How many volcanoes have erupted each year? by Lily

I learned a lot more about volcanos like how many erupt each year (60-70). I also learned about the most damaging volcano. Some volcanos can erupt big time and some can not. I changed my answer because on one website ,it said Yellowstone's volcano can cause the most damage, but I learned later that Mt. Pinatubo can cause the most damage. When I was thinking what to research I thought of  volcanoes. I also learned that without volcanos we would not have the Hawaiian islands.  That is my research.
