M4.6 Earthquake near southern East Pacific Rise — October 24, 2025
2025-10-24 20:22:03 UTC (2025-10-24) · approx. 12:22 PM UTC-8 local
On October 24, 2025 at 20:22 UTC, a magnitude 4.6 shallow crustal earthquake struck near southern East Pacific Rise, at a depth of 10.0 km and coordinates -24.5383°, -115.9846°. This earthquake was detected by 79 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
