M5.0 Earthquake in the Mariana Islands region — November 27, 2022
2022-11-27 20:52:01 UTC (2022-11-27) · approx. 6:52 AM UTC+10 local
On November 27, 2022 at 20:52 UTC, a magnitude 5.0 shallow crustal earthquake struck in the Mariana Islands region, at a depth of 10.0 km and coordinates 21.4723°, 144.1049°. This earthquake was detected by 90 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
