2024-09-24 19:41:59 UTC (2024-09-24) · approx. 2:41 PM UTC-5 local
On September 24, 2024 at 19:41 UTC, a magnitude 3.4 intermediate depth earthquake struck 17 km NNE of Alausí, Ecuador, at a depth of 125.8 km and coordinates -2.0609°, -78.7820°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
