MORRISTOWN — The Morristown-Hamblen Emergency Management Agency in Morristown is asking residents of the Hamblen County area if they “felt or heard a loud boom” early Tuesday.
In 2013 this was heard quite a bit, and by some members here. The odd thing is last night, around 5:45 EST, we heard a boom that shook the house. All the people on the road were outside asking what that was. I live about 50 miles from Morristown. The people that heard it last night were confined to a small 1 mile or less radius apparently. I called the number in the Knoxnews post and reported it, even though it wasn't this mornings boom. They said they are getting all sorts of calls from the area. Maybe fracking or drilling is starting up again?
Cryoseismic booms, or frost quakes, are caused when frozen water expands quickly in the ground, according to the National Weather Service.
When water runs into the ground and freezes, it expands when the temperature drops dramatically, putting stress on the surrounding soil or rock.
The “explosion” is the result of the pressure being released with a booming sound and slight tremor.
