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.

|The area around Volcán Putana is seen from the west in this sketch. Putana is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km. Vigorous fumarolic activity (depicted in this sketch) is visible at the 5890-m-high summit of Putana volcano from long distances. The main edifice consists of accumulated postglacial dacitic lava domes and flows mantling an older pre-Holocene volcano. Young dark-colored flows in this sketch descend the western flanks of the volcano.

|Putana volcano, also known as Jorgencal or Machuca, lies in the center of this Landsat image. Snow-covered areas are deep blue in this image of the N-S-trending volcanic complex, which covers an area of 600 sq km. The main edifice consists of accumulated postglacial dacitic lava domes and flows mantling an older pre-Holocene volcano. The youngest basaltic andesite lava flows are viscous and rarely extend more than 3 km. The prominent fan-shaped lava flow at the upper left originated from a flank vent.

|Volcán Putana, seen here from the west, shows vigorous fumarolic activity at its 5890-m-high summit. Snow forming a thin diagonal line below and to the right of the summit marks a road leading to a sulfur-mining operation at the summit of the volcano. Putana is also known as Jorgencal or Machuca and is part of a large, roughly N-S-trending volcanic complex that covers an area of 600 sq km along the Chile-Bolivia border. Postglacial dacitic lava domes and short, thick lava flows form the main edifice.

A listing of samples from the Smithsonian collections will be available soon.
|Large Eruptions of Putana||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|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.|
