Marapi volcano on Sumatra island, West Sumatra province of Indonesia spewed ash again, forcing 150 people to evacuate.
The eruption comes six weeks after the Marapi volcano erupted early last month, killing 23 people.
According to the Indonesian Geological Agency, the Marapi volcano in West Sumatra province erupted at least twice on January 14, sending ash columns up to 1,300 meters high, heading towards the southwest area of the volcano's peak.
Authorities have asked people living within a 4.5km radius of the crater to evacuate as lava could flow into rivers and valleys. In the event of ashfall, people should wear masks to protect against respiratory illnesses.
Last week, authorities raised the Marapi volcano's eruption alert to the second highest level after increased volcanic activity.
Standing at 2,891 metres above sea level, Marapi is the most active volcano on the island of Sumatra. Indonesia lies on the Pacific "Ring of Fire" and regularly experiences seismic activity and volcanic eruptions.
