Only Puyehue and Cordón Caulle have erupted during the Holocene, and until 2011 only Cordón Caulle had recorded historical eruptions. In the interval between 7,000 and 5,000 years ago Puyehue had rhyolitic eruptions that produced lava domes. The lava domes were later destroyed after a sequence of strong eruptions that were part of an explosive eruptive cycle. These last eruptions were likely of phreatomagmatic and sub-plinian type and occurred around 1,100 years ago (~850 CE).
