How often do volcanos erupt?
Joe
Dear Joe,
In an average year about 20-25 volcanoes erupt. I'd guess that about
10-15 might be erupting right now. Some volcanoes, like Kilauea and
Sakurajima, erupt nearly constantly. To see a list volcanoes that erupted
in 1994 have a look in Volcano Facts
in Learning about Volcanoes.
