Geological Summary

The small isolated cone of Rudakov occupies the Tokotan Isthmus on the Sea of Okhotsk coast of central Urup Island. The 532-m-high basaltic-andesite stratovolcano lies between Petr Shmidt ridge and Krishtofovich Ridge and is capped by a 700-m-wide, funnel-like crater containing a 300-m-wide lake. The age was considered to be late Pleistocene or early Holocene (Gorshkov, 1970).

The Global Volcanism Program is not aware of any Holocene eruptions from Rudakov. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Rudakov page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Rudakov.

The small isolated cone on the Tokotan Isthmus adjacent to the Sea of Okhotsk (left) near the center of this Landsat image is Rudakov volcano. The 542-m-high basaltic-andesite stratovolcano lies between Petr Shmidt ridge (upper right) and Krishtofovich Ridge (lower left) in central Urup Island and is capped by a 700-m-wide, funnel-like crater containing a 300-m-wide lake visible in this image.

WOVOdat 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.
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).
MODVOLC - HIGP MODIS Thermal Alert System 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.
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.
