M4.6 Earthquake in the Mariana Islands region — November 10, 2022
2022-11-10 05:21:13 UTC (2022-11-10) · approx. 3:21 PM UTC+10 local
On November 10, 2022 at 05:21 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Mariana Islands region, at a depth of 29.4 km and coordinates 18.5751°, 147.0779°. This earthquake was detected by 48 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
