Puyehue Volcano is flat-topped volcano located in the Andes, on the border of Osorno Province and Ranco Province, southern Chile. It is surrounded by a volcanic sand plateau, with fumaroles and hot springs. The shallow summit caldera is ca 2 km wide and usually filled with snow. The name comes from Mapudungun language: puye = a creek fish, hue = place.
No historical eruptions are known from Puyehue, and eruptions in 1921-22 and 1960 listed in some sources actually occurred at Cordon Caulle volcano located to the northwest.
