A volcano in central Indonesia has erupted, ejecting columns of thick ash as high as 24,606 feet into the sky.
Mount Soputan, on the northern part of Sulawesi island, erupted twice Sunday morning, said the national disaster agency's spokesman, Sutopo Purwo Nugroho.
He said that in anticipation of hot ash and lava sliding down the volcano's slopes, residents have been urged to avoid activities near the mountain.
Residents also were warned against the possible flowing of lava into rivers around the volcano, and urged to wear masks in case of ash rain.
Authorities kept the volcano's alert level at the second-highest level.
Soputan, which stands 5,853 feet tall, is one of Indonesia's more than 120 active volcanoes.
