M5.2 Earthquake near central East Pacific Rise — September 20, 2023
2023-09-20 14:45:27 UTC (2023-09-20) · approx. 7:45 AM UTC-7 local
On September 20, 2023 at 14:45 UTC, a magnitude 5.2 shallow crustal earthquake struck near central East Pacific Rise, at a depth of 10.0 km and coordinates -4.5602°, -105.6816°. This earthquake was detected by 279 seismic stations with good location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
