2020-07-24 20:23:00 UTC (2020-07-24) · approx. 5:23 AM UTC+9 local
On July 24, 2020 at 20:23 UTC, a magnitude 4.0 shallow crustal earthquake struck 97 km ENE of Amahai, Indonesia, at a depth of 18.8 km and coordinates -3.0783°, 129.7620°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
