M5.3 Earthquake near northern East Pacific Rise — July 13, 2023
2023-07-13 03:29:59 UTC (2023-07-13) · approx. 8:29 PM UTC-7 local
On July 13, 2023 at 03:29 UTC, a magnitude 5.3 shallow crustal earthquake struck near northern East Pacific Rise, at a depth of 10.0 km and coordinates 10.0272°, -104.1235°. This earthquake was detected by 72 seismic stations with good location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
