Geological Summary

A group of late-Pleistocene to Holocene cinder cones lies on the Teslin Plateau in NW-most British Columbia, east of Atlin Lake. The largest volcanic feature is 1880-m-high Ruby Mountain (named for the brilliantly colored tephra deposits at its summit and flanks), which has been partially dissected by Pleistocene and post-Wisconsin glaciation. Two basaltic cinder cones at the heads of Cracker and Volcanic Creeks lie within glacially dissected U-shaped valleys and were considered to be of postglacial age (Edwards et al., 1996). Placer miners working in the region at the end of the 19th century reported an eruption from the Ruby Mountain area about 80 km south of Gladys Lake (Hickson et al., 1994; Edwards et al., 1996) during which ashfall was reported for several days and the miners were able to work at nights due to incandescent glow from the eruption. No field evidence has been found, however, for a volcanic cone or lava flow in the Atlin area young enough to have been the product of an historical eruption, and the report is considered uncertain.

Cracker Creek cone (center), the small vegetated hill seen here from the west, is the youngest feature of the Atlin volcanic field on the Teslin Plateau in NW British Columbia. The small cinder cone lies at the head of Cracker Creek, immediately east of Ruby Mountain volcano, and may have been the source of a large lava flow that partly filled Ruby Creek. The lower west side of the cone appears to be partly covered by glacial till, suggesting that the cone is older than the most recent glacial advances down Ruby Creek.

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.
