On May 19, 2024 at 22:53 UTC, a magnitude 5.0 shallow crustal earthquake struck in the South Sandwich Islands region, at a depth of 36.3 km and coordinates -57.7049°, -25.2221°. This earthquake was detected by 82 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in South Sandwich Islands, a region characterized by the South Sandwich Trench, one of Earth's most remote subduction zones.
