Medan: Indonesia’s Mount Sinabung, a volcano erupted Monday, belching a massive column of ash and smoke 5,000 metres (16,400 feet) into the air and plunging local communities into darkness with a thick layer of debris.
The volcano on Sumatra island has been rumbling since 2010 and saw a deadly eruption in 2016.
Activity had picked up in recent days, including a pair of smaller eruptions at the weekend.
There were no reports of injuries or deaths from Monday morning’s blast, but authorities warned of possible lava flows and more eruptions.
“This is an alert for all of us to avoid red-zone areas near Sinabung,” said Armen Putera, a local official with Indonesia’s Volcanology and Geological Hazard Mitigation Centre.
However, the crater’s alert status remained at its second-highest level.
