M4.6 Earthquake in the Azores Islands region — June 6, 2020
2020-06-06 21:42:26 UTC (2020-06-06) · approx. 7:42 PM UTC-2 local
On June 6, 2020 at 21:42 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Azores Islands region, at a depth of 10.0 km and coordinates 36.3043°, -33.7249°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
