Signs of awakening despite recent dormancy

On 12 April 2002, NASA's Jet Propulsion Laboratory reported that new images taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (Aster) on NASA's Terra satellite showed signs of activity at Chiliques. This volcano was previously considered to be dormant; however, on 6 January, a nighttime thermal infrared image from Aster showed a hot spot in the summit crater, as well as several others along the upper flanks, indicating new volcanic activity (figure 1). Examination of an earlier nighttime thermal infrared image from 24 May 2000 showed no such hot spots.

Geological Summary

Volcán Chiliques is a structurally simple stratovolcano located immediately south of Laguna Lejía. The 5778-m-high summit contains a 500-m-wide crater. Several youthful lava flows, some of which are considered to be of possible Holocene age (de Silva, 2007 pers. comm.), descend its flanks. The largest of these extends 5 km to the NW. Older lava flows reach up to 10 km from the summit on the north flank. This volcano had previously been considered to be dormant; however, in 2002 a NASA nighttime thermal infrared satellite image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) showed low-level hot spots in the summit crater and upper flanks.

The Global Volcanism Program is not aware of any Holocene eruptions from Chiliques. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Chiliques page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Volcán Chiliques, the conical peak at the left, is a structurally simple stratovolcano located immediately south of Laguna Lejía. A 500-m-wide snow-capped crater truncates the summit and contains a small lake. The volcano was constructed over a base of dacitic lava domes and andesitic lava flows. Youthful lava flows radially descended from the summit as far as 5 km to the NW. The volcanic complex at the right is the Pleistocene Volcán Lejía, which was constructed within a 3.5-km-wide caldera.

An ASTER satellite image from NASA in November 2000 looks down onto the summit crater of Chilques volcano. Radial gullies descend the flank of the volcano. Nighttime thermal infrared images on April 12, 2002 revealed hot spots in the summit crater and along the upper flanks, marking the first observations of historical activity at the volcano.

Snow-capped Volcán Chiliques is a conical stratovolcano located NNE of Laguna Miscanti (foreground). The 5778-m-high summit of the volcano contains a 500-m-wide crater. Several youthful lava flows, some of which are considered to be of Holocene age descend its flanks. Chiliques had previously been considered to be dormant; however, in 2002 a NASA nighttime thermal infrared satellite image showed low-level hot spots in the summit crater and upper flanks.

The 5778-m-high summit of Chiliques contains a 500-m-wide crater, and some youthful lava flows may be of Holocene age. This volcano had previously been considered to be dormant; however, in 2002 a NASA nighttime thermal infrared ASTER satellite image showed low-level hot spots in the summit crater and upper flanks. Miscanti volcano is of probable late-Pleistocene age.

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.
