On August 10, 2024 at 21:29 UTC, a magnitude 2.1 shallow crustal earthquake struck 12 km NNW of Aguanga, CA, at a depth of 13.1 km and coordinates 33.5343°, -116.9297°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 22.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
