|An explosive eruption about 2900 years ago produced widespread tephra and pyroclastic surges. Subsequently a group of four dacitic lava domes was constructed within Cuicocha caldera. This marks the latest known activity from the caldera. The eastern two domes are seen here from the SE rim of the caldera. The lava domes form two forested islands in the center of the 3-km-wide caldera.

|Sharp-peaked Cotacachi stratovolcano rises above the caldera lake of Cuicocha volcano. The northern caldera wall truncates the flank of the heavily eroded Cotacachi. The caldera was formed during powerful explosive eruptions about 3100 years ago that produced 4.8 cu km of pumice-rich pyroclastic flows and airfall tephra that blanket the surrounding countryside.

|Scenic lake-filled Cuicocha caldera is located at the southern foot of the sharp-peaked Pleistocene Cotacachi stratovolcano. The caldera was created about 3100 years ago and contains a cluster of intra-caldera dacitic lava domes that form two islands in the large lake. A pre-caldera Cuicocha lava dome is situated on the east side of the lake (right). Pyroclastic-flow deposits cover wide areas around the volcano. The northern caldera rim truncates the heavily eroded slopes of Cotocachi volcano.

|The scenic lake-filled Cuicocha caldera is located at the southern foot of the sharp-peaked Pleistocene Cotacachi stratovolcano (top center) about 100 km north of Quito. Farmer's fields encroach on the rim of the 3-km-wide caldera, which was created during a major explosive eruption about 3100 years ago. Dacitic lava domes form two forested islands in the caldera lake. Pyroclastic-flow deposits from the caldera-forming eruptions cover wide areas in now populated areas below the low-rimmed caldera.

|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 Cuicocha||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).|
