M5.0 Earthquake east of the Philippine Islands — July 16, 2021
2021-07-16 23:29:19 UTC (2021-07-16) · approx. 8:29 AM UTC+9 local
On July 16, 2021 at 23:29 UTC, a magnitude 5.0 shallow crustal earthquake struck east of the Philippine Islands, at a depth of 10.0 km and coordinates 14.1510°, 128.1657°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
