Welcome to your weekly seismic update from across the state, brought to you by the Alaska Earthquake Center, where we monitor ...

Megathrust earthquakes occur when stress at subduction zones is released, causing significant plate slippage. These events disrupt long-term tectonic changes, complicating modeling efforts.

At least 2,237 magnitude 3 or larger earthquakes were tallied in Alaska and the Aleutian Island region ... Alaska features one of the longest subduction zones in the world and will always lead ...

Aside from the danger they pose, such earthquakes disrupt the slow, long-term changes occurring at subduction zones. The cycle of sudden earthquakes and slow plate movement makes it difficult for ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants ...

The result of this collision is something scientists call a “subduction zone” deep within the Earth’s mantle. Because these subduction zones are too deep to measure directly, researchers typically use ...

One of these hidden plates was found underneath the western Pacific. However, there is no evidence of plate subduction—a geological process in which one tectonic plate is forced beneath another ...

There are small earthquake swarms every couple of years on average in the subduction zone along the Aleutian chain. A swarm occured in May about 350 miles (550 kilometers) east of Sunday's ...
