M5.0 Earthquake south of the Mariana Islands — September 14, 2020
2020-09-14 08:07:10 UTC (2020-09-14) · approx. 6:07 PM UTC+10 local
On September 14, 2020 at 08:07 UTC, a magnitude 5.0 shallow crustal earthquake struck south of the Mariana Islands, at a depth of 10.0 km and coordinates 10.5269°, 145.8497°.
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.
