M4.7 Earthquake near southeast central Pacific Ocean — August 24, 2022
2022-08-24 19:32:31 UTC (2022-08-24) · approx. 1:32 PM UTC-6 local
On August 24, 2022 at 19:32 UTC, a magnitude 4.7 shallow crustal earthquake struck near southeast central Pacific Ocean, at a depth of 10.0 km and coordinates -30.8104°, -89.9889°. This earthquake was detected by 57 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.
