Active volcanoes


Geologists classify volcanoes into three distinct groups: dormant, extinct, and active. Active volcanoes have erupted recently and are expected to continue to erupt again soon. The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10,000 years. A volcano finally goes extinct when there's no lava supply in the magma chamber beneath the volcano. There are approximately 1,500 active volcanoes in the world today and 75 percent of them are located in the Pacific Ring of Fire. On average, 50-70 volcanoes erupt every year.



This is a list of lists of active and extinct volcanoes sorted by country.
