M4.5 Earthquake west of the Galapagos Islands — July 14, 2021
2021-07-14 17:46:16 UTC (2021-07-14) · approx. 10:46 AM UTC-7 local
On July 14, 2021 at 17:46 UTC, a magnitude 4.5 shallow crustal earthquake struck west of the Galapagos Islands, at a depth of 10.0 km and coordinates 2.2933°, -97.5969°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
