Geological Summary

The 4-km-wide, glacier-filled Sollipulli caldera lies to the east of the Pleistocene Nevados de Sollipulli complex. Major silicic pyroclastic rocks associated with caldera formation have not been found, and the caldera may have a non-explosive origin. Post-caldera eruptions have been focused along the caldera walls and have increased its height. A series of dacitic lava domes lines the eastern and southern caldera rims. The 1-km-wide Alpehué crater, which cuts the SW rim, was the source of a large plinian eruption 2900 years before present (BP). Explosion craters and scoria cones are found on the outer flanks of the caldera. Two north-flank cones produced lava flows during the latest documented activity about 700 years BP (Naranjo et al., 1993). This low-profile volcano is less prominent than its neighbors Llaima and Villarrica, but its explosive history makes it a potentially hazardous volcanic center.

Ice-filled Sollipulli caldera forms a bullseye at the center of this NASA Space Shuttle image with north to the upper right. The tip of Lake Caburgua is at the left, and Laguna Aluminé at the lower right. The 4-km-wide caldera may have a non-explosive origin, but post-caldera eruptions formed a series of dacitic lava domes along the caldera rim, and the 1-km-wide Alpehué crater, which cuts the SW rim, was the source of a large plinian eruption 2900 years ago. The volcano was active as recently as about 700 years ago.

The broad profile of the snow-covered Sollipulli massif lies on the horizon to the NE as seen from the upper slopes of Villarrica volcano. A 4-km-wide caldera with post-caldera lava domes on its rim lies on the eastern side of the Nevados de Sollipulli volcanic chain. The rounded hills in the middle distance are pyroclastic cones of the Caburgua-Huelemolle volcano group; lava flows from these cones dammed drainages, forming Laguna Caburgua, visible at the upper left.

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.
