How many times does a volcano erupt per 100 years?

Dear reader,
That depends on the volcano and the 100 year interval you are interested
in. Some volcanoes can go hundreds, thousands, or even hundreds of
thousands of years between eruptions. So, it depends which 100 years you
pick on whether or not there will be an eruption. Some volcanoes can
erupt almost continuously for more than 100 years, like Kilauea from
1823-1924. Some volcanoes might erupt many times in 100 years. For
example, Mauna Loa in Hawaii has erupted 16 times in the last 100 years.
Other volcanoes, like Lassen in California, have only erupted once in the
last 100 years.
