Geological Summary

Osorezan, on the Shimokita Peninsula in northernmost Honshu, contains a 5-km-wide caldera partly occupied by a shallow lake that drains through the N caldera wall. Dissected lava domes ring the caldera floor. The andesitic-to-dacitic volcano is largely Pleistocene in age, with activity dating back about 800,000 years. The last identified distal tephra deposit was erupted during the late Pleistocene. The only report of historical activity was in a Tohoku district travel document published in 1787, which stated that Yakeyama in Mutsu country (Osoreyama) had erupted. Older residents reported that large fires and clouds were sometimes seen from the summit, accounting for the volcano's local name, Yakeyama, or "Burning Mountain" (Murayama, 1987). Earthquake swarms have been documented during the second half of the 20th century, and magma bodies have been detected beneath the volcano.

The SE side of Osore-yama, on the Shimokita Peninsula in northernmost Honshu, rises above Mutsu Bay. Osore-yama contains a 3-km-wide caldera partly occupied by a shallow lake that drains through the north caldera wall. Dissected lava domes ring the caldera floor. The only report of historical activity at Osore-yama was in a Tohoku district travel document published in 1787, which stated that Yake-yama ("Burning Mountain") in Mutsu country (Osore-yama) had erupted.

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.
