SANTIAGO (Reuters) - Chilean volcano Calbuco, which erupted without warning on Wednesday, is still puffing out ash and smoke on Friday, prompting new evacuations and leading airlines to cancel flights to Argentine capital Buenos Aires, some 1,400 kilometers east.
Calbuco, considered one of the most dangerous along Chile's chain of around 2,000 volcanoes, erupted twice in 24 hours on Wednesday and Thursday, sending up a spectacular 17 kilometer-high (11 miles) cloud and coating nearby towns in a thick layer of grey ash.
