Authorities and witnesses in Indonesia on Monday, 10 August, reported a giant ash cloud spanning 5 km into the sky, as a volcano erupted from Mount Sinabung a second time since Saturday, 8 August, on the island of Sumatra, according to Reuters.
The eruption came with a thunderous noise, and turned the sky dark, according to testimonies of eyewitnesses. The ash reportedly rose from the peak of the 2,460-metre (8,071-ft) mountain in Karo, North Sumatra.
Authorities have warned residents and tourists about possible lava flow, reported Reuters.
Indonesia’s volcanology agency has advised residents to stay outside of a 3 km radius of the volcano and to wear masks to minimise the effects of falling volcanic ash, the report said.
No casualties, however, have been reported. A spokeswoman for the civil aviation authority also told Reuters that flights are still operational in the region.
According to Reuters, Mount Sinabung has erupted after a year of remaining dormant. 2010 was the last time it erupted after being inactive for centuries.
Indonesia is reported to be one of the world’s most volcanically active countries.
