M5.1 Earthquake in the Galapagos Triple Junction region — August 8, 2021
2021-08-08 00:49:32 UTC (2021-08-08) · approx. 5:49 PM UTC-7 local
On August 8, 2021 at 00:49 UTC, a magnitude 5.1 shallow crustal earthquake struck in the Galapagos Triple Junction region, at a depth of 10.0 km and coordinates 2.2217°, -101.3891°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
