2024-10-28 21:50:42 UTC (2024-10-28) · approx. 4:50 PM UTC-5 local
On October 28, 2024 at 21:50 UTC, a magnitude 3.9 shallow crustal earthquake struck 70 km WSW of Jipijapa, Ecuador, at a depth of 10.0 km and coordinates -1.5485°, -81.1823°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
