2021-04-04 23:53:59 UTC (2021-04-04) · approx. 5:53 PM UTC-6 local
On April 4, 2021 at 23:53 UTC, a magnitude 2.0 shallow crustal earthquake struck 7 km WSW of Townsend, Tennessee, at a depth of 12.7 km and coordinates 35.6490°, -83.8345°.
Physical scale: An earthquake of magnitude 2.0 releases seismic energy equivalent to roughly 17.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 15 m — a useful intuition for the size of the slip patch on the fault.
