2024-07-29 20:35:32 UTC (2024-07-29) · approx. 12:35 PM UTC-8 local
On July 29, 2024 at 20:35 UTC, a magnitude 2.2 shallow crustal earthquake struck 21 km ENE of Barstow, CA, at a depth of 2.8 km and coordinates 34.9443°, -116.8012°.
Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 30.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
