M4.3 Earthquake 24 km S of Mina, Nevada — December 1, 2020
2020-12-01 23:43:08 UTC (2020-12-01) · approx. 3:43 PM UTC-8 local
On December 1, 2020 at 23:43 UTC, a magnitude 4.3 shallow crustal earthquake struck 24 km S of Mina, Nevada, at a depth of 4.8 km and coordinates 38.1727°, -118.0703°. The nearest populated place is Hawthorne (population 3,269).
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
