M4.7 Earthquake near North Atlantic Ocean — November 8, 2020
2020-11-08 05:01:03 UTC (2020-11-08) · approx. 2:01 AM UTC-3 local
On November 8, 2020 at 05:01 UTC, a magnitude 4.7 shallow crustal earthquake struck near North Atlantic Ocean, at a depth of 10.0 km and coordinates 19.3794°, -42.5797°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
