When one is found the date, time, location, and intensity are recorded. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. 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. 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. 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. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter. ![]() Hazard maps found on this website should not be used for emergency purposes. This site is for educational purposes related to volcanic hazard maps. ![]() In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments. 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. 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. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore. 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. Catalog number links will open a window with more information. The following 20 samples associated with this volcano can be found in the Smithsonian's NMNH Department of Mineral Sciences collections, and may be availble for research (contact the Rock and Ore Collections Manager).

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. This volcano is located within the Archipiélago de Colón (Galápagos), a UNESCO World Heritage property. An eruption of uncertain nature was reported in 1928 (Catalog of Active Volcanoes of the World). The fresh, unvegetated lava flows that cover the SE and N flanks appear to have been erupted during the past few thousand or few hundred years (McBirney and Williams, 1969). It is a shield volcano with numerous young cones and lava flows originating from NNW-trending fissures. The elongated island of Pinta is the northernmost of the active Galápagos volcanoes.
