|The beautiful caldera lake of Billy Mitchell provides a dramatic setting for unvegetated Bagana volcano, one of the most active in Papua New Guinea. The Solomon Sea can be seen in the distance to the SW. Two major explosive eruptions from Billy Mitchell, one about 900 and the other about 370 years ago, produced pyroclastic-fall deposits that cover most of the northern half of Bougainville Island and pyroclastic-flow and -surge deposits that extend 25 km to the eastern coast. The younger eruption may have been responsible for formation of the summit caldera.

|Billy Mitchell is a small pyroclastic shield truncated by a small 2-km-wide caldera containing a beautiful caldera lake. It is seen here from the north, with the eroded forested Reini volcano on the center horizon and neighboring Bagana volcano at the upper right. Billy Mitchell has been the source of some of the largest Holocene eruptions of Papua New Guinea. Two major explosive eruptions, one about 900 years ago and the other about 370 years ago, produced pyroclastic-fall deposits that cover most of the northern half of Bougainville Island.

|Much of the left side of this NASA image with north to the upper left is covered by volcanic products from Tore volcano in the Emperor Range on NW Bougainville Island. The Tore massif lies to the left of the light-colored area at the center of the image, Balbi volcano. Two Pleistocene ignimbrites from Tore formed a broad fan that extends the coastline to the west (lower left). The dark-colored caldera lake of Billy Mitchell volcano is at the right, above an ash plume originating from Bagana volcano.

|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 Billy Mitchell||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).|
