On July 31, 2024 at 04:11 UTC, a magnitude 5.1 shallow crustal earthquake struck near central East Pacific Rise, at a depth of 10.0 km and coordinates -9.1486°, -109.7407°. This earthquake was detected by 57 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.
