2020-10-16 15:25:23 UTC (2020-10-16) · approx. 7:25 AM UTC-8 local
On October 16, 2020 at 15:25 UTC, a magnitude 2.3 shallow crustal earthquake struck 4 km E of Cold Springs, Nevada, at a depth of 7.1 km and coordinates 39.6782°, -119.9217°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
