M5.1 Earthquake near central Mid-Atlantic Ridge — July 23, 2026
2026-07-23 06:29:57 UTC (2 hours ago) · approx. 3:29 AM UTC-3 local
On July 23, 2026 at 06:29 UTC, a magnitude 5.1 shallow crustal earthquake struck near central Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 8.5099°, -39.3528°. This earthquake was detected by 47 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
