Andean Volcano Heats Up

March 31, 2003
A January 6, 2002 ASTER nighttime thermal infrared image of Chiliques volcano in Chile (left) shows a hot spot in the summit crater and several others along the upper flanks of the edifice, indicating new volcanic activity. Chiliques volcano was previously thought to be dormant. Rising to an elevation of 5778 m, Chiliques is a simple stratovolcano with a 500-m-diameter circular summit crater. This mountain is one of the most important high altitude ceremonial centers of the Incas. It is rarely visited due to its difficult accessibility.
