Calbuco, which erupted without warning on Wednesday, was still puffing out ash and smoke on Friday, leading airlines to cancel flights from Argentine capital Buenos Aires, some 1,400 kilometers east. Calbuco, considered one of the most dangerous along Chile's chain of around 500 active volcanoes, erupted twice in 24 hours on Wednesday and Thursday.
