There are certainly earthquakes associated with volcanic activity but they are usually small and shallow.
Volcanic earthquakes are almost always due to the movement of magma.
When a volcano starts to show some unrest the earthquakes tend to be deep. As the magma batch moves to the surface the earthquakes likewise migrate upward. Most of these earthquakes are probably too small to make it into the news other than in the local area. Ultimately they are all due to the subduction process, but other than that they are not really related.
