NASHVILLE, Tenn. (WKRN) — Earthquakes in Tennessee aren’t in headlines every day.
Last week, Tennessee recorded several earthquakes. While the quakes were relatively small, researchers now closely monitoring the data. The Center for Earthquake Research and Information ( CERI ) at the University of Memphis recorded as many as seven quakes between Monday and Wednesday.

Each earthquake took place along the New Madrid fault line . The highest was a magnitude three near Missouri.
“The New Madrid zones, on occasion, will do a cluster of small earthquakes and then go back to the normal seismicity, basically, of a small earthquake every week or so and usually they’re under magnitude two,” Dr. Kent Moran, a research associate with CERI, told News 2.
Researchers also say it’s unlikely these earthquakes were foreshocks to something bigger.
but clustered earthquakes don’t happen often. The last time was more than four years ago.
