Mysterious 'Unknown Phenomena' Caused Loud Explosion, Ground To Shake in Tennessee

Local authorities have been left stumped after investigating numerous reports of a loud explosion in Montgomery County, Tennessee, over the weekend.

Residents living in locations across the county heard what appeared to be an explosion at around 9:50 p.m. CDT on Saturday.

Clarksville Police Department has said that its 911 Dispatch Center received "numerous calls" about the incident "across many parts of Montgomery County."

People as far and wide as Greenwood Avenue, Dunbar Cave, Hilldale, Rosewood Drive, Cumberland Drive and Madison Street have reported hearing an explosion.

Some people have said that they felt the ground shake, such was the strength of the apparent impact.

However, despite investigating the matter alongside the Clarksville Fire Department, Montgomery County Sheriff's Office and emergency medical services, its source is yet to be identified.

Furthermore, there have been no reports of any property damage, nor of any injuries.

An earthquake has also been deemed unlikely.

The most recent earthquake registered by the United States Geological Survey in or around Tennessee was a 1.5 magnitude quake that was detected more than 100 miles away near Ridgely, shortly after midnight on Thursday.

An earthquake of that magnitude isn't strong enough to be felt by people.

Peachers Mill resident Heather Risacher Rooney managed to capture the phenomenon in video footage.

With no explanation forthcoming, locals have been speculating about the source of the noise.

One of the most popular theories is that it came from Fort Campbell, which straddles the border between Clarksville and Hopkinsville in Kentucky and is home to the 101st Airborne Division.

However, Clarksville Police Department has said that Fort Campbell was on a "four-day weekend due to the Labor Day holiday" at the time of the explosion, and that it did not appear to be "conducting any type of training or exercise."

"Currently, this seems to be some sort of unknown phenomena until someone reports actual damage," the police department wrote in a post on Facebook.

Some people have lightheartedly compared the mystery to the infamous UFO incident at Roswell in 1947, when Roswell Army Air Field announced that it had found a "flying disc" on a ranch in the area.

The Army quickly backpedaled and said that the object was a weather balloon, but not before the prospect of extra-terrestrial contact had captured the public's imagination.

Others have compared it to the unusual incident in Clintonville in March 2012, where locals heard a series of unexplained noises for four days.

The phenomena were later attributed to a swarm of small earthquakes that were amplified by the ground beneath the city.
