On August 22, 2025 at 02:16 UTC, a magnitude 7.5 shallow crustal earthquake struck near 2025 Southern Drake Passage Earthquake, at a depth of 10.0 km and coordinates -60.3187°, -61.9221°. The earthquake was reported felt by 15 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.7 (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 101 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 876, making it one of the more significant events of the week.

Physical scale: An earthquake of magnitude 7.5 releases seismic energy equivalent to roughly 2.7 megatons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 90 km — a useful intuition for the size of the slip patch on the fault.
