Asia is one of the largest landmass in the world and has a longest coastline and prone to the volcanic earthquakes and the occurrence of Tsunamis.
Explanation:
As tsunamis are triggered by an earthquake and the volcanic eruption is caused by the underwater explosion along with with the landslides and the other mass movements the abrupt deformation of the seafloor and sudden movements of the seawater are caused.
Such as the example of the japan was an 8.9 magnitude of the earthquake that triggers huge killer waves and that caused the displacement of the ocean bodies.
As Asia cover about 44,579,000 km square about 30% of the earth landmass it has large parts of the land are deformed by the presence of the mountain ranges and the formation of volcanic arc and islands near the lands thus has a rugged topography of the ocean floor.
