What are the tectonic hazards associated with a destructive plate margin?

Tectonic hazards are hazard events that occur as a result of tectonic activity. There are two forms of destructive plate margins: subductive and collision. A collision plate margin occurs when two continental plates collide into each other. As neither plate can sink, both plates buckle upwards, forming fold mountains. This can result in earthquakes. A subductive plate margin occurs when an ocean plate collides into a continental plate. The denser oceanic plate is forced to subduct beneath the continental plate. The subducted oceanic plate melts in the mantle, resulting in magma rising to the surface that forms a composite volcano. The volcanic eruptions can be violent, and earthquakes can occur too.
