Geological Summary

Tacora, the northernmost volcano of Chile, is a twin volcano with Chupiquiña to the north and lies near the Peruvian border. The andesitic volcano overlies a flat-lying platform of ignimbrites at about 4200 m elevation forming the Arica Altiplano. The roughly conical edifice is covered by glaciers down to about 5500 m elevation, and an explosion crater lies on the NW side 300 m below the summit. Solfataric and fumarolic activity has been reported on the east side (Catalog of Active Volcanoes of the World), but Moreno (1985 pers. comm.) indicated there may not have been Holocene eruptions. Young lava flows on the S flank appear to overlie glacial valleys (de Silva 2007, pers. comm.). Hantke (1939b) cited a report of eruptions in 1930 and 1937 that are not listed in other sources. Numerous sulfur mines occupy the saddle between Tacora and Chupiquiña, and hot springs are located on the eastern side of Tacora.

Towering 5980-m-high Tacora, the northernmost volcano of Chile, lies near the border with Perú and is a twin volcano with Chupiquina. Tacora is seen here from the SE. Although there have been uncertain reports of historical eruptions, and solfataric and fumarolic activity has been reported on the east side, Holocene eruptions from Tacora have not been documented.

Tacora, the northernmost volcano of Chile, rises to the NW above the steep-walled Allane valley. The 5980-m-high Tacora lies near the border with Perú and is a twin volcano with Chupiquina, hidden behind Tacora in this view. Although there have been uncertain reports of historical eruptions, and solfataric and fumarolic activity has been reported on the east side, Holocene eruptions have not been documented. The Arica to La Paz railway transects the plateau on the northern side of the Allane valley.

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.
