M4.7 Earthquake near northern Mid-Atlantic Ridge — June 28, 2020
2020-06-28 07:32:53 UTC (2020-06-28) · approx. 4:32 AM UTC-3 local
On June 28, 2020 at 07:32 UTC, a magnitude 4.7 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 17.6406°, -46.4829°.
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.
