M4.5 Earthquake southwest of Africa — July 30, 2024
2024-07-30 17:34:22 UTC (2024-07-30) · approx. 6:34 PM UTC+1 local
On July 30, 2024 at 17:34 UTC, a magnitude 4.5 shallow crustal earthquake struck southwest of Africa, at a depth of 10.0 km and coordinates -52.2949°, 13.4469°. This earthquake was detected by 9 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
