M5.2 Earthquake in the Revilla Gigedo Islands region — November 16, 2025
2025-11-16 21:44:09 UTC (2025-11-16) · approx. 2:44 PM UTC-7 local
On November 16, 2025 at 21:44 UTC, a magnitude 5.2 shallow crustal earthquake struck in the Revilla Gigedo Islands region, at a depth of 10.0 km and coordinates 19.5027°, -109.0053°. This earthquake was detected by 64 seismic stations with good location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
