Question

The area where one plate is being pushed beneath another plate, when these zones
are located in or near the ocean, the tsunami hazard will be higher. The Pacific
Northwest and Alaska are located along these zones.​

Answer 1

Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.
