Geological Summary

The Udokan Plateau volcanic field occupies a broad area about 400 km ENE of the northern tip of Lake Baikal. Quaternary volcanism here represents the latest manifestation of activity dating back to the Miocene covering an area of 3000 sq km at the eastern margin of the Baikal Rift System. Late-Pleistocene to Holocene volcanic centers are concentrated along three major lineaments, and many eruptions were localized along fissures trending NW-SE and NE-SW. Dated Holocene volcanic centers are located on a 20-km-long line at the SW side of the volcanic field, but Holocene cinder cones also occur in the NE Udokan Plateau. Seismic activity has been recorded at depths of 15 to 20 km beneath some of the cones. The Udokan volcanic field is dominated by basaltic cinder cones, but basal trachytic ignimbrites are also overlain by lava domes and flows, and trachytic maars were formed during the final stages of activity. The latest dated eruption took place at Chepe volcano about 2200 years ago.

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.
