What was that? Many Valley residents reported shaking and loud booms on Thursday night.

Dear AZ, was that an earthquake? @abc15

The United States Geological Survey has not reported any earthquakes in Arizona in the past 24 hours. So the question must be raised...what was it and how did so many people around the Valley feel it?

The Arizona Geological Survey said they could not identify any large earthquakes in the area. It is possible there was a very small earthquake that occurred and it was not detectable.

Scottsdale resident Maria Rodriguez said she felt the shaking from her home. "We felt the doors shake, like somebody was trying to push them in, but we didn't see the doors move," Rodriguez said.

Luke Air Force Base said they do not have any information about sonic booms in the area. Air Force captain Becky Heyse said there was an aircraft flying around 8:30 p.m. Thursday, but it was "unlikely" the jet caused a sonic boom in the northeast Valley because they were flying 60 miles west of Glendale.

Research geologist Jeri Young said there weren't any signs of a earthquake in the Valley. "There were some signatures of maybe a man-made disturbance," Young said. "We can't really say where it occurred or what it was based on our equipment."

People across the Valley reported a loud booming noise and mysterious shaking of their windows and doors last night.

Some took to Twitter, believing it was an earthquake. But the US Geological Survey reports no earthquakes of any magnitude for at least the last seven days.

Aviation experts said a high-altitude sonic boom could sound like a low rumble. Civilian aircraft are prohibited from flying at supersonic speeds over the continental U.S., but military aircraft are allowed to break the sound barrier.

However, most of the reports of loud booms were centered in the north Valley. According to airspace charts, commercial planes come into Phoenix from that direction, but some military training routes cross them at varying altitudes.

So far, no agency has admitted to flying at supersonic speeds over Arizona. A last possibility could be a meteor exploding at high altitudes.

Natchitoches officials are searching for an explanation for a loud boom that nearly four dozen residents say shook their homes.

The parish's 911 call center received about 50 calls reporting the loud boom just before noon Saturday, the Natchitoches Parish Sheriff's Office reports. Most callers said that they felt their houses shake and that windows, pictures on the wall and dishes shook as well, Sheriff Victor Jones said.

Deputies who went to areas of the parish where the boom was heard were unable to pinpoint an exact location.

"Over the course of the last week, U.S. Forest Service has been conducting numerous control burns in south Natchitoches Parish consisting of several thousand acres which have caused smoke haze in the area," sheriff's Capt. Tony Moran said. That wouldn't explain the noise.

And Fort Polk officials said no military training operations were being held at Peason Ridge.

Loud boom was heard across Doha at around 8: 35am in morning, many people started posting on social media and discussing the same.

One of the user in an online group on Facebook, Sanesh Chembakath, posted that he felt like an earthquake. One more facebook user, Dana Barakat said, he heard a loud bang in Al Waab area.
Many suspect to be a case of sonic boom. More details are emerging.

Residents across the north Dayton, Englewood, Clayton and Trotwood areas reported a loud boom this evening that shook their houses.

"We just heard a huge explosion, like a sonic boom," said one caller in the 8300 block of East Westbrook Road, near Seybold Road. "It happened very close by. It jarred the house. It sounds like a house explosion."

The Montgomery County Regional Dispatch Center and Englewood police said they received reports around 6:25 p.m. about the loud boom.

Many residents took to social media, questioning the source of the boom on Facebook pages.

Englewood officers and Montgomery County sheriff's deputies responded to the area but were not able to find anything that may have caused the boom.

A loud explosion heard Saturday in some parts of Orangeburg County remained a mystery Monday.

The explosion was reportedly heard in the Eutawville, Cope, Cordova and Norway areas, causing the ground to shake.

"It was significant," Orangeburg County Chief Fire Operations Officer Teddy Wolfe said, noting he heard it from his residence in Eutawville. "I would like to know what it was."

The Orangeburg County Fire District, however, did not receive any reports of a fire or explosion.

The South Carolina Department of Natural Resources State Geologist Charles William "Bill" Clendenin Jr. said there were no reports of earthquake activity that came across his desk for Saturday.

