Indonesia has raised the alert level at one of its most active volcanos to the highest after it repeatedly sent hot clouds of gas down its slopes.
Volcanology hazard mitigation chief Surono says authorities have been ordered to evacuate people living along Mount Karangetang's slopes.
He says the 5,853-foot (1,784-meter) mountain on Siau, part of the Sulawesi island chain, spewed hot clouds of gas at least seven times Friday. There were no reports of injuries or damage.
It last erupted in August, killing four people.
Indonesia, the world's largest archipelago, lies on the Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin that is prone to earthquakes and volcanic eruptions.
