M4.4 Earthquake in the Mariana Islands region — July 16, 2024
2024-07-16 17:42:47 UTC (2024-07-16) · approx. 3:42 AM UTC+10 local
On July 16, 2024 at 17:42 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Mariana Islands region, at a depth of 10.0 km and coordinates 19.7594°, 147.6290°.
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.
