A volcano that doesn't erupt is typically classified as a "dormant" or "extinct" volcano. Dormant volcanoes have the potential to erupt in the future but have not done so for a significant period of time, while extinct volcanoes are not expected to erupt again. Examples include the Eiffel Tower in France and the ancient volcanoes found in the Hawaiian Islands that have not shown any activity for thousands of years.
About 60 volcanoes erupt each year.
