Calbuco (Southern Chile and Argentina): A major explosive eruption started at the volcano yesterday afternoon (20:45 GMT). VAAC Buenos Aires reported an ash plume to 30,000 ft (10 km) altitude.
The eruption started at 18:05 local time and came with little warning signs apparently. Residents in a radius of 20 km around the volcano are being evacuated. As the ash plume quickly drifted northeast towards Argentinia’s Bariloche region, the Bariloche airport was closed.
According to Sernageomin, the eruption stopped already a few hours after. Aviation color code was raised to red as a warning to aircraft to avoid the area.
