On October 10, 2023 at 00:13 UTC, a magnitude 5.6 deep-focus earthquake struck 60 km SE of Embarcación, Argentina, at a depth of 571.4 km and coordinates -23.6084°, -63.6903°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 1.1 (weak). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 256 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 483, placing it among routine seismic activity. The nearest populated place is Yuto (population 7,732).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 km — a useful intuition for the size of the slip patch on the fault.
