I dont even know what is the problem on the question..but here it is,volcanic earthquake is caused by the eruption in a nearby volcano caused by the flow of lava underneath the surface,meanwhile the tectonic earthquake occurs because of two plate tectonics colliding and "brushing" each other that causes the crust to shake..the part of the earth that frequently produce earthquake is around the pacific ring of fire because it is composed of neighboring volcanoes and fault lines
