The Aeolian archipelago in the Tyrrhenian Sea (east of Italy, north of Sicily) is interpreted as a volcanic arc . All of the seven main islands are volcanic in origin. Three volcanoes in the arc are active: Stromboli, Vulcano, and Lipari. Stromboli has been erupting almost continuously for 2,000 years. Vulcano has had numerous explosive eruptions, the most recent in 1888. The most recent eruption on Lipari, the largest island in the archipelago, was about 1,400 years ago.
This photograph, taken from the the summit of Vulcano, looks north to Lipari. Lipari rises from about 6,500 feet (2,000 m) below sea level to about 2,000 feet (600 m) above sea level. Vulcanello, in the middle ground, erupted most recently in 1631. Photograph by Gordon Macdonald, U.S. Geological Survey, (date unknown).
