M5.0 Earthquake north of Ascension Island — August 10, 2020
2020-08-10 23:25:14 UTC (2020-08-10) · approx. 10:25 PM UTC-1 local
On August 10, 2020 at 23:25 UTC, a magnitude 5.0 shallow crustal earthquake struck north of Ascension Island, at a depth of 10.0 km and coordinates -3.9010°, -12.3642°.
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.
