Geological Summary

Ruruidake is a late-Pleistocene andesitic-to-dacitic volcano NW of Tiatia volcano at the NW tip of Kunashir Island in the southern Kuriles. On the S flank is the Smirnov stratovolcano, a gently sloping 1189-m-high structure that in part retains a constructional form, but the southern side has been heavily eroded by glaciers, exposing its Tertiary basement. A wide glacial trough on the SE flank of Smirnov contains a pyroclastic cone at its head that fed a 4-km-long lava flow. Another pyroclastic cone is located at the base of the trough near the terminus of the lava flow. Two fresh-looking lava domes of Holocene age also lie within the glacial valley to the north.

The Global Volcanism Program is not aware of any Holocene eruptions from Ruruidake [Smirnov]. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ruruidake [Smirnov] 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 gently sloping volcanic massif on the left-center horizon, left of sharp-peaked Rurui volcano, is Smirnov volcano. These two volcanoes are located at the NW tip of Kunashir Island. Smirnov volcano has been extensively eroded by glaciers, but contains young pyroclastic flows and lava domes. The late-Pleistocene Rurui volcano has an active fumarole field on its western flank. The fresh crater in the foreground is the northern crater of the 1973 eruption of Tiatia volcano, SE of Smirnov and Rurui.

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.
