Hundreds of villagers have been evacuated after a volcano erupted in eastern part of Indonesia, officials said here Tuesday.

Mount Karangetan on Siau Island, of North Sulawesi province has been on top alert status since Sunday, as the volcano has formed a crater on its side and spewed black ash carrying hot materials up to two kilometers, head of Indonesian Volcanology Agency Surono who goes with single name said.

"The mount has erupted and formed craters at its side and spew black ash carrying hot material, which is very dangerous," he told Xinhua.

"We have closed the area for any activities up to 3 kilometers," he said.
