M4.9 Earthquake near Rat Islands, Aleutian Islands, Alaska — February 14, 2026
2026-02-14 07:10:02 UTC (2026-02-14) · approx. 7:10 PM UTC+12 local
On February 14, 2026 at 07:10 UTC, a magnitude 4.9 intermediate depth earthquake struck near Rat Islands, Aleutian Islands, Alaska, at a depth of 116.7 km and coordinates 52.0072°, 178.3880°. This earthquake was detected by 112 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Alaska, a region characterized by Pacific Plate subduction beneath the North American Plate, producing frequent megathrust and crustal earthquakes along the Aleutian arc. The nearest mapped fault system is the Aleutian megathrust. View all earthquakes in Alaska.
