and I don’t know of any other winery that does,” said Carrie Bendick, a winemaker at Holly’s Hill Winery.

According to USGS, there aren’t enough seismic stations to pinpoint the exact location. Meanwhile, some say the booms have been around so long and happen so often they barely notice them anymore. Still, others want to solve the mystery.

“I would like to know what it is, yeah. And I’d like to know when it’s going to stop too,” said O’Grady.

CBS13 spoke to Fallon Naval Air Station that said any supersonic flight operations they do are only allowed over Dixie Valley, which is hundreds of miles away.

Some think illegal mining could be the source of the sounds, but Brunius doubts that theory. He said if that was the case, the culprit would have been caught by now.
 
'Meteor' prompts Devon and Cornwall tremor reports

People across Devon and Cornwall have inundated police with calls saying they had experienced an earth tremor.
Officers from the region said they received reports of people hearing loud bangs and buildings shaking from about 16:00 BST on Thursday.
Police staff in Devon's Newton Abbot station also said doors blew open.

The British Geological Survey said it had no evidence of a tremor, but added it could have been a sonic boom from a meteor falling to earth.

Sonic boom heard in Essex, Cambridgeshire and Hertfordshire

"Loud explosions" heard across the east of England were caused by a sonic boom when a jet broke the sound barrier.
The noise, at 11:30 BST, caused shaking and smashed windows and prompted calls to police in Cambridgeshire, Essex and Hertfordshire.

The Ministry of Defence said a Typhoon jet from RAF Coningsby in Lincolnshire was launched when communication was lost with a Heathrow-bound plane.
It is understood the plane, travelling from the USA, landed without incident.
Air traffic controllers had become concerned but communication was re-established with the passenger airliner and there were no problems on board.

Speaking of Sunday's sonic boom, Insp Matt Snow of Cambridgeshire Police said: "We've had reports of windows being smashed.

"One man who rang us from St Ives thought something had hit his roof because the whole house shook.
"It was so loud another person thought his neighbour's house had blown up.
"People have said they'd never heard anything so loud in their lives.
"Even people driving on the A14 have been calling us."

Elaine Mason, of Great Gransden, Cambridgeshire, told the BBC: "I had just got on my horse and was walking around the arena, when I heard a thunderous bang.
"I couldn't believe it was thunder, it was about 10 times louder than that.
"I thought it might have been an explosion. She [the horse] reacted immediately."
Her husband, Tim, who was gardening nearby, said he thought the "almighty bang" could have been a crash.

Jets from RAF Coningsby were scrambled last month to escort a passenger plane over the UK.
The airliner from Pakistan, heading to Manchester, was diverted to Stansted and two men on board arrested by Essex Police.
The BBC understands the incident was not terror-related.

Why did my ancestors move to a place with "frost quakes"?


Mysterious Christmas Eve ‘boom’ heard and felt around GTA

By Nicole Mortillaro Global News


TORONTO – Did you hear it?

Around 11 p.m. Christmas Eve, people reported hearing a loud “boom” in Toronto, Newmarket, Aurora, Belleville, Richmond Hill, and Sutton. Not only was the boom heard, but it rattled houses, leaving many to believe that a tree had fallen on their rooftop.

<edit peoples tweets>

But so far, there hasn’t been an official explanation.

Even more mysterious is that some people reported hearing booms at other times during the day as well, ranging from 2 p.m. to 6 p.m. to 1 a.m. on Christmas morning.

The United States Geological Service (USGS) didn’t record any seismic event in Ontario yesterday, and there were no reports to the American Meteor Society.

So what was it?

The most likely explanation is that it was a cryoseism, also known as a frost quake.

Cyroseisms are rare, localized seismic events that occur when a sudden drop in temperature freezes the groundwater, which then expands and cracks the soil and rock. The crack will release a sudden burst of explosive energy, resulting in a loud noise and the shaking of the ground. They usually occur between midnight and dawn.

Temperatures north of the city — in Newmarket, Richmond Hill, and Sutton, for example — were a chilly -20 C or colder on Christmas Eve.

On January 18, 2000, when temperatures were near -20 C in Sadowa, Ontario, 12 frost quakes were recorded in two hours.

