Geological Summary

The Bliznetsy ("Twins") lava flows occupy a low-lying area east of the Sredinny Range and north of the Eastern Volcanic Zone volcanoes. The young flows lie south of the Ozernaya River about 80 km north of historically active Shiveluch volcano. Effusion of about 0.5 cu km of lava forming the Bliznetsy flows about 3000 years ago was preceded by weak phreatomagmatic eruptions. The unusual location of this recently studied young volcanic vent lies north of the margin of the subducting Pacific Plate.

Photo Gallery

The grayish area to the left of the clouds near the center of the NASA Landsat image (with north to the top) is the Bliznetsy ("Twins") lava flows. These flows were erupted about 3000 years ago in a low-lying area east of the Sredinny Range and south of the Ozernaya River, which is visible cutting diagonally across the upper right part of the image. The unusual location of this recently studied young volcanic vent lies north of the margin of the subducting Pacific Plate.

Two closely spaced vents visible near the center of this photo produced the Bliznetsy ("Twins") lava flows. Prominent flow levees are visible on the flows, which were dated at about 3000 years ago. Emplacement of the ca. 0.15 cu km lava field was preceded by weak phreatomagmatic eruptions.

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.
