2020-11-03 15:18:59 UTC (2020-11-03) · approx. 1:18 AM UTC+10 local
On November 3, 2020 at 15:18 UTC, a magnitude 4.8 shallow crustal earthquake struck 160 km ESE of Saipan, Northern Mariana Islands, at a depth of 10.0 km and coordinates 14.9071°, 147.2132°.
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.
