Massive Eruption Covered Large Regions in Ash and Pumice

The Eruption Aftermath

The volcanic ash blanketed the Andes and Patagonia regions with a thick blanket of ash and pumice before reaching the Argentine Atlantic Coast. The cities affected by the ash included Puerto Madryn and Trelew, in Chubut, as well as the towns of San Carlos de Bariloche and Villa La Angostura, a report said.

“Local authorities assured there is a layer of ash that’s at least 30 centimetres high over the National Route 40 in the area close to Bariloche and Neuquén. Border patrol has discouraged residents from driving in the area.”
