Answer:HOPE IT HELPS
Explanation:Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again. Every time the rock cracks it makes a small earthquake.

Earthquakes due to volcanoes are caused by the movement of magma. They are felt when volcano is directly beneath or near the surface. The magma exerts pressure on the rocks which induce cracking the rock. Then the magma fills into the crack and starts building pressure again. Every time the rock cracks, it makes a small earthquake. These earthquakes are usually too weak to be felt but can be detected and recorded by sensitive instruments.
