M5.3 Earthquake in the Revilla Gigedo Islands region — December 21, 2022
2022-12-21 16:54:24 UTC (2022-12-21) · approx. 9:54 AM UTC-7 local
On December 21, 2022 at 16:54 UTC, a magnitude 5.3 shallow crustal earthquake struck in the Revilla Gigedo Islands region, at a depth of 10.0 km and coordinates 19.4737°, -108.6682°. This earthquake was detected by 181 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
