2024-04-14 19:57:03 UTC (2024-04-14) · approx. 11:57 AM UTC-8 local
On April 14, 2024 at 19:57 UTC, a magnitude 2.9 shallow crustal earthquake struck 17 km SW of Westley, CA, at a depth of -0.3 km and coordinates 37.4253°, -121.3140°.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 362 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 62 m — a useful intuition for the size of the slip patch on the fault.
