A volcano is active if itâs currently erupting or showing signs of unrest. The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10,000 years. A volcano finally goes extinct when thereâs no lava supply in the magma chamber beneath the volcano.
As of 2013, the following are considered Earth's most active volcanoes: 1  KÄ«lauea, the famous Hawaiian volcano, has been in continuous, effusive eruption since 1983, and has the longest-observed lava lake. 2  Mount Etna and nearby Stromboli, two Mediterranean volcanoes in almost continuous eruption since antiquity.
