What is relationship among the location of volcanues, earthquake epicenter, and mauntain ranges?

The relationship among the location of volcanoes, earthquake epicenter, and mountain range is they all are the result of tectonic movement.

Explanation:

A mountain range forms when two tectonic plates of the same strength collide and no one gets over another they crumple and folds to form a mountain.

When two tectonic plates collide a results in a strong vibration called an earthquake and the point where exactly two tectonic plates collided is called the epicenter of the earthquake.

The volcano formed when two one thick and another thin tectonic plate collide the first one gets over another together.  The magma below find an escape and comes out to the surface known as volcano eruption.

Hence,  we can say that all three are related by their origin is the by-product o of tectonic collision.
