Geological Summary

Milna (or Mil'na) is the southernmost volcano on Simushir Island in the central Kuriles, and includes the Goriaschaia Sopka lava dome on the NW flank. The outer flanks of the steep-sided 1500-m-high volcano are dissected by deep gullies. A 3-km-wide caldera breached widely to the SE was formed during the Pleistocene and became a center of glaciation. A small central cone capped by an andesitic lava dome was constructed within the caldera during postglacial time and forms the highest point on Simushir Island. Lava flows from the cone descend 4-5 km to the sea. Goriaschaia Sopka, previously identified as a distinct volcano, is a historically active andesitic lava dome that grew just beyond what appears to be a NE-SW erosional scarp along the NW flank. Numerous fresh lava flows with prominent marginal levees extend from the dome, with some reaching the sea. It may have formed as recently as the late-19th century; dominantly mild-to-moderate explosive eruptions have occurred since 1842.

Milne volcano, the southernmost on Simushir Island, lies immediately SE of the somma of Goriaschaia volcano (far left) in this Space Shuttle image (with north to the upper left). The walls of a 3-km-wide Pleistocene caldera breached widely to the sea are prominent on the right side of the image. The small, mostly snow-free central cone near the caldera headwall is capped by a lava dome that was constructed within the caldera during postglacial time and forms the highest point on Simushir Island.

Two overlapping volcanoes anchor the SW end of Simushir Island, Goriaschaia Sopka and Milne. Goriaschaia Sopka (top) is a young, historically active lava dome that has been the source of youthful lava flows whose margins are visible on the volcano's flanks and form the irregular shoreline at the top of this NASA Space Shuttle image. The dome is located within a large horseshoe-shaped crater cutting the NW flank of the older Igla Mountain volcano. Milne is the large snow-capped stratovolcano immediately to the SE of Goriaschaia Sopka.

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.
