|Lake-filled Crater Hill on the western side of St. Paul is one of many craters dotting the island. Reindeer (caribou) can be seen wading along the shores of the lake. St. Paul is the largest of the Pribilof Islands and consists of a 110 sq km area of coalescing small basaltic shield volcanoes capped by a central cinder cone. The Fox Hill lava flow at the far western end of the island is estimated to be only a few thousand years old.

|Crater Hill on the western side of St. Paul is one of many pyroclastic cones dotting the island. The crater, which contains an elongated lake, is seen here from the NE. St. Paul, the largest of the Pribilof Islands, consists of a 110 sq km area of coalescing small basaltic shield volcanoes capped by a central cinder cone. The Fox Hill lava flow at the far western end of the island is estimated to be only a few thousand years old.

|A Space Shuttle image of St. Paul Island shows Northeast Point at the upper right, Reef Point at the bottom-center, and Southwest Point at the left. Snow-covered Big Lake lies SW of Northeast Point, Bogoslof Hill near the center of the island, and Rush Hill is the cone along the NW coast. Rush Hill produced lava flows from NE-trending fissures. The 110 sq km island is the largest of the Pribilof Islands and contains more than a dozen basaltic cinder cones and associated lava flows.

|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 St. Paul Island||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).|
