Nevado Chachani volcano towers north of the international airport at Arequipa, Perú. The massive, 360 km² volcanic complex includes a group of stratovolcanoes forming the horizon in this view, an older lava dome complex, and a younger SW-flank shield volcano. The dark hills in the left-center foreground are the distal margins of viscous lava flows from the Pampa de Placio, the SW-flank shield volcano. Volcanism has migrated to the west, and this marks the most recent activity of the Nevado Chachani complex.

Explosive activity, which had begun on May 28, 1990, was continuing in 1995. Sabancaya volcano was constructed on the saddle between Ampato (left) and Hualca Hualca volcanoes. Ashfall from Sabancaya in 1991, which accumulated on Hualca Hualca, caused increased melting of glaciers that produced mudflows down the Majes river drainage north of the volcano.

Photo by Ch. Pattry, 1990 (courtesy of Alberto Parodi I.) The Sabancaya volcanic complex, viewed here from the east, consists of 6288-m Ampato volcano (left), the eroded 6025-m-high Hualca Hualca volcano (right), and Sabancaya volcano proper (center), which was constructed on the saddle between the two older volcanoes. The two older centers have produced morphologically youthful lava flows, but 5967-m-high Sabancaya is the only center to have erupted in historical time.

Nevado Coropuna, Perú's highest and largest volcano, is a massive ice-covered volcanic complex with at least a half dozen summit cones scattered over a 12 x 20 km area. The 6377-m-high summit (left), seen here from the south, is located at the NW end of the complex. Deep, steep-walled canyons surrounding the volcano give it an impressive topographic relief of more than 4000 m over a horizontal distance of 15 km. Several young Holocene lava flows descend the NE, SE, and western flanks.

Photo by Norm Banks, 1988 (U.S. Geological Survey). The cinder cones at the center and upper right, surrounded by a prominent field of lava flows, are located in the Andahua valley, known locally as the "Valley of the Volcanoes." The large 60 x 60 km scoria cone and lava field contains extremely youthful lava flows, some of which may be only a few hundred years old. The volcanic field was reported to have been active during the time of the Incas. Lava flows have repeatedly dammed the Río Andagua valley, and an existing small lake was impounded by the youngest lavas.

Photo by Norm Banks, 1988 (U.S. Geological Survey). Glaciated Sara Sara volcano is in the center of this 22 July 2019 Sentinel-2 satellite image (N is at the top). A 15-km-long lava flow is visible on the eastern flank, with clear levees along the flow boundary. It is the westernmost young volcano in Peru and has produced intermittent explosive activity for less than 2 million years.

Satellite image courtesy of Copernicus Sentinel Data, 2019. The Río Chillos on the NW side of El Misti volcano has excavated a steep-walled canyon that cuts the lower flanks of the volcano. The NW flank of El Misti is somewhat dissected, in contrast to smoother slopes on other sides. Prevailing winds have distributed a thick ashfall blanket to the NE that mantles the distal margins of youthful lava flows.

Photo by Norm Banks, 1987 (U.S. Geological Survey). An ash-bearing plume rises above Sabancaya volcano in this photo taken from the NE, possibly in October, 1988. Voluminous steam plumes, some with dark, basal "rooster-tails," were observed to have risen 0.5-1 km above the summit on June 22, 1988. The northern flank of Ampato volcano rises at the far right.

Photo by Minard Hall, 1988 (Escuela National Politecnica, Quito). Volcán Ubinas, seen here from the west, is Perú's most active volcano. A small, 1.2-km-wide caldera that cuts the top of Ubinas gives it a truncated appearance. The upper slopes of the stratovolcano steepen to nearly 45 degrees. The steep-walled, 150-m-deep caldera contains an ash cone with a 500-m-wide funnel-shaped vent that is 200-m deep. Holocene lava flows are visible on the volcano's flanks, but historical activity, documented since the 16th century, has consisted of intermittent minor explosive eruptions.

Photo by Norm Banks, 1988 (U.S. Geological Survey). Huaynaputina is a relatively inconspicuous volcano that was the source of one of the largest historical eruptions of the central Andes in 1600 CE. The volcano has no prominent topographic expression. This view is from the east into a 2.5-km-wide complex caldera that is breached widely to the east. Three ash cones, one of which can be seen in the shadow at the right-center, are located on the floor of the caldera. Light-colored ash deposits from the 1600 eruption can be seen mantling the caldera rim.

Photo by Oscar González-Ferrán (University of Chile). The elongated Coropuna volcanic massif is seen here from the NE. The dark lava flow descending the NE flank at the left center is one of several youthful lava flows that overlie roughly 11,000-year-old glacial moraines. The morphology of this flow and others on the SE and western flanks suggest that they are very young and postdate activity from the summit craters.

Photo by Norm Banks, 1988 (U.S. Geological Survey). 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). The Sabancaya volcanic complex consists of Sabancaya volcano proper (foreground), the older 6288-m-high Ampato volcano (background), and 6025-m Hualca Hualca volcano. Sabancaya, viewed here from the NE, is constructed on the saddle between the two older volcanoes. It is the youngest of the three Holocene volcanic centers and the only one to have erupted in historical time. An extensive 15-km-wide apron of trachytic and dacitic lava flows surrounds the 5967-m-high volcano. Records of historical eruptions date back to 1750.

