2021-05-27 15:18:26 UTC (2021-05-27) · approx. 7:18 AM UTC-8 local
On May 27, 2021 at 15:18 UTC, a magnitude 3.0 shallow crustal earthquake struck 15km SSW of Trona, CA, at a depth of 6.5 km and coordinates 35.6318°, -117.4118°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 445 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 69 m — a useful intuition for the size of the slip patch on the fault.
