On September 10, 2026 at 13:38 UTC, a magnitude 4.8 shallow crustal earthquake struck 255 km N of Puerto Ayora, Ecuador, at a depth of 10.0 km and coordinates 1.5461°, -90.6694°. This earthquake was detected by 13 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
