M3.4 Earthquake in the Guam region — March 17, 2022
2022-03-17 20:09:37 UTC (2022-03-17) · approx. 6:09 AM UTC+10 local
On March 17, 2022 at 20:09 UTC, a magnitude 3.4 intermediate depth earthquake struck in the Guam region, at a depth of 144.5 km and coordinates 13.9605°, 144.6472°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
