I was wondering if the quakes would trigger volcano eruptions.

Yes. Japan is at a majot plate boundary.

The quake generates a lot of friction between the tectonic plates, and the resulting heat will mobilize the magma. If there's enough heat, the magma will eventually erupt.

This volcano erupted in January, but there may have been smaller quakes at that time.
