M7.0 Earthquake near 2025 Hubbard Glacier Earthquake — December 6, 2025
2025-12-06 20:41:49 UTC (2025-12-06) · approx. 11:41 AM UTC-9 local
Felt by 1,058 people across a wide area. Maximum shaking intensity MMI 8.4 (violent).
On December 6, 2025 at 20:41 UTC, a magnitude 7.0 shallow crustal earthquake struck near 2025 Hubbard Glacier Earthquake, at a depth of 10.3 km and coordinates 60.3127°, -139.5412°. The earthquake was reported felt by 1,058 peopleacross a wide area, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.4 (violent). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 270 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1384, making it one of the most significant global earthquakes in recent days. The nearest populated place is Haines Junction (population 1,148).
Physical scale: An earthquake of magnitude 7.0 releases seismic energy equivalent to roughly 477 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 41 km — a useful intuition for the size of the slip patch on the fault.
