M4.8 Earthquake near northern Mid-Atlantic Ridge — May 19, 2024
2024-05-19 15:33:24 UTC (2024-05-19) · approx. 12:33 PM UTC-3 local
On May 19, 2024 at 15:33 UTC, a magnitude 4.8 shallow crustal earthquake struck near northern Mid-Atlantic Ridge, at a depth of 10.0 km and coordinates 30.4627°, -41.8865°. This earthquake was detected by 84 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
