Geological Summary

Four groups of basaltic cinder cones lie east of Lago Villarrica and NE of Villarrica volcano. The northernmost and southernmost groups, the Volcanes de Caburgua and Volcán Huelemolle, respectively, lie along the major regional Liquine-Ofqui fault zone. Volcanes de Caburgua lies at the south end of Lago Caburgua and consists of six early Holocene basaltic cinder cones. Lava flows from these cones contributed to blockage of river drainages that formed the lake. The southernmost group, Volcán Huelemolle, consists of three early Holocene basaltic cinder cones between the Liucura and Pucón (or Minetué) rivers. The two other cone groups, Volcán Redondo and Pichares, lie to the east of Caburgua and Huelemolle. Stratigraphic evidence indicates that these basaltic cone groups were active between about 6000 and 8000 years ago.

Photo Gallery

Four groups of basaltic cinder cones lie along the major regional N-S-trending Liquine-Ofqui fault zone, which trends parallel to Lake Caburgua (top). The northernmost group of cones lies at the southern end of Lake Caburgua and was the source of lava flows that dammed drainages, forming the lake. The southernmost group, Huelemolle, is the rounded forested area between two rivers at the bottom-center. Two other cone groups lie to the east of Caburgua and Huelemolle. Lake Villarrica is at the lower left, and Colico Lake is at the upper left.

Forested Volcán Relicura, rising to the NW from near the Liucura Bridge, is part of four groups of basaltic cinder cones lying east of Lago Villarrica and NE of Villarrica volcano. The northernmost and southernmost groups, the Volcanes de Caburgua and Volcán Huelemolle, respectively, lie along the major regional Liquine-Ofqui fault zone. Lava flows from the half dozen cinder cones of the Volcanes de Caburgua blocked drainages, forming elongated Lago Caburgua.

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.
