Geological Summary

Rucharuyama, with the small pyroclastic cones of Golets and Tornyi, is SW of Moyorodake (Medvezhia) volcano at one of the narrowest parts of Iturup Island, and formed during the late Pleistocene or early Holocene. A small lava flow from the 417-m-high Tornyi cone occupies a broad glacial cirque. The 442-m-high andesitic-dacitic Golets cone, constructed above the eroded remnants of the Pleistocene Parusnaya Mountain volcano, produced lava flows that reached the coast.

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

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.

Photo Gallery

The small pyroclastic cones of Golets and Tornyi are located near the center of the narrow Vetrovoi Isthmus in northern Iturup Island. At the upper left in this NASA Space Shuttle image (with north to the upper right) is Chirip volcano; at the lower right is Medvezhia volcano. The flat-floored caldera to the left of Medvezhia caldera is the Pleistocene Tsirk caldera. Golets and Tornyi pyroclastic cones formed during the late Pleistocene or early Holocene east (right) of the low-lying graben forming the narrow point of the peninsula.

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.
