M4.7 Earthquake near northern Mid-Atlantic Ridge — May 28, 2024
2024-05-28 17:18:28 UTC (2024-05-28) · approx. 2:18 PM UTC-3 local
On May 28, 2024 at 17:18 UTC, a magnitude 4.7 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 10.7765°, -42.7582°. This earthquake was detected by 36 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
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.
