|The small, but spectacular 2.5-km-wide Kaguyak caldera,seen here from the west, is filled by a lake that lies more than 550 m below the caldera rim. A post-caldera lava dome extends into the lake on the SW side and another dome forms a small island in the center of the lake. The caldera is unglaciated and the voluminous caldera-forming deposits have been radiocarbon dated at at 5800 years ago. A large pre-caldera lava dome forms the high point on the east caldera rim. The broad valley of Big River descends to Shelikof Strait at the upper right.

|Fourpeaked volcano, the 2104-m-high glacier-covered peak at the upper left is one of a group of poorly known volcanoes NE of Katmai National Park. Much of the volcano's surface is hidden beneath Fourpeaked Glacier; the few exposed outcrops are lava flows interlayered with volcanic agglomerate. Rocks near the summit are extensively hydrothermally altered. The age of the volcano is not known. In the foreground is the dramatic young, 2.5-km-wide Kaguyak caldera, filled by a lake and 3 lava domes.

|Snow and ice covers the surface of the lake filling Kaguyak caldera in this view from the NW. The caldera was formed during a voluminous eruption about 5800 years ago that produced pyroclastic flows that reached Shelikof Strait. Two lava domes, one large and the other just sticking above the center of the lake were formed some time after the caldera-forming eruption, following formation of a shallow lake.

|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 Kaguyak||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).|
