M5.3 Earthquake in the Balleny Islands region — June 13, 2025
2025-06-13 04:26:03 UTC (2025-06-13) · approx. 3:26 PM UTC+11 local
On June 13, 2025 at 04:26 UTC, a magnitude 5.3 shallow crustal earthquake struck in the Balleny Islands region, at a depth of 10.0 km and coordinates -62.0394°, 162.1379°. This earthquake was detected by 42 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
