M4.5 Earthquake near Drake Passage — August 28, 2025
2025-08-28 18:58:40 UTC (2025-08-28) · approx. 2:58 PM UTC-4 local
On August 28, 2025 at 18:58 UTC, a magnitude 4.5 shallow crustal earthquake struck near Drake Passage, at a depth of 10.0 km and coordinates -60.3491°, -61.8384°. This earthquake was detected by 32 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
