A magnitude 5.5 earthquake strikes Alaska’s remote Aleutian Islands as the largest event in a 14-quake swarm, occurring in the seismically volatile Rat Islands subduction zone capable of magnitude 8+ megathrust events.
A magnitude 2.1 earthquake at 80 km depth strikes near Cantwell, Alaska, just 73 km from the 2002 M7.9 Denali Fault rupture zone, offering scientists data on ongoing regional stress patterns.
A week-long swarm of 24 earthquakes, including a shallow M2.6 tremor near Kodiak Island, highlights persistent seismic unrest along the Alaska-Aleutian subduction zone, capable of magnitude 7+ ruptures.
