M4.4 Earthquake in the Mariana Islands region — May 19, 2022
2022-05-19 20:29:05 UTC (2022-05-19) · approx. 6:29 AM UTC+10 local
On May 19, 2022 at 20:29 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Mariana Islands region, at a depth of 10.0 km and coordinates 18.4216°, 147.2021°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
