M4.6 Earthquake near northern Mid-Atlantic Ridge — January 10, 2022
2022-01-10 23:35:34 UTC (2022-01-10) · approx. 8:35 PM UTC-3 local
On January 10, 2022 at 23:35 UTC, a magnitude 4.6 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 28.3430°, -43.5883°.
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.
