How many volcanoes in the world?
Ian Stoddard
Ian,
According to the recent Smithsonian Institution book, VOLCANOES OF
THE WORLD there are about 1511 volcanoes that are considered to be
active. There are many other dramatic looking volcanoes - such as
Arthur's Seat in Edinburg that are ancient and dead. And there are many
volcanoes on the ocean floor (especially in the western Pacific) and on
Mars and Venus!