Photo by Norm Banks, 1988 (U.S. Geological Survey). The glacier-capped Nevado de Chachani volcanic complex lies immediately north of the city of Arequipa. The central part of the 6057-m-high complex contains multiple vents along an arcuate line. Pleistocene lava domes form the glacier-covered northern end of the complex in this NASA image. A prominent lava-flow complex at the bottom-center part of the image with fresh-looking flow levees was erupted from the 8-km-wide lava shield of Pampa de Palacio of late-Pleistocene to possibly Holocene age.

NASA Landsat 7 image (worldwind.arc.nasa.gov) The isolated Cerro Nicholson scoria cone in Peru is shown in this July 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 6 km across). The monogenetic cone has a summit crater with a diameter of around 200 m.

Strong explosions were observed at intervals of 20-30 minutes during a visit to the volcano on 13-19 April. The explosions lasted about a minute and produced 3-4 km high ash plumes.

Photo by Pierre Vetsch, 1991. The Nevado de Chachani volcanic complex, seen here from the SW near the village of Yura, consists of a 360 km² group of Pleistocene lava domes, a stratovolcano, and a shield volcano. The central, 6057-m-high Nevado Chachani complex contains multiple vents along an arcuate line, including a well-defined summit crater at the western end. Cerro La Horqueta (left horizon) may represent the latest activity from Nevado Chachani, after which activity migrated to the 8-km-wide Holocene lava shield of Pampa de Palacio on the south side.

Photo by Norm Banks, 1988 (U.S. Geological Survey). Volcanoes of three ages can be seen in this aerial view across northern Perú. The eroded, 6093-m-high Solimana volcano (foreground) has not erupted since the Pleistocene, but has an active fumarole. It is located NW of the younger Coropuna volcano (upper right), which has produced major flank lava flows during the Holocene. The three-peaked Sabancaya volcanic complex (upper left) includes the historically active cone of Sabancaya proper, which is flanked on the left by Hualca Hualca volcano and on the right by Ampato volcano.

Towering 5980-m-high Tacora, the northernmost volcano of Chile, lies near the border with Perú and is a twin volcano with Chupiquina. Tacora is seen here from the SE. Although there have been uncertain reports of historical eruptions, and solfataric and fumarolic activity has been reported on the east side, Holocene eruptions from Tacora have not been documented.

Photo by Oscar González-Ferrán (University of Chile). A lava flow at Quimsachata scoria cone is visible in this October 2020 Planet Labs satellite image monthly mosaic (N is at the top). The flow erupted about 11,500 years ago and is approximately 4.7 km in the NW-SE direction. The smaller lava flow directly to the north was erupted from the Oroscocha lava dome about 6,400 years ago. These are the northernmost young volcanic centers in Perú.

Residents living near the volcano reported an explosive eruption from Sabancaya that began on May 28, 1990. Initially, several explosions occurred per day, producing plumes to about 2 km height. Activity intensified on June 4, and by the 8th explosions occurred at intervals of 5-10 minutes and ashfall covered a radius of 20 km. More-or-less constant ash emission continued until 1998.

Photo by Guido Salas, 1990 (University of San Antonio, Arequipa). Tacora, the northernmost volcano of Chile, rises to the NW above the steep-walled Allane valley. The 5980-m-high Tacora lies near the border with Perú and is a twin volcano with Chupiquina, hidden behind Tacora in this view. Although there have been uncertain reports of historical eruptions, and solfataric and fumarolic activity has been reported on the east side, Holocene eruptions have not been documented. The Arica to La Paz railway transects the plateau on the northern side of the Allane valley.

Photo by Lee Siebert, 2004 (Smithsonian Institution). The glacier-covered Nevado Firura volcanic complex is seen here from the NW. It consists of a 10-12 km long, NE-SW-trending cluster of small stratovolcanoes. The highest peak is 5500-m Nevado Firura itself (right center). Other volcanoes of the complex, including 5191-m-high Cerro Soncco Orcco, Cerro Jahsaya, and Antapuna are located to the SW, left of this view.

The Cerro Keyocc cone of the northern Huambo volcanic field is shown below the center of this July 2020 Planet Labs satellite image monthly mosaic (N is at the top; the image is approximately 13 km across). The cone produced a lava flow that traveled down the south of the cone then W, then N. The flow has many lobate breakout flows with pressure ridges along the surfaces.

Satellite image courtesy of Planet Labs Inc., 2020 (https://www.planet.com/). The 6377-m-high summit of Coropuna volcano, Perú's highest, forms the peak at the center of the photo. It lies north of a 20-km-long E-W chain of peaks forming the ice-covered massif. The present glacial icecap covers an area of 130 km² and descends to 5800 m on the south and 5300 m on the north. Dramatic lateral moraines from older glaciers extend up to 10 km and reach below 4500 m. Steep canyons on the volcano's flanks create among the world's highest topographic relief, up to 4000 m over a horizontal distance of 15 km.
