New Delhi: Two volcanoes erupted on Monday in Indonesia, prompting warnings for flights and evacuation preparations, officials said.
Mount Sinabung in North Sumatra province unleashed volcanic ash as high as 8,000 meters (26,250 feet), the highest of its eruptions in recent days, said government volcano expert Surono.
The 2,600-meter (8,530-foot)-high mountain has sporadically erupted since September after being dormant for three years.
Europe's tallest and most active volcano Mount Etna erupted on Saturday, spewing glowing lava into the air and sending a vast plume of smoke over the southern Italian island of Sicily.
