Earth Changes
There are many theories as to what the boom was - cryoseism, earthquake or sonic boom. But none have been definitely proven.
Cryoseism seemed to be the first theory most concluded on social media.
According to Frost Quake's website, a cryoseism is defined as "'a natural phenomenon that occurs when extremely cold temperatures lead to sudden deep freezing of the ground, after it has been saturated with water."
Earth science professor at Tennessee Tech Larry Knox said a cryoseism just wasn't likely.
"As I understand them, cryoseisms occur where the ground is saturated with ground water and temperatures drop suddenly to, or below, zero degrees Fahrenheit. There was a temperature drop on Sunday, but not of that magnitude," Knox said via email. "Also, cryoseisms are generally accompanied by earthquake-like vibrations that are strong enough for people to feel them - no earthquakes were reported as far as I know."
A little-known active stratovolcano erupted in a fiery explosion in the Amazonian Andes of Ecuador known as 'Reventador' in early December. Reventador is Spanish for 'troublemaker'.
Roscoe and a German colleague captured the rumblings and fiery explosions with wide-angle videos using moonlight alone by applying a unique filming technique at a specific rate and sped up the video to show the activity over the course of a three-day period.

Rescuers are using heavy machinery to search for survivors after the landslide on the slopes of Mount Merapi
An avalanche of sand and rock cascaded down the slopes of Mount Merapi in Central Java about 10am (11am Singapore), burying a group of miners digging through the rocks and sand.
"The landslide happened suddenly and immediately buried the miners," disaster mitigation agency spokesman Sutopo Purwo Nugroho said in a statement.
The State Emergency Service (SES) said they had received hundreds of calls for assistance after storms brewed on yesterday afternoon.
A severe thunderstorm warning for damaging winds, heavy rain and large hailstones remains current for much of the state.
More than 30,000 homes properties are still without power, down from about 100,000 around the state last night.
Power was also out in parts of suburban Melbourne but the impact was far less significant.
The weather bureau's Dean Stewart said Melbourne received 20 millimetres of rain within 15 minutes, causing flash flooding in many suburbs.
"The highest wind gust in the state was up at Kilmore Gap to the north of Melbourne - 117 kilometre per hour - but a lot of towns reported gusts over 100kph, [followed by] Wangaratta with 113kph, Bendigo 111kph, Mangalore 107kph, Laverton 98kph," he said.
Scientists used a network of thousands of seismic measurement devices in the largest geological study of its kind, detecting the enormous blob upwelling under Vermont, New Hampshire, and Massachusetts - and possibly elsewhere.
"The upwelling we detected is like a hot air balloon, and we infer that something is rising up through the deeper part of our planet under New England," says geophysicist Vadim Levin from Rutgers University - New Brunswick.

The accident was captured by people in the crowd at the electronic music festival in Esteio near the southern city of Porto Alegre in Brazil.
The fan-caught footage shows the moment when the stage buckles and falls over while a crowd of around 5,000 people watched.

Mount Sinabung volcano spews volcanic ash in Karo, North Sumatera, Indonesia, on Dec. 18, 2017.
Head of Sinabung volcano monitoring post Armen Putra said the latest eruption took place on 13:02 p.m. Western Indonesian Time (WIB), coupled with 303 seconds of tremors around the area.
"Hot clouds were seen rising 2,500 meters to the east-southeast and 3,500 meters to the south," Armed said.
He added the post was hardly able to see the column of smoke and ashes from the eruption as the volcano summit was engulfed by thick haze. The wind blew mildly during the eruption, bringing the ashes to the west-south direction, he added.

Syracuse was blanketed with several inches of snow and people were out shoveling and snow blowing Dec. 13, 2017.
At Hancock International Airport, the official measuring station for Syracuse, 8.9 inches of snow fell. The old record for Dec. 13 was 5.9 inches, set in 1951.
Syracuse wasn't the snowiest place in Central New York, which saw waves of lake effect snow sweep through. Phoenix had 14.4 inches Wednesday, according to the weather service. Camillus had 10.5 inches.
Tug Hill got even more. Redfield, in Oswego County, had 21.4 inches on Wednesday. Since Sunday, 44.3 inches has fallen there.
Syracuse has had 16.1 inches since Sunday.
Comment: A rare recent blast of winter weather has dusted Louisiana with snow, shutting down much of the state. There has also been record snowfall in Houston, Texas and Alabama. Across the U.S. all 50 states have recorded snow two weeks ahead of Christmas.
Meanwhile just over a week ago, Alaska recorded one of the most extreme snowfall rates on record - when an incredible 10 inches of snow piled up in one hour. In the end, 40 inches of heavy wet snow accumulated in 12 hours.
