OK, so most volcanoes occur in the Ring of Fire, along tectonic plates edges esp. in the Pacific. Those are also earthquake prone areas.
But plates must be formed and destroyed somehow, yes?
Well we have a super-volcano waiting to burst forth like a giant zit … (nevermind, we have a lot of volcanic activity at Yellowstone). There was a huge earthquake at New Madrid Missouri not too long ago.
