M5.7 Earthquake 9 km N of San Gabriel, Ecuador — July 25, 2022
2022-07-25 13:33:28 UTC (2022-07-25) · approx. 8:33 AM UTC-5 local
Felt by 8 people across nearby locations. Maximum shaking intensity MMI 7.2 (severe).
On July 25, 2022 at 13:33 UTC, a magnitude 5.7 shallow crustal earthquake struck 9 km N of San Gabriel, Ecuador, at a depth of 2.5 km and coordinates 0.6760°, -77.8293°. The earthquake was reported felt by 8 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.2 (severe). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 81 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 654, making it a moderate-impact event. The nearest populated place is San Gabriel (population 15,112).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
