GATLINBURG, Tenn. (AP) — Five small earthquakes rattled an area near the Great Smoky Mountain National Park in east Tennessee, the U.S. Geological Survey reported Tuesday. These earthquakes occurred in an area known as the East Tennessee Seismic Zone (ETSZ). Small earthquakes of this magnitude are common in East Tennessee. Earthquakes frequently occur in Tennessee because the state’s eastern and western areas sit along seismic zones (the East Tennessee Seismic Zone and the New Madrid Seismic Zone respectively) where earthquake activity happens more frequently. HVO recorded over 220 earthquakes for the entire 24-hour period. The Reelfoot Lake basin, Tennessee, is structurally complex and of great interest seismologically because it is located at the junction of two seismicity trends of the New Madrid seismic zone. It's understood to be one of the most active quake zones in the United States. NEW DATA TO HELP UNDERSTAND THE PALEOSEISMIC HISTORY OF THE EAST TENNESSEE SEISMIC ZONE. The Eastern Tennessee Seismic Zone (ETSZ), a zone of small seismic faults stretching from northeastern Alabama to southwestern Virginia, may have generated earthquakes of … To better understand the structure at this location, a 7.5-km-long seismic reflection profile was acquired on roads along the southern margin of Reelfoot Lake. The depth of the earthquake was 15.7 km according to the USGS.

Typically, a high seismic hazard zone is nearest a seismic zone where there are more earthquakes, and a lower seismic hazard zone is farther away from a seismic zone. The epicenter was 14.4 miles southwest of Knoxville, Tennessee. Another point of confusion is that the California Geological Survey has two sets of maps with the names “ Earthquake Hazards Zones ” and “ Earthquake Fault Zones (Alquist-Priolo) ”. The East Tennessee fault line, which runs from Chattanooga, through Knoxville and into North Carolina, is only part of a larger seismic zone, and it's pretty active, Whaley said. Unique in Tennessee, at a depth below the northwestern part of the region, is the New Madrid seismic zone, capable of generating devastating earthquakes. The smaller earthquake was reported as part of the Eastern Tennessee Seismic Zone, “one of the most active earthquake areas in the Southeast,” the USGS said.
