On November 27, 2025 at 23:10 UTC, a magnitude 3.0 shallow crustal earthquake struck 17 km N of Santa Barbara Is., CA, at a depth of 8.8 km and coordinates 33.6193°, -119.0333°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 511 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 73 m — a useful intuition for the size of the slip patch on the fault.
