Geological Summary

Lautaro is the northernmost of five volcanoes comprising the Australandean volcanic zone of the southernmost Chilean Andes and is the closest volcano to the Chile Triple Junction plate boundary. Volcanoes of the Australandean volcanic zone originated from subduction of the Antarctic plate beneath the South American plate. The Catalog of Active Volcanoes of the World synonyms for Lautaro (Cerro Pirámide, Chalten, and Chaltel) are actually synonyms of the dramatic Patagonian granitic peak of Cerro Fitz Roy (Moreno 1985, pers. comm.). Glacier-covered, 3607-m-high Lautaro volcano, the highest Chilean volcano below 40 degrees south, rises above the Southern Patagonian Ice Field. It has a crater just below its summit on the NW side, and a 1-km-wide crater is located on the NE flank. Ash deposits from eruptions of this dominantly dacitic volcano were visible on aerial photos taken during several occasions during the 20th century, and older ash layers form prominent markers on outflow glaciers of the Patagonian icecap.

The northern side of Lautaro volcano rises above a sea of clouds. A 300-km gap occurs between Cerro Hudson and Lautaro, the northernmost of five volcanoes comprising the australandean volcanic zone of the southernmost Chilean Andes. Glacier-covered, 3607-m-high Lautaro volcano, the highest Chilean volcano below 40 degrees south, has a crater just below its summit on the NW side, and a 1-km-wide crater is located on the NE flank.

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.
