M5.0 Earthquake near northern East Pacific Rise — August 28, 2026
2026-08-28 02:39:17 UTC (1 hour ago) · approx. 7:39 PM UTC-7 local
On August 28, 2026 at 02:39 UTC, a magnitude 5.0 shallow crustal earthquake struck near northern East Pacific Rise, at a depth of 10.0 km and coordinates 8.4191°, -103.4604°. This earthquake was detected by 52 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
