M4.7 Earthquake near central East Pacific Rise — March 6, 2025
2025-03-06 02:59:58 UTC (2025-03-06) · approx. 7:59 PM UTC-7 local
On March 6, 2025 at 02:59 UTC, a magnitude 4.7 shallow crustal earthquake struck near central East Pacific Rise, at a depth of 10.0 km and coordinates -5.7903°, -109.3245°. This earthquake was detected by 86 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
