|The NW rim of Diamante caldera in the center of the image rises above the caldera floor in the foreground. The caldera was formed during voluminous rhyolitic explosive eruptions about 450,000 years ago that produced ashflows that extended radially more than 100 km from the caldera, covering much of the Central Valley of Chile and extending into Argentina. The conical snow-capped peak on the center horizon beyond rugged intervening peaks of the Andes is San José volcano.

|Maipo volcano, seen here from the west, partially fills the Pleistocene Diamante caldera. The floor of the large 15 x 20 km caldera, which formed about 0.45 million years ago during an eruption that produced a 450 cu km ignimbrite, is visible below Maipo. The 5264-m-high basaltic-andesite stratovolcano has a relatively simple structure, but has a flank rhyodacitic lava-dome complex and pyroclastic cones on its eastern flank. Lava flows from these cones extend into Laguna Diamante on the eastern side of the caldera.

|Conical Maipo volcano rises above the floor of Diamante caldera in this NASA Space Shuttle view (with north to the top). A series of flank vents on the eastern side of the volcano produced lava flows that give the western shoreline of Laguna Maipo and irregular outline; a lava flow in 1826 blocked drainages on the caldera floor, forming the lake. The 15 x 20 km Diamante caldera was formed during a major explosion eruption about 450,000 years ago.

|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.|
|Large Eruptions of Maipo||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).|
|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.|
|MODVOLC Thermal Alerts||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.|
|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).|
