As reported last week, on June 4, Southern Chile’s Cordón Caulle on Puyehue Volcano’s slopes erupted for the first time in 51 years. Across the entire Southern Hemisphere, the eruption has been causing travel nightmares not only for common journeyers, but also for U.N. Secretary General Ban Ki-Moon, who is on a regional tour. He had to bus to Buenos Aires and boat to Uruguay.
This past week, flights were canceled in Chile and Patagonian Argentina, as well as southern Brazil. On Monday another column of ash, shooting eight kilometers (5 mi) into the atmosphere, forced the closures of airports across the Southern Cone, from Santiago to Buenos Aires to Montevideo.
But South America isn’t the only place being affected by Puyehue-Cordón Caulle’s fallout. When winds shifted to the West over the weekend, the ash forced Qantas and other airlines to cancel flights in New Zealand and Australia.
Both Chile and Argentina have declared agricultural emergencies in their Lake and Patagonia regions. Lava flows have oozed down the Nilahue River valley. Over five million salmon were relocated when rising river temperatures caused fishkills.
Friday, rain and ash from the eruption caused an avalanche near the (closed) Cardenal Samoré border crossing road, which remains closed. To handle border traffic, the Chilean government has increased the number of ferries on Lago Pirehueico at the Hua Hum pass and has reopened Paso Pino Hinchado. Snows may force the re-closure of these crossings.
Chile’s Emergency Management Agency (Onemi) maintains a red alert for the Lago Ranco and Puyehue areas. Travelers are advised to watch the news for further developments.
