Flights disrupted as resurgent volcano spews more ash

Ash from Chile's spewing Calbuco volcano threatened on Saturday to make travel miserable as it triggered the cancellation of domestic and international flights in several cities.

A sleeping giant for more than 50 years, the volcano sprang to life in spectacular bursts of ash and lava on Wednesday and Thursday, forcing 6,500 people living nearby to evacuate and blanketing southern Chile in suffocating volcanic debris.

The mountain coughed out more fire and ash on Saturday, with an ash cloud drifting eastward over Patagonia and Argentina, reaching Buenos Aires 2,000 km away. Some airlines there canceled flights to and from the US and Europe.
