M4.4 Earthquake in the Mariana Islands region — July 3, 2022
2022-07-03 20:36:07 UTC (2022-07-03) · approx. 6:36 AM UTC+10 local
On July 3, 2022 at 20:36 UTC, a magnitude 4.4 intermediate depth earthquake struck in the Mariana Islands region, at a depth of 85.3 km and coordinates 19.0996°, 146.0862°.
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.
