Cause of mysterious booms remains elusive Posted on Wednesday, February 20, 2013 at 11:39 am The mystery remains unsolved. It’s been several days since any major reports of rumbling or loud booms have been made in Hamblen County and authorities don’t know if the multiple enigmatic subterranean vibrations are related. “It remains unclear at this time. There are several different possibilities, but we can not be conclusive about a definitive answer,” said Hamblen County Emergency Management Agency Director Chris Bell. “There’s not enough information and data available at this time to make a 100-percent conclusive answer.” Essentially, the research into the rumblings by Memphis scientists has ended. However, Bell added that there might exist a possibility for a state grant that would allow further research into the cause of the incidents. “If we continue to have theses type circumstances, we have the opportunity to request through the state for more equipment to be brought in to study what’s happening during these time periods,” said Bell. The incidents were first reported in the Meadows subdivision in West Morristown on Jan. 21. Residents in the Meadows reported more rumbling and booming sounds Feb. 2. In the Meadows, the initial incident lasted around two-and-a-half hours with one deputy describing it as sounding – and feeling – “like a grenade had gone off underground.” Last Tuesday, around 4 p.m., throughout Hamblen County and Morristown citizens reported a loud boom and the ground shaking followed by two to three more incidents. Around 9 p.m., another event occurred, again throughout eastern parts of Hamblen County and Morristown. Gary Patterson, PhD., a scientist with the Center for Earthquake Research and Information, said their team studied several heliograph charts and data from stations located in East Tennessee. Patterson explained that because the readings tend to occur at the same time every day, they don’t appear to be natural. “We can’t rule it out yet, but because the time periods are grouped, they don’t appear to be earthquakes,” he said. “The energy seems to be coming from somewhere between Morristown and the Virginia border.” If the rumblings are man-made, it may take some time for authorities to discover the source. Authorities have also said that fracking, an explosion, sewer repair work, area construction, the Tennessee Valley Authority, weather, the military and the zinc mines in Jefferson City are likely not causes. -By Aletheia Davidson, Tribune Staff Writer

It was in yesterday's paper that the booms were heard again in the Sulfur Springs area sometime around 9:10 a.m.
I looked in the paper online, but it didn't have the article listed there. This is getting a little scary!
It would appear Morristown has developed something of a pattern. When the temperature drops and there’s a significant amount of precipitation; the unexplained rumbling booms return.
Around 7:20 a.m. Friday morning, residents surrounding the areas of Debi Circle, Springvale Road, Bacon Lane and Scenic Drive reported hearing a loud boom, followed by the ground shaking.
As has been the case, there was no proof of explosion, leaving it to be added to a lengthening list of enigmatic booms that have plagued Morristown for about two years now.
Morristown-Hamblen County Emergency Management Agency Director Chris Bell said he has spoken with the state and said he was told to amass information so they can try to find a pattern and begin a possible investigation.
Residents who hear, and/or feel, the “booms” should email Bell at firstname.lastname@example.org and include their address, the time of the incident, their name and contact information and a description of the sound and any effects.
Having dealt with the unexplained phenomenon for two years, it would appear that the booms occur when there is a drop in temperature and the county has had a lot of rain.
Reports of the mysterious booms began in January 2013, in the Meadows subdivision around 1 a.m. Days before the first reports, the area experienced major rains and snow. At the time, Dr. Robert Hatcher, Professor of Structural Geology and Tectonics at the University of Tennessee said much of the geography of Morristown is what scientists refer to a karst, which is characteristic of sinkholes and caves. Scientists came to the area in February 2013, and ruled out several possible causes, including fracking, earthquakes, explosions, sewer repair work, construction, aircrafts and the mines in Jefferson County, but a definitive explanation was elusive.
