An Indonesia volcano, Mount Sinabung in North Sumatra province, erupted on Saturday; killing seven villagers and seriously injuring two . The volcano activity is potentially high, more eruptions are forecasted to happen.

According to news.com.au, the volcano spewed hot ashes and blazing lava three kilometres into the sky; stretching 4.5 kilometres westward into a river. It unleashed fast-moving clouds of volcanic gases and ashes into the village.

Nata Nail, an official at the local Disaster Management Agency, said that six bodies of villagers were found near the mountain. Another man died in the hospital on Sunday.

The victims are from the village of Gamber, in Simpang Empat subdistrict; they were working on their farms 2.5 miles away from the mountain, which is considered a red zone when it happens.

“This area should have been empty because nobody should be inside the red zone,” said National Disaster Management Agency spokesman Sutopo Purwo Nugroho in a report by Weather.

Rescue teams, personnel from disaster combating agencies, police and soldiers searched the area for more victims. They halted the search after no other victims were found.

All the dead bodies of victims were buried on Sunday.

Moreover, other villagers were prohibited from entering the village to collect their belongings. Roadblocks have been set up by the soldiers.

“It is not known exactly how many people were in Gamber village when the hot clouds descended,” said Nugroho in a report by The Guardian.

Sinabung sits in the Karo plateau of Karo Regency, North Sumatra, Indonesia. It had been asleep for four centuries before the eruption in August 2010. There were also some eruptions observed in September and November in 2013 and earlier in 2014. In 2015, the volcanic alert was high. Around 10,000 people were evacuated, due to suspected eruptions.

The volcano is susceptible to the seismic turbulence and is among more than 120 active volcanos in Indonesia.
