On September 15, 2026 at 23:45 UTC, a magnitude 4.5 intermediate depth earthquake struck 17 km WNW of Palora, Ecuador, at a depth of 155.8 km and coordinates -1.6157°, -78.0940°. This earthquake was detected by 53 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

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.
