A micro earthquake centered near Ridgely shook parts of the Reelfoot Lake area Wednesday afternoon.
The 2.5 magnitude event occurred at 1:40 p.m. five miles east-southeast of Ridgely at a hypocentral depth of three miles, according to the Center for Earthquake Research and Information (CERI).
It was centered eight miles southwest of Hornbeak and nine miles south-southwest of Samburg.
A day earlier, a 1.5 magnitude event was recorded at 12:23 in the morning about six miles north-northwest of Dyersburg.
The area is part of the New Madrid fault system or the New Madrid seismic zone — a series of faults beneath the continental crust in a weak spot known as the Reelfoot Rift. It cannot be seen on the surface.
The fault system extends 150 miles southward from Cairo, Ill., through New Madrid, Mo., and Caruthersville, Mo., down through Blytheville, Ark., to Marked Tree, Ark., according to CERI. It dips into Kentucky near Fulton and into Tennessee near Reelfoot Lake and extends southeast to Dyersburg.
It crosses five state lines and crosses the Mississippi River in at least three places.
CERI, established in 1977, serves the University of Memphis by facilitating interdisciplinary research and education and the public by providing authoritative scientific education and information.
