2023-11-15 19:20:45 UTC (2023-11-15) · approx. 11:20 AM UTC-8 local
On November 15, 2023 at 19:20 UTC, a magnitude 2.7 shallow crustal earthquake struck 13 km SE of Pinnacles, CA, at a depth of 7.9 km and coordinates 36.4593°, -121.0343°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 175 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 45 m — a useful intuition for the size of the slip patch on the fault.