Cryoseisms are rare, but they seem to be more common around the Great Lakes.

Two similar events took place in the U.S. in 2011 and 2007.

According to media reports, in 2011, residents in southwestern Ohio and Indiana reported being awakened by a loud boom as well as the shaking of their homes.

A similar incident occurred in 2007 in Ohio.

What is similar about these events and the Christmas Eve events is that all of them had recently experienced an ice storm.

Is this the answer to the boom of Christmas Eve? We won’t know for sure, but it does seem to be the most likely explanation.

Then again, it could just have been a very noisy Santa.

This has turned up in World Wide Words newsletter today:

Quaking cold

The extreme cold in Canada earlier this week led to the appearance of the term frost quake. In Toronto, for example, there were reports of hundreds of people being startled by loud booms that resembled gun shots. The cause was water deep in the ground becoming frozen and expanding, causing explosive cracking of the soil. The scientific term for it is cryoseism, described in a work of 1980 as “a non-tectonic earthquake caused by freezing action in ice, ice-soil and ice-rock materials”. Though rare outside the polar regions, they’re known in Canada and the northern states of the US and the term frost quake is much older than some reports have suggested. In January 1918, for example, two newspapers in the Boston area reported, in small news items on an inside page, that people were woken and houses shaken as the result of a frost quake, so named. The Boston Globe noted in a subheading “Frost quakes not uncommon in Maine, but rare in Bay State.”
 
Hundreds report mystery 'explosion' in Manchester

A mysterious explosion heard across parts of Manchester and Salford remains unexplained.
Hundreds of people took to social media to describe hearing a "loud bang" at about 22:30 GMT on Monday.

Firefighters were called after a report in the Weaste area of Salford but later admitted they could find no evidence of a fire, or any other disturbance.

Shinydan Howell posted on Twitter: "Everyone in Manchester ok? Loud bang in Salford could be anything."
Lana Habbal posted: "Everyone is talking about a loud bang in Manchester I hope nobody is hurt."
Francis Jenkins, another Twitter user, said there had been disturbances to television and mobile phone networks.

A spokesman for Greater Manchester Police said they had found no evidence of any disturbance.

Terrorists testing a bomb?

If so, let's hope the bastards blew themselves up! :twisted:

Remember in Four Lions, the incompetent jihadi who tripped over a sheep and blew himself up?

That was what I had in mind, yes.
 
There was a mystery explosion in the Campsie Fells above Glasgow a couple of years ago, which resulted in an anti-terrorist police operation, but turned out to 'just' be an illicit still.
 
Following on from the Manchester Boom on the 25th it seems there was a mystery "explosion sound" in the early hours of today (29th November) in the Catterick North yorks area.

A1 has been closed by the police all day

BBC news reports it here

Oddly a friend who is up there today, says there are police everywhere, but so far no trace of an actual explosion can be found and a lot of head scratching is going on.

Mr P
 
This Catterick story has me scratching my head. Perhaps 2 or 3 years ago. someone posted on the MB a Fortean story of some kind (ghosts?), but it was obvious they wanted to keep their location private. But googling on some stuff they did post, it was easy to work out the location, so I PM'd the poster and the post was changed.

Now I don't recall the story or the poster's name (the PMs I've kept don't go back very far) but I do remember the location was Catterick Barracks! I can't search for the story because Catterick wasn't actually mentioned, even in the original version of the post.

If that poster is still on FTMB, and has any inside gen on this mystery explosion, it would be good to hear from them!

I've now located a post I made almost exactly 3 years ago on Personal Data on the Internet:
I've just had an exchange of PMs with a poster who wanted to keep a certain location private, but had included a quote about it (with the name blanked out).

I had to point out that the amazing search power of Google allowed me to find the origin of the quote (on a well-known website) within seconds!

So it's better to paraphrase such stuff, and give no hint of the source either. (This has now been done by the poster in question.)

There was another example a few years ago, where a case was under discussion, and one poster quoted a local newspaper report, but with certain names omitted. Google soon found that one too!

