On April 14, 2025 at 22:56 UTC, a magnitude 2.3 shallow crustal earthquake struck 6 km NNW of Big Bear Lake, CA, at a depth of 7.3 km and coordinates 34.2908°, -116.9395°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 47.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 24 m — a useful intuition for the size of the slip patch on the fault.
