IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Irruputuncu

Steam rises from the fumarolically active southern summit crater of Irruputuncu, a small stratovolcano that straddles the Chile/Bolivia border. Irruputuncu, seen here from the WSW, was constructed within the collapse scarp of a Holocene debris avalanche whose deposit extends to the SW. Levees of viscous lava flows down the western flank of an edifice that was constructed within this scarp are seen at the lower left. The first unambiguous historical eruption from Irruputuncu took place in November 1995. Photo by José Naranjo, 2001 (Servico Nacional de Geologica y Mineria).
