After a series of small earthquakes, southern Chile’s Volcán Puyehue-Cordón Caulle re-awoke last Saturday (June 4) with a 10,000-meter (32,600-ft) high column of smoke and ash. The eruptions are occurring on Puyehue’s (2,236 meters / 7,267 feet) slopes. The present activity is northeast of the vents triggered by the 1960 earthquake, which was the largest in modern history.
Over 3,500 people have been evacuated from the Puyehue region and Lago Ranco. Parque Nacional Puyehue has been declared a red zone, and is closed from the customs complex to Hotel Termas Puyehue. Paso Cardenal Samoré, the region’s major border crossing between Chile and Argentina, is closed.
Early Monday winds shifted to the northwest, blowing ash over Osorno. The Oficina Nacional de Emergencia (Onemi) director of the Los Lagos Region, Andrés Ibaceta, stressed that as spectacular as the eruption is, this is an emergency situation. Tourists should keep away from the Cordón Caulle area.
Travelers are advised to watch the news for further developments. To keep up on Volcán Puyehue-Cordón Caulle’s activity, check Chile’s Servicio Nacional de Geología y Minería (Sernageomin) website. Erik Klemetti’s Big Think has a good explanation (in English) of the eruption. The BBC and El Mercurio have spectacular photo slideshows.
