M4.8 Earthquake near northern East Pacific Rise — December 23, 2020
2020-12-23 00:53:28 UTC (2020-12-23) · approx. 5:53 PM UTC-7 local
On December 23, 2020 at 00:53 UTC, a magnitude 4.8 shallow crustal earthquake struck near northern East Pacific Rise, at a depth of 10.0 km and coordinates 8.2599°, -103.0377°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
