How often do volcanos erupt?

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.
