2026-09-28 13:30:32 UTC (3 hours ago) · approx. 5:30 AM UTC-8 local
On September 28, 2026 at 13:30 UTC, a magnitude 3.2 shallow crustal earthquake struck 275 km W of Indianola, California, at a depth of 10.0 km and coordinates 41.1377°, -127.4517°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
