Geological Summary

Symmetrical Prevo Peak, also known as Simushiru-Fuji for its resemblance to Japan's noted volcano, is capped by a 450 x 600 m wide summit crater. A nested inner cone whose rim approaches the height of portions of the outer cone is itself cut by a deep, 350-m-wide crater with a small lake on its floor. Young-looking lava flows reach both coasts of central Simushir Island, and those on the south flank (Pacific Ocean side) have a particularly youthful appearance. Two small pyroclastic cones on the western flank have produced lava flows that reach to or near the Sea of Okhotsk. Only two eruptions are known from Prevo Peak in historical time. The largest of these, during the 1760s, produced pyroclastic flows that destroyed all vegetation at the foot of the volcano. Weak explosive activity occurred during the most recent eruption, which took place during the first half of the 19th century.

The dramatic symmetrical cone of Prevo Peak in central Simishir Island is seen in this Space Shuttle image (with north to the lower left). The conical volcano, also known as Simushiru-Fuji for its resemblance to Japan's noted volcano, is capped by a 450 x 600 m wide summit crater. Young-looking lava flows reach both coasts of central Simushir Island. Only two eruptions are known from Prevo Peak in historical time. The flanks of the Pleistocene Ikanmikot volcano appear at the far right.

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.
