A volcano on the Indonesian island of Sulawesi erupted on the morning of Wednesday, October 2.

The eruption comes just days after the 7.5-magnitude earthquake and tsunami struck Palu, killing more than 1,300 in one of the country's deadliest natural disasters.

This video, filmed at 12:05 am on Thursday, shows the glow of the lava against the night sky. The molten liquid slid 2,500 metres from the crater at the top of Mount Soputan, located in North Sulawesi.

The Center of National Disaster Management Agency (BNPB) announced that the eruption status had been elevated to Level 3.

Volcanic activity has increased in recent weeks leading up to the eruption, media reported, and locals have been advised to stay away from the vicinity to avoid contact with ash and potential lava flows.

It is not known if the earthquake and volcanic eruption were related.

Mount Soputan in Southeast Minahasa, North Sulawesi erupted again. Video filmed from the mountain slope which is only less than 300 meters on Wednesday at 11:00 p.m., shows lava slide to the northeast of 2,500 meters from the crater at the top of the mountain.

Head of the Data Information and Public Relations Center of National Disaster Management Agency (BNPB), Sutopo Purwo Nugroho, told the media that the eruption began on Wednesday morning made mountain status elevated to Level 3.

The government calls on people to avoid lava and heat clouds generated.

"From morning to night, Soputan erupted with 4,000-6,000 meters of volcanic ash and released lava and hot clouds leading west-southwest," Sutopo said.

The eruption of the Soputan volcano was the latest natural disaster to impact the Indonesian island of Sulawesi in recent weeks.
