A warning notice was issued to airlines after a rumbling volcano in Indonesia shot billowing columns of ash more than 16,000 feet into the atmosphere.
Mount Sinabung on the island of Sumatra erupted on Monday morning, sending hot clouds down its slopes.
The National Disaster Mitigation Agency said there were no fatalities or injuries.
The volcano, one of three currently erupting in Indonesia, was dormant for four centuries before exploding in 2010, killing two people.

Disaster agency spokesman Sutopo Purwo Nugroho said hot ash clouds travelled as far as 16,000 feet southwards.
The regional volcanic ash advisory centre in Darwin, Australia, issued a "red notice" to airlines.
Some 30,000 people have been forced to leave homes around the mountain in the past few years.
