You might be surprised to know that there are more than 1500 volcanoes that have erupted during the Holocene era. Which country has the most? We're number one! The U.S. is tops on the list of the nations with the most volcanoes. Russia comes in second, although this list will never be the subject of a competition. Of course, it has to do with land area, so bigger nations would be expected to have more volcanoes. But that's not the only criteria.
The Ring of Fire that encircles the Pacific Ocean – which stretches up the west coast of the Americas, around and across to Asia, looping down to the east of Japan, before overwhelming much of Indonesia and the Philippines and whipping around Australasia – boasts the most, with 452.
This is why Indonesia, despite its diminutive size, has the third most volcanoes in the world, at 139. Likewise, the small islands of Japan, which is fourth with 112. Chile (also on the Ring of Fire, on the cusp of the South American plate) is fifth, with 104.
