2026-07-16 06:10:31 UTC (2026-07-16) · approx. 10:10 PM UTC-8 local
On July 16, 2026 at 06:10 UTC, a magnitude 2.6 shallow crustal earthquake struck 30 km ESE of Somes Bar, CA, at a depth of 38.7 km and coordinates 41.2287°, -123.1722°.
Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 138 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 40 m — a useful intuition for the size of the slip patch on the fault.
