2022-06-17 23:47:52 UTC (2022-06-17) · approx. 3:47 PM UTC-8 local
On June 17, 2022 at 23:47 UTC, a magnitude 3.1 shallow crustal earthquake struck 19km SSW of Lamont, CA, at a depth of 13.1 km and coordinates 35.1083°, -119.0065°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 747 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 87 m — a useful intuition for the size of the slip patch on the fault.
