Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Misti, El
El Misti, Perú's best known volcano, is a symmetrical stratovolcano that towers above the city of Arequipa. It is seen here from the west at the margin of Arequipa's airport. The modern symmetrical cone has a small, 1.5-km-wide summit caldera containing nested craters. It caps an older Pleistocene volcano that collapsed, producing debris avalanches to the west and SW. El Misti's most recent activity has been dominantly pyroclastic. Historical eruptions date back to the 15th century. Photo by Norm Banks, 1988 (U.S. Geological Survey).

El Misti is a symmetrical andesitic stratovolcano with nested summit craters that towers above the city of Arequipa, Peru. The modern symmetrical cone, constructed within a small 1.5 x 2 km wide summit caldera that formed between about 13,700 and 11,300 years ago, caps older Pleistocene volcanoes that underwent caldera collapse about 50,000 years ago. A large scoria cone has grown with the 830-m-wide outer summit crater. At least 20 tephra-fall deposits and numerous pyroclastic-flow deposits have been documented during the past 50,000 years, including a pyroclastic flow that traveled 12 km to the south about 2000 years ago. The most recent activity has been dominantly pyroclastic, and strong winds have formed a parabolic dune field of volcanic ash extending up to 20 km downwind. An eruption in the 15th century affected nearby Inca inhabitants. Some reports of historical eruptions may represent increased fumarolic activity.
