Geological Summary

This symmetrical Argentinian stratovolcano is the source of well-preserved lava flows of Holocene age from summit and flank vents (de Silva and Francis, 1991). Cerro Peinado is one of the youngest volcanoes in the region. The upper part of the cone is blanketed by pyroclastic material. Possible pyroclastic-flow lobes extend to the NW and N. An apron of pristine lava flows that extends to 6 km were erupted from the main cone and from vents on the flank, including a prominent ESE-flank vent. It is surrounded by small fields of older cinder cones, maars, and lava flows, located along N-S-trending faults, which are related to the Salar de Antofalla and Antofagasta volcanic fields.

The Global Volcanism Program is not aware of any Holocene eruptions from Peinado. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Peinado page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Lighter-colored pyroclastic material blankets the summit of Cerro Peinado, and a possible pyroclastic-flow deposit descends the right-hand flank. This symmetrical Argentinian stratovolcano, one of the youngest in the region, is the source of well-preserved lava flows of Holocene age from summit and flank vents. An apron of pristine lava flows surrounds the volcano and was erupted from the main cone and from vents on the flank, including a prominent ESE-flank vent.

WOVOdat WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
EarthChem EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).
MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
