2020-06-20 11:57:59 UTC (2020-06-20) · approx. 9:57 PM UTC+10 local
On June 20, 2020 at 11:57 UTC, a magnitude 5.0 shallow crustal earthquake struck 264 km NNW of Saipan, Northern Mariana Islands, at a depth of 12.6 km and coordinates 17.5164°, 145.1047°.
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.
