Felt by 65 people across nearby locations. Maximum shaking intensity MMI 4.4 (moderate).
On July 14, 2022 at 22:30 UTC, a magnitude 5.7 intermediate depth earthquake struck 11 km SW of Samborondón, Ecuador, at a depth of 73.0 km and coordinates -2.0369°, -79.7903°. The earthquake was reported felt by 65 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.4 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 168 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 534, placing it among routine seismic activity. The nearest populated place is Palestina (population 9,364).
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.