(Yes, I am a nosey bugger! )

http://www.forteantimes.com/forum/viewt ... 28#1160728
So, perhaps there's a ghost or polt at Catterick which specializes in outdoor explosive noises... ;)
 
Perhaps it was just a horse backfiring?

:)
 
OK, since last posting here, people are claiming to have heard more of these explosions / bangs last night in other locations?


Mystery as 'explosions' and 'loud bangs' are heard across UK from London to Glasgow


Nov 29, 2014 23:29
By David Raven

Some suggested it sounded like 'fireworks' - but others compared the loud noises to 'aircraft sonic booms'

Loud bangs: Dozens of people claim to have heard the bangs across the UK

Several loud 'mystery bangs' that shook windows baffled people across the country on Saturday night.

Dozens of Twitter uses from London to Glasgow claimed to have heard the strange noises, which sounded like fireworks or loud aircraft and occurred between 10pm and 10.30pm. Some suggested it sounded like 'aircraft sonic booms' and pointed to Russian airships that were performing 'routine military exercises' while passing through the English Channel.

But the Ministry of Defence denied any knowledge of jets being scrambled and Met Police said the only possible explanation they were aware of was a firework display in Croydon.

However others were reporting to have heard bangs around the same time over 100 miles away.

Sonic boom: Several Twitter users claim the noise could have been made by aircraft and several claimed on social media that their pets appeared to have been 'spooked' by the strange noises.

Twitter user Dave Reed claimed: "Dogs went crazy for a couple of minutes here in Fareham. Assumed audible distant bangs were fireworks."

But a Met Police spokesperson said apart from the firework display, they were unaware of any ongoing incidents the bangs could be related to.

Britain has been on its second highest terrorism threat level of severe, meaning an attack is considered highly likely, since August.

At 3am on Saturday morning a loud explosion was reported to have been heard in the area near to Britain's largest army training base Catterick. Police were unable to find evidence of an explosion. Police carried out a lengthy investigation involving counter-terrorism experts, a helicopter and bomb detection dogs.

But despite closing the A1 motorway and a the search taking up the whole of the day, no official explanation was given and no evidence of any explosions were found. Earlier this week another mysterious bang was heard over Manchester by several residents - fire crews spent an hour searching for the source of this but nothing was found.

Speaking about this morning's 'explosion' in Catterick, police superintendent Dave Hannan said: "We are satisfied that the call to the police was made in good faith.

"In view of the location of the suspected explosion, the source of the information, the current threat level to UK security and a report a few hours earlier of a vehicle seen in suspicious circumstances outside the barracks, we were not prepared to take any chances with people's safety."

On Monday, Home Secretary Theresa May said Britain was facing the biggest terrorism threat in its history.

Since August dozens of terrorism suspects, including some accused of plotting to kill police officers or soldiers, have been arrested.

Source Mirror online

A few people I follow on Twitter have mentioned hearing a loud explosion around 10pm last night. Only one of them is in Norfolk and the other is in Scotland. Furthermore, the MET police helicopter crew tweeted about one, but then deleted the tweet shortly after?

Suspicious?

Atmospherics, I expect. I've heard 'explosions' before that turned out (probably) to be heated air rising through cold air - there was very warm air for the time of year next to the ground yesterday and it was cold overnight.

Any meteorologists out there who can confirm this rather odd mechanism for an atmospheric 'explosion'? I've never heard of such a thing nor can imagine how a very loud noise can be generated in the atmosphere without and 'explosion' caused by either a sonic boom, lightning or a bomb!

This is my sort of mystery.

Multiple witnesses, emergency servies closing down roads, the military reporting explosions to the police, windows rattling and hundereds of miles between the reports.

Meanwhile, in the English channel, Russian warships "waiting out a storm"...

I live in a fantasy film world. :lol:

First I've heard of this.

Is there something we're not being told? Like, a foreign power has fired a few airbursts over British airspace just to gain our attention? Or something like that.
 
Theres a thread for this going back to 2001 so you should find some interesting stories there. Topics merged.
 
I went out for a walk this morning and could hear bird scarers booming away, could it have been some farmers using them during the night maybe?

I was wondering what kind of routines airships had got back into! :?
