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 ...

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

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 ...

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 ...

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 ...
