There are two likely possibilities A subduction zone or a divergent zone, ( a hot spot is also a good possibility.

Explanation:

When an ocean plate is pushed and pulled under a continental plate the melted sediments and water push up through the crust above the converging plate interaction. This can create volcanos.
A new volcano pushed up in a Mexican corn field creating a volcano where done had previously existed.

Where the earth is splitting open at a divergent plate boundary volcanos are formed by the magma coming to the surface. A new volcanic island was formed near Iceland by this mechanism. One day there was ocean the next day a steaming volcano.

Hot spots also form new volcanos. The Hawaiian islands have been formed by a series of volcanos that have been formed by the hot spot below the Pacific Ocean Crust. The Big Island has five volcanic peaks. The three in the north part of the island are no longer active. The small volcano in the far south of the island is presently erupting. As the Pacific plate moves over the hot spot it is likely a new volcano will form.
