A M3.8 earthquake hit right in the Eastern Tennessee Seismic Zone on January 20 2020. Use our IBC Seismic Design Categories map to easily obtain the seismic design category and spectral response acceleration parameter (Section 1613 of the IBC 2015) for any location in the contiguous United States, Puerto Rico and Alaska. Eastern Tennessee Seismic Zone Alabama sits on the edge of the Eastern Tennessee seismic zone, which extends from south west Virginia to … The Southern Appalachian Seismic Zone, a seismic region stretching from northwestern Georgia, through Tennessee and into northeastern Alabama, was hit by a swarm of 5 earthquakes on February 11, 2020. Your assistance informing the local communities is appreciated.
