Event details

The Sinabung volcano on Indonesia's Sumatra Island erupted Saturday spewing ash and smoke 2,000 meters (6,600 feet) above its crater. The Center for Volcanology and Geological Hazar Mitigation (PVMBG) warned residents should not have any activity near the volcano, with official Muhammed Nurul Assori de Naman urging those in the Teran, Berastagi, Simpang, and Merdeka regions to wear masks to shield against ash rain. The volcano reactivated for the first time in four centuries in 2010. A total of 23 people were killed in 2014 and 2016 from eruptions.

Situation update

A rumbling volcano in western Indonesia has unleashed an avalanche of scorching clouds down its slopes. Authorities are closely monitoring Mount Sinabung on Sumatra, one of Indonesia’s main islands, after sensors picked up increasing activity in past weeks. The volcano in North Sumatra province has been shooting smoke and ash more than 3,280 feet high on Sunday morning, and hot ash clouds traveled southeast. There are no casualties. The 8,530-feet Sinabung was dormant for four centuries before exploding in 2010, killing two people. Another eruption in 2014 killed 17 people, while seven died in a 2016 eruption. The volcano, one of two currently erupting in Indonesia, has sporadically come to life since then. It’s among more than 120 active volcanoes in Indonesia.
An Indonesian volcano spewed a giant ash cloud 5 km (3.1 miles) into the sky on Monday in its second eruption in three days, emitting a thunderous noise and turning the sky dark, authorities and witnesses said. The eruption of Mount Sinabung on the island of Sumatra comes after more than a year of inactivity and was the second since Saturday, as authorities warned residents and tourists about possible lava flows. Dramatic footage of the morning eruption captured by residents showed a giant cloud of thick ash rising from the peak of the 2,460-metre (8,071-ft) mountain in Karo, North Sumatra. “The sound was like thunder, it lasted for less than 30 seconds,” resident Fachrur Rozi Pasi told Reuters by phone. Residents have been advised to stay outside of a 3 km radius of the volcano and to wear masks to minimise the effects of falling volcanic ash, the volcanology agency said in a statement. No casualties have been reported and a spokeswoman for the civil aviation authority said flights were still operating in the region. “The situation around Mount Sinabung is very dark now,” said Gilbert Sembiring, who was visiting a friend in Naman Teran Kampung when Sinabung erupted. “It was bigger than the eruption a couple of days ago.” Sinabung, located in one of the world’s most volcanically active countries, had been inactive for centuries before it erupted again in 2010.
Indonesia's Mount Sinabung erupted again Thursday with a string of blasts that sent plumes of ash two kilometers (1.2 miles) into the sky, triggering a flight warning and fears of lava flows. The activity marked at least the eighth time that the rumbling volcano on Sumatra island has erupted in less than a week, although there were no injures or major damage reported. Authorities issued a warning to planes flying near the volcano which last saw a deadly eruption in 2016. "There is potential for more eruptions and airlines are aked to be on alert," said National Disaster Mitigation Agency spokesman Raditya Jati. The crater's alert status remained at the second-highest level. Jati said authorities had marked a five-kilometer no-go-zone around Sinabung and warned of possible lava flows. "Locals are advised to wear face masks if they leave their homes to guard against the health effects of volcanic ash on health," he added. On Monday, Sinabung belched a tower of smoke and ash some five kilometers high, coating local communities in a thick layer of debris, after eruptions at the weekend. Sinabung roared back to life in 2010 for the first time in 400 years. After another period of inactivity, it erupted once more in 2013 and has remained highly active since.
After being inactive for more than a year, Mount Sinabung in Karo regency, North Sumatra erupted early on Saturday morning, spewing ash 2,000 meters into the air. The volcanic ash reached Berastagi, which is located around 30 kilometers from the volcano. Muhammad Nurul Asrori of the Sinabung observation post said the volcano began erupting at 1:58 a.m. and continued for one hour. He advised local residents and tourists to stay outside a 3-km radius from the mountain top. “We need to stay cautious because Mt. Sinabung’s status is still at level III, Siaga [Alert],” Nurul said. There were no casualties in the eruption, but several local residents living around the volcano were shocked by the event. The ash covered the residents’ plantation and killed crops. A villager of Naman Teran, Pelin Depari, said residents living 5 km from the volcano could hear the mountain rumbling, although they could not see the eruption directly because Sinabung was covered by fog. “It is traumatic because it has been a year since the last time Mt. Sinabung erupted,” said Pelin on Saturday. He added villagers were now cleaning their houses and fields of the volcanic ash. Karo Disaster Mitigation Agency (BPBD) acting chairman Natanael Perangin-angin said the last time Sinabung erupted was in June 2019. “We thought we were safe. I hope there won’t be another eruption.” He added that at least four districts were affected by the eruption, namely Naman Teran, Merdeka, Berastagi, and Dolat Rayat. Although the volcanic ash covered the districts, authorities said no residents had been displaced by the eruption, Natanael went on to say. Officials of the disaster agency, along with local military and police personnel, had distributed 1,500 masks and assisted locals in cleaning the volcanic ash. The local fire department dispatched five trucks to help the cleaning. The 2,460-meter Mt. Sinabung roared back to life in 2010 for the first time in 400 years. After another period of inactivity, it erupted once more in 2013 and has remained highly active since. Sixteen people died in one of Sinabung’s eruptions in 2014. Two years later, another eruption killed seven people. Apart from Mt. Sinabung, volcanic authorities have also placed Mt. Karangetang in North Sulawesi at alert level Siaga. Indonesia is home to about 130 volcanoes because of its position on the Ring of Fire, a belt of tectonic plate boundaries circling the Pacific Ocean where frequent seismic activity occurs.
Indonesian authorities on Saturday issued a flight alert following the eruption of the Sinabung volcano in North Sumatra province. The National Volcanology Agency said that the 2,475-meter high volcano located in Karo district spewed a 2-km high column of volcanic ash, reports Xinhua news agency. Planes have been prohibited to fly in the airspace above the hot cloud areas, as a volcano observation notice for aviation with the orange level was in effect. The potential of the further eruption remains along with the release of hot clouds. Heavy rains of volcanic ash are threatening the areas located in the slope of the volcano, and the volcanic materials may be spread further by the wind to regions located out of the slope. No-go zones have been declared in the radius of three km from the crater, and four km for the areas situated from the east to the north of the crater, as well as five km for the areas located from the south to the east of the crater. Sixteen people were killed and thousands of others were forced to flee home when Mount Sinabung erupted in 2014. Sinabung is one of the 129 active volcanoes in Indonesia, a vast-archipelagic nation home to over 17,500 islands.
