M4.8 Earthquake in the Guam region — April 2, 2022
2022-04-02 10:54:10 UTC (2022-04-02) · approx. 8:54 PM UTC+10 local
On April 2, 2022 at 10:54 UTC, a magnitude 4.8 shallow crustal earthquake struck in the Guam region, at a depth of 10.0 km and coordinates 12.7211°, 145.5389°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
