According to Wikipedia: Puyehue and Cordón Caulle are two coalesced volcanic vents that form a major mountain massif in Puyehue National Park in the Andes of Ranco Province, Chile. In volcanology this group is known as the Puyehue-Cordón Caulle Volcanic Complex (PCCVC). Four different volcanoes constitute the volcanic group or complex, the Cordillera Nevada caldera, the Pliocene Mencheca volcano, Cordón Caulle fissure vents and the Puyehue stratovolcano.
Lightning bolts strike around the Puyehue-Cordon Caulle volcanic chain in the Patagonia region at sunrise June 5. The volcano dormant for decades erupted in south-central Chile on Saturday, belching ash over 6 miles into the sky, as winds fanned it toward neighboring Argentina, and prompting the government to evacuate several thousand residents, Chilean authorities said.

Puyehue volcano erupted for the first time in half a century on June 4, prompting evacuations for 3,500 people as it sent a cloud of ash that reached Argentina. The National Service of Geology and Mining said the explosion that sparked the eruption also produced a column of gas six miles high, hours after warning of strong seismic activity in the area.
