Geological Summary

Vilyuchik, also known as Viliuchinsky or Uilyuchinsky, is a steep-sided Pleistocene-to-Holocene stratovolcano that forms a prominent landmark south of Avachinsky Bay. Deep erosional gullies dissect the flanks of the 2173-m-high volcano. Lava domes and young basaltic cinder cones were constructed at its base. Most of the growth of the volcano took place during the late Pleistocene. The last significant eruption took place from the summit crater about 10,000 years ago, producing a moderate airfall deposit and a lava flow. Landslides and rock avalanches from the steep-sided volcano have affected habited areas.

Steam plumes rise from geothermal prospects drilled during the late 1970's on the NE flank of Mutnovsky volcano. The wells yielded a steam-gas mixture from depths of 60-1200 m. The steep-sided Vilyuchik stratovolcano appears in the background to the NE.

An eruption plume from Gorely volcano drifts to the north across Avachinsky Bay in this 1980 view from Petropavlovsk, Kamchatka's largest city. Explosive activity began in June 1980, and intermittent explosions took place until July 1981. A strong eruption on July 31 produced an eruption plume that rose up to 5.5-km altitude, and a pyroclastic flow took place on December 3, 1980. The sharp-topped peak to the left of the eruption plume is Vilyuchik volcano.

Vilyuchik, also known as Uilyuchinsky, is a steep-sided Holocene stratovolcano that forms a prominent landmark south of Avachinsky Bay. It is seen here from the south, between Mutnovsky and Gorely volcanoes. Deep erosional gulleys dissect the flanks of the 2173-m-high volcano. Lava domes and young basaltic cinder cones were constructed at its base. It last erupted during the first half of the Holocene.

Clouds fill one of the snow-mantled summit craters of the Mutnovsky volcano complex, one of the most active volcanoes of southern Kamchatka. Koryaksky (left) and Avachinsky (right) volcanoes rise in the distance across cloud-covered Avachinsky bay.

Vilyuchik, one of several volcanoes surrounding Avachinsky bay, is the most prominent peak visible across the bay to the south from Petropavlovsk. Weather clouds drift to the east from the summit of the 2173-m-high stratovolcano in this mid-1980's view from Kamchatka's largest city. No eruptions have occurred from Vilyuchik since the early Holocene.

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.
