When two oceanic plates collide, the denser oceanic plate will subduct beneath the other, forming island arcs. One example would be the Solomon Islands.

*Note that the Hawaii island chain is NOT formed by convergent plate boundaries but a hotspot which is located right under Hawaii, or the Pacific plate. The Pacific plate moves and the volcanoes on it becomes extinct when it is cut off from the magma source, and the magma from the hotspot rises, forming a new volcano and island.

when plates collide they also form fold mountains and cause earthquakes

What happens when two plates carrying oceanic collide?

When two oceanic crusts collide, the older plate is forced under the younger one and is pulled under it, forming a subduction zone. This leads to the formation of chains of volcanic islands known as island arcs.
