M3.7 Earthquake in the Maug Islands region, Northern Mariana Islands — April 28, 2024
2024-04-28 20:04:09 UTC (2024-04-28) · approx. 6:04 AM UTC+10 local
On April 28, 2024 at 20:04 UTC, a magnitude 3.7 intermediate depth earthquake struck in the Maug Islands region, Northern Mariana Islands, at a depth of 239.4 km and coordinates 19.5469°, 145.0140°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
