2026-10-16 03:44:27 UTC (33 min ago) · approx. 7:44 PM UTC-8 local
On October 16, 2026 at 03:44 UTC, a magnitude 3.3 intermediate depth earthquake struck 8 km NE of Gazelle, CA, at a depth of 77.8 km and coordinates 41.5718°, -122.4505°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 116 m — a useful intuition for the size of the slip patch on the fault.
