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.

Photo Gallery

Milne, the southernmost volcano on Simushir Island, lies immediately SE of Goriaschaia volcano (far left) in this Space Shuttle image (N is to the upper left). The walls of a 3-km-wide Pleistocene crater that opens towards the sea are visible in the lower half of the image. The small, mostly snow-free central cone near the crater headwall contains a lava dome that was constructed during postglacial time and forms the highest point on the island.

Goriaschaia Sopka dome and the Milne cone are shown here on the SW end of Simushir Island. Milne is the larger snow-capped peak and Goriaschaia Sopka is on the NW flank within a large open crater. The dome has produced lava flows that form the irregular shoreline to the N, some of which are visible in this NASA Space Shuttle image.

Milna is the southernmost volcano on Simushir island, shown in this August 2020 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 13 km across). There is a large scarp across the SE side of the island, opening towards the sea. Within the scarp is a lava dome that grew higher than the scarp walls, and on the NW flank is the Goriaschaia Sopka lava dome with lobate lava flows extending the coastline.

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.

MODVOLC Thermal Alerts

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.

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

Volcanic Hazard Maps

The IAVCEI Commission on Volcanic Hazards and Risk has a Volcanic Hazard Maps database designed to serve as a resource for hazard mappers (or other interested parties) to explore how common issues in hazard map development have been addressed at different volcanoes, in different countries, for different hazards, and for different intended audiences. In addition to the comprehensive, searchable Volcanic Hazard Maps Database, this website contains information about diversity of volcanic hazard maps, illustrated using examples from the database. This site is for educational purposes related to volcanic hazard maps. Hazard maps found on this website should not be used for emergency purposes. For the most recent, official hazard map for a particular volcano, please seek out the proper institutional authorities on the matter.

DECADE Data

The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the Mapping Gas Emissions (MaGa) Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO₂ to the atmosphere, but installing CO₂ monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.
