Felt by 1 person across nearby locations.
On May 10, 2022 at 08:42 UTC, a magnitude 5.4 deep-focus earthquake struck 17 km WSW of El Hoyo, Argentina, at a depth of 568.7 km and coordinates -27.1007°, -63.3928°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 1.0 (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 172 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity. The nearest populated place is Yerba Buena (population 50,783).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
