Indonesia's volcanology agency raised the alert level of the volcano to the highest level on Thursday, after Ibu erupted multiple times earlier this month.
Ibu's activities follow a series of eruptions of different volcanoes in Indonesia, which sits on the Pacific "Ring of Fire" and has 127 active volcanoes.
Flash floods and cold lava flow from Mount Marapi, one of the most active in West Sumatra province, covered several nearby districts following torrential rain on May 11, killing more than 60 people.
In recent weeks, North Sulawesi's Ruang volcano has also erupted, spewing incandescent lava. The eruption prompted authorities to evacuate more than 12,000 people on a nearby island.
