When a destructive boundary of two tectonic plates occurs the oceanic crust sinks underneath the continental crust as it is more dense, the oceanic crust then melts in the subduction zone and becomes magma in the mantle, this increases the pressure in the mantle and causes the magma to shoot up the volcano shaft and burst out of the top, this is an eruption

What causes the difference between quiet and exploses eruptions?

How often does a volcano explode?
It depends, a volcano can erupt once and never erupt again. Or, a volcano can erupt multiple times a day.
Why do you think earthquakes are likely to occur at the same time when the volcano is about to erupt?
