This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|Zheltovsky volcano, seen here from Diky Greben volcano to its SW, was constructed during the last 8000 years within a 4 x 5 km caldera truncating an earlier Pleistocene edifice. A late-Holocene explosive eruption formed a 1.6-km-wide summit crater that was largely filled by four lava domes, the latest of which forms the present 1953-m-high summit. Only a few eruptions are known in historical time. The largest, in 1923, produced explosive activity and a lava flow down the SE flank that partially flowed into the summit crater.

|The maar crater in the foreground was created during an eruption in 1901 on the NE flank of Ilyinsky volcano. Light-colored tephra deposits from the maar-forming eruption cap the rim of the crater and blanket the flanks of the volcano. At the end of the eruption, lava was extruded on the floor of the 200-m deep, 1-km-wide crater. Snow-streaked Zheltovsky, another historically active stratovolcano, rises to the NE.

|Zheltovsky stratovolcano rises across a broad valley NE of Ilyinsky volcano. The flat shelf on the right flank of Zheltovsky is the eastern rim of a 4 x 5 km, largely buried Pleistocene caldera. The dark mass seen halfway down the left horizon is a lava dome constructed over the western rim of the caldera. The western rim of a smaller, late-Holocene caldera forms the break in slope on the left side just below the summit lava-dome complex. The crater in the foreground is a NE-flank maar of Ilyinsky that formed in 1901.

|The circular caldera at the center of this Space Shuttle image with north to the upper right is Pizrak caldera. The dark-colored cone within the caldera is Kell, a small Holocene stratovolcano. This remote volcanic complex in southern Kamchatka consists of three partially nested 3-5 km wide calderas containing lava domes and small stratovolcanoes, of which 900-m-high Kell volcano is the highest. The large stratovolcano at the lower left, immediately south of Kell, is historically active Zheltovsky volcano.

A listing of samples from the Smithsonian collections will be available soon.
|Large Eruptions of Zheltovsky||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).|
|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.|
