Purico Complex

The Purico Complex is an extensive volcanic landscape in the northern Andes comprising multiple stratovolcanoes, lava domes, and a large ignimbrite shield formation. The entire region spans across a vast area and sits at high elevation with harsh conditions year-round.

Volcanic activity in this area began roughly 1.3 million years ago and continues to shape the landscape today. The youngest structures formed less than 10,000 years ago, showing that volcanic processes remain ongoing.

The Purico Complex hosts several astronomical research facilities, including the Atacama Large Millimeter Array and Atacama Cosmology Telescope, contributing to space exploration.

The location sits at high elevation in a region with very harsh weather conditions, so good preparation for cold and low humidity is necessary. Visitors should keep in mind that the remote setting and rough climate require special equipment and planning.

Along the southeastern edges sits a crater from which volcanic gases continuously rise and alter the ground surface. This natural gas release is a visible sign of ongoing volcanic activity beneath the earth.
