|Descabezado Grande (center) and Cerro Azul (middle right), seen here from the NW, are the most prominent features of a large volcanic field. The most active of the two large stratovolcanoes is 3810-m-high Cerro Azul. Quizapú, a vent that formed in 1846 on the northern flank of Cerro Azul, was the source of one of the world's largest explosive eruptions of the 20th century in April 1932. The eruption created a 600-700 m wide crater and ejected 9.5 cu km of dacitic tephra. The only historical eruption of Descabezado Grande took place later in 1932.

|The gaping crater of the 1932 Quizapú eruption (left-center) lies below the summit of Cerro Azul stratovolcano. Cerro Azul was constructed to the south of its twin volcano Descabezado Grande, where this photo was taken. Steep-sided Cerro Azul has a 500-m-wide summit crater that is open to the north. Quizapú was the source of one of the world's largest explosive eruptions of the 20th century in 1932. This eruption created a 600-700 m wide, 150 m deep crater and ejected 9.5 cu km of dacitic tephra.

There are no samples for Cerro Azul in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection.
|DECADE Data||The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the MAGA Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.|

|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 Cerro Azul||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).|
