Geological Summary

Little is known of this isolated volcano that was seen in eruption by Darwin in 1834, and an eruption was reported to have occurred in November 1835. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. A series of lakes flank the eastern side of the basaltic to basaltic-andesite structure. Eruptions in historical time were considered likely from these postglacial volcanoes (Moreno 1985, pers. comm.).

The dramatic summit spire of Volcán Corcovado is seen here in an aerial view from the south. Two of a string of lakes on its eastern side appear in the background. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. Eruptions were reported in historical time from these flank cones. Darwin observed activity from the Corcovado area in 1834, and an eruption was reported to have occurred in November 1835.

The dramatic summit spire of Corcovado volcano is seen in this telephoto view from the west from the town of Quellon on the island of Chiloe. The volcano rises across the Gulf of Corcovado, which lies beyond the ridge in the middle distance. The main edifice at Corcovado is likely Pleistocene in age, but historical eruptions have been reported, probably from Holocene cinder cones surrounding the volcano.

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.
