2024-11-07 09:00:06 UTC (2024-11-07) · approx. 7:00 AM UTC-2 local
On November 7, 2024 at 09:00 UTC, a magnitude 5.0 intermediate depth earthquake struck in the South Sandwich Islands region, at a depth of 119.2 km and coordinates -56.2193°, -27.4481°. This earthquake was detected by 67 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.
