What states are in the New Madrid fault line?
While not as well known for earthquakes as California or Alaska, the New Madrid Seismic Zone (NMSZ), located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois, is the most active seismic area in the United States, east of the Rocky Mountains.
Does TN have a fault line?
“Earthquakes frequently occur in Tennessee because the state’s eastern and western areas sit along seismic zones where earthquake activity happens more frequently – the East Tennessee Seismic Zone and the New Madrid Seismic Zone (NMSZ).
Will the New Madrid fault erupt?
NEW MADRID, Mo. — The last major earthquakes along the fault happened in December 1811 and in 1812, but University of Arkansas professor Gregory Dumond said scientists can’t predict when the next one will happen. “We can give you a percent chance of it maybe happening, but that’s about it,” he said in a 2019 interview.
What Lake in Tennessee was formed by an earthquake?
Reelfoot Lake State Park
Reelfoot Lake State Park is located in the northwest corner of Tennessee and is noted for its fishing, boating and wildlife viewing. The 15,000 acre lake was created by a series of violent earthquakes in 1811-1812 that caused the Mississippi River to flow backwards for a short period of time, creating Reelfoot Lake.

Does East Tennessee have earthquakes?

Is the New Madrid Fault line still active today?
The zone is active, averaging more than 200 measured seismic events per year. The New Madrid Fault extends approximately 120 miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through Mew Madrid and Caruthersville, following Interstate 55 to Blytheville, then to Marked Tree Arkansas.
