Residents of southern Arizona are baffled by mysterious booms being felt and heard across the southern part of the state, which have caused the ground to shake and pets to tremble. No one seems to have an explanation for the weird occurrences.

The spooky events happened two nights in a row - on Tuesday between 8pm and 8:30pm, and on Wednesday just after 3pm, according to Tucson News Now. It's not just one or two people who have reported the strange booms, as the media outlet says it has been "inundated" with calls, emails and Facebook messages from witnesses.

Describing one of the booms, a resident by the name of Jim Hughson said it "sounded like someone throwing boulders in a huge dumpster. Crazy." He said he heard the boom on the northeastern side of Tucson.

Another resident named Pamela Sutherland said one of the booms "was loud and it shook the house, rattled windows, and everything hanging on the walls. It was enough to make the ground shake and frighten our dog."

BOOM! Mysterious blasts rattling the skies are on the increase around the world - UPDATE at least 64 documented events (VIDEO)

Was it a supersonic aircraft? A meteor? A ground explosion? The end of the world as we know it?

Those are the questions experts and non-experts around the world are asking themselves in recent weeks as curiously loud mystery BOOMS have not only been hear around the world, but felt - shaking buildings and rattling nerves from Alabama to Michigan, Idaho to California, Russia to Denmark.

The Alabama boom last Tuesday at 1:39 CST was heard and felt through 11 counties, but an earthquake event has been ruled out.

The day after Alabamans were shaken by that incident, something similar occurred in Idaho. No explanation has been forthcoming from law enforcement officials there.

Mysterious boom heard in Idaho Panhandle

Multiple people reported hearing a loud boom over the Lewiston-Clarkston Valley around 11 p.m. Wednesday, but its cause and location are unknown.

Of the numerous reports on social media and to law enforcement, the sound was described as being similar to a sonic boom - the sound a jet makes when it breaks the sound barrier. People reported hearing it in Clarkston, Lewiston and the Orchards.

The Whitcom Emergency Dispatch Center, which covers several area municipalities, received 15 calls about the noise. Lewiston police Sgt. Rick Fuentes said LPD dispatch received at least five calls that ranged in location from Lewis-Clark State College to Burrell Avenue to North Lewiston. Clarkston Police Commander Josh Daniel said a patrol officer was outside of his vehicle and heard the noise, but did not see anything. The officer reported hearing the noise near 13th and Bridge streets, but couldn't pinpoint a location.

A loud boom - that some say shook them to their core - has people in Cape Coral concerned, confused, and curious about the cause.

"All of a sudden there was this huge boom," said JoAnn Navarre. "My daughter and I both screamed, and we jumped."

Navarre lives on NW 31st Street in Cape Coral. She said the commotion happened around 6 p.m. Sunday.

"We thought maybe something hit the house; something hit nearby. We didn't know if something exploded; we thought people were hurt," Navarre said.

After it happened, she went outside to inspect and found many of her neighbors doing the same thing.

Mysterious loud 'boom' heard across North Alabama - NASA unsure of origin

(WBMA) -- Shortly after 1:40 p.m., a loud 'boom' was heard across North Alabama in Blount, Jefferson, Walker, Cullman, Talladega, Calhoun, Clay, Winston, Randolph, Tuscaloosa, and St. Clair counties.

It's the sound everybody is talking about. So much so, Trey Cochran wrote a song about it:

Alabamians flocked to Twitter, with many reporting the event shook their homes.

Lincoln resident Dawn Stanton described it as "...a propane tank just exploding. I looked and I didn't see nothin' sailing through the air."

The National Weather Service in Birmingham hypothesized the sound originated from an aircraft sonic boom or a meteorite from the Leonid shower.

NASA's Bill Cooke says the origin of the mysterious boom still remains unclear but shut down the NWS' theory of a Leonid shower meteroite.

Cooke says 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 analyze new data in hopes of determining the cause of the 'boom.'

ABC 33/40 has reached out to Maxwell Air Force Base to see if a pilot could have broken the sound barrier with a training exercise.

UPDATE: San Diego rocked by a loud boom and shaking; USGS reports it was not an earthquake

San Diego residents have reported loud booms and sensations of shaking. The US Geological Survey said there were no signs of an earthquake, but an independent group did confirm seismic activity.

Residents described experiencing the boom from Alpine to El Cajon, Carmel Valley, National CIty, Eastlake and as far south as Tijuana in Mexico.

"Yeah, [I'm in San Diego] currently and every one in my job heard the [boom] and then felt a shake [afterwards], we thought something had crashed or something," wrote a poster to KNSD's website.

Fifteen minutes outside of San Diego, Luis Hernandez told KNSD that he felt the ground begin to shake. Hernandez said his friends felt it too and he described it as an earthquake.

Comment: UPDATE: Mexico has a possible explanation for this event (if you believe it). Strange Sounds reports:
So what the heck in Mexico?

The official explanation is the following:


In English, it says:
'We inform that the event occurred this morning at 11:56 a.m. Pacific Time, WAS NOT AN EARTHQUAKE. The sensors of the Seismic Network of the CICESE recorded vibrations that are believed to be related to a meteorological phenomenon generated when hot and cold air masses clash together. This violent collision can produces a BOOM that can make the windows vibrate. Analyses of seismic stations of Tijuana show that the event isn't similar to an earthquake.'
OFFICIALS have already used the same explanation (brutal clash between a cold and a warm front) to explain the mysterious apparition of light columns in the sky of Argentina on October 24, 2017:

Mysterious column of light appears over Argentina.
Of course, residents are now questioning this OFFICIAL answer. There were also trainings at Camp Pendleton.

So what's going on? Are they testing a new kind of weather weapon? In the mean time GET READY!
The question is: Why is it that no one considered the possibility of a bolide entering the atmosphere? Is it because falling rocks are scary when they become something more than shooting stars?

Mystery booms heard in North Carolina, Michigan and Queensland

Mystery booms seem to be occurring with increasing frequency lately, with booms being heard just this week in North Carolina and Michigan. In both cases, authorities have been left baffled by what might be behind these earth-shaking noises which seem to emanate from the sky itself. This unexplained phenomenon is host to a wide variety of explanations including gas escaping vents deep within the Earth, anomalous meteorological events, sonic booms from tests of secret military aircraft, UFOs of course, and meteorites exploding in the atmosphere. While most of these eerie thunderous noises go unexplained, a recent mystery boom in Australia might have a simple, cosmic - and terrifying - explanation.

Death from above.

The boom was heard by residents throughout the Cairns region of Queensland, Australia marking the second time in two months that southern Australia has been rocked by anomalous explosions in the sky. The boom occurred around 10:30 pm on Saturday, October 7th and was reportedly so loud that it shook houses in the area.

A Cairns resident checked out the Australian boom and sent a video to the Cairns Post of a possible crater; no sign of a meteorite, just an ash-filled hole in the ground.
