The Global Volcanism Program is not aware of any Holocene eruptions from Cotacachi. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Cotacachi page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
There is no Deformation History data available for Cotacachi.
There is no Emissions History data available for Cotacachi.
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. Maps are not currently available due to technical issues.
There are no samples for Cotacachi in the Smithsonian's NMNH Department of Mineral Sciences Rock and Ore collection.

WOVOdat
Single Volcano View Temporal Evolution of Unrest Side by Side Volcanoes |
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.
GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. |
| IRIS seismic stations/networks | Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Cotacachi. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice. |
| UNAVCO GPS/GNSS stations | Geodetic Data Services map from UNAVCO showing the location of GPS/GNSS stations from all available networks (permanent or temporary) within a radius of 20 km from the given location of Cotacachi. Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player. |
| Large Eruptions of Cotacachi | 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). |
| 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). |
