M5.2 Earthquake near central East Pacific Rise — May 8, 2021
2021-05-08 04:13:57 UTC (2021-05-08) · approx. 9:13 PM UTC-7 local
On May 8, 2021 at 04:13 UTC, a magnitude 5.2 shallow crustal earthquake struck near central East Pacific Rise, at a depth of 10.0 km and coordinates -4.6701°, -105.4171°.
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.
