Parinacota is a massive
stratovolcano on the border of
Chile and
Bolivia. It is part of the
Nevados de Payachata group of volcanoes. The other major edifice in that group is the
Pleistocene peak of
Pomerape. Parinacota's last eruptive phase has been dated using the
helium surface exposure technique, which ties the eruption to 290AD ± 300 years.
One of the most dramatic eruptive events in the volcano's past was 8000 years ago, when a major collapse of the edifice produced 6km
3 debris avalanche. That avalanche blocked drainage patterns in some of the local area, creating
Lake Chungará.
