M5.2 Earthquake near northern Mid-Atlantic Ridge — March 30, 2026
2026-03-30 14:43:32 UTC (2026-03-30) · approx. 11:43 AM UTC-3 local
On March 30, 2026 at 14:43 UTC, a magnitude 5.2 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 23.9725°, -45.9699°. This earthquake was detected by 169 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
