Subduction zone is one of the most critical tectonic phenomena on Earth. Its correlation to the formation of volcanic arc, deep earthquake, and basins attract the minds of geologists. Profound role of subduction zone emerges as methods in geophysics reveal the structure and composition of materials deep beneath the Earth’s surface.

Principally, subduction zone is the area of the Earth where two plates colliding and the one sinking inside the Earth. The primary cause of subducting slab beside compression is density. [[Crust]] with higher density tends to move inside the Earth. According to the types of involved crust, subduction zone has two separate types: island-arc and active [[continental margin]] (ACM). Island-arc only involves oceanic crust, while ACM encompasses both continental and oceanic crust.