The South Carolina Emergency Management Division and the Orangeburg County Emergency Services Department said they did not receive any reports either.

Some say it shook homes, knocked items off their walls.

Numerous people living on the west side of Hamilton reported hearing a loud boom around 5:40 p.m. Sunday. Some say it even shook their homes and knocked items off their walls.

"No other way to explain it other than a loud boom," Darryl Pies said. "It was different than firecrackers or perhaps a transformer blowing up. I mean,it was 'boom,' and a little bit of a rumble after that."

Earl Caudill said he felt it. "I felt the concussion. You could feel the concussion from it," he said. "Of course, you come out to see if you could see smoke and stuff. There was no smoke out here."

Multiple people called 911 after hearing the noise. "It shook my mom's apartment. I mean, it was huge, and now all kinds of people are saying they felt it, so it was something," one caller said. Another caller said, "It was so bad that it blew a clock off my wall."

The booms are loud and deep, enough to rattle the dishes.

"I have heard it four times Saturday night through Sunday night," says Carolyn Risko, who lives south of Lancaster. "It's very loud and shakes the house."

She and other residents of the area have been trying to determine the cause of the loud noises, but they haven't had any luck.

Risko says she went outside after each boom but "didn't see anything."

Residents contacted Manor Township police and spoke to an officer who also heard the booms, Risko says. Firefighters, too, patroled the area searching for the cause.

"They can't pinpoint a location so they can't really investigate it," Risko says.

Manor Township police Sgt. Gary Gardner says he doesn't think anyone has tracked down the source of the booms.

Whitley County law enforcement and volunteer firemen have investigated calls from homeowners in southern Whitley County of at least two loud "explosion" noises that rattled homes and homeowners alike.

The calls came into emergency dispatch centers between 6:30 and 6:45 p.m. Saturday. Both Whitley County and Huntington County dispatch centers fielded calls, including one from the Roanoke town marshal.

Whitley County responders investigated the areas between Meridian and Washington Roads near CR 800 South after the Saturday night phone calls but were unable to find the sources of the loud booms.

Homeowners reported the explosive noise literally shook their houses.

Possible sonic booms from air craft in the area were discounted as the cause as there were no Air National Guard exercises ongoing at the time.

Another cause could be the phenomena named "frost quakes," although those usually happen in much colder weather; however, there is also a moisture component to the freak winter events.

From as far back as 2008, video recordings of strange and eerie sounds have been appearing on the internet. They occasionally garner a mention in the media but are generally ignored or explained away as a 'hoax', the result of "secret government weapons", the "activation of HAARP" or "HAARP-like technologies", the by-product of "top secret construction work on underground bases", or "aliens", etc., etc.

Variously described as groaning, metallic, clashing, clanging and trumpet-like, these (usually loud and pronounced) noises seem to come from the sky but generally reverberate in such a way that listeners are unable to make out from which general direction they come.

These 'strange sky sounds' have been observed all over the globe and first really caught the public's attention in 2011, when a spate of events sparked such widespread interest that significant effort was made to discredit the phenomenon through the dissemination of fake recordings.

Some, certainly, are hoaxes. That's human nature; we mock that which we do not understand. But the sheer proliferation of 'strange sound events' in recent years, the similarities (with minor differences) between them, and the diversity of the locations they've been recorded in (sometimes more than once), speaks to there being a global reality to this phenomenon. In the course of tracking and reporting these events on SOTT, we've noticed that they tend to come in waves; there can be 'silence' for some time, then 4 or 5 'strange sounds' events occur in disparate locations (perhaps within the same region or continent) in the time span of a week or fortnight. And, as best we can tell, this trend seems to be increasing.

Here is our 'best of' strange sounds summary video, comprising some events from around the world in 2016. Please excuse the occasional foul language - muting or otherwise distorting it would have interfered with the strange sounds themselves. Besides, hearing them curse and swear, you get a real sense of the observers' astonishment!
