2010 eruption At dawn on 2 January 2010 Nyamuragira began spewing out lava flows. There are no settlements close to the volcano, but wildlife officials feared that the eruption may threaten the
chimpanzees in the area. Another danger was that the lava could have flowed into the southern sector of
Virunga National Park, where there are settlements and villages. Extensive lava flows from the 2010 eruption can be seen on satellite photographs reaching south-west to Lake Kivu, about north-west and north-north-east.
2011 eruption The volcano erupted again on 5 November 2011. That eruption produced a high column of lava, and it is said to have been its largest eruption in 100 years.
2014 lava lake In 2014, a new lava lake appeared at the volcano for the first time in 75 years. The previous lava lake at the volcano was emptied in the 1938 lava flow. The formation of the new lake occurred between June and August 2014. It reached a depth of . The eruption did not affect the communities in the area but left a lot of ash and air pollution. Sulfate aerosols formed by volcanic sulfur dioxide from the eruptions were observed as far away as over the central Amazon rain forest in South America. By 2018, the lava lake had hardened and the activity appeared to have stopped. Eruptive activity continues during 2021 at the summit caldera.
2021 lava lake In 2021, a lava lake appeared at the volcano based on a June 11 satellite image.
2024 caldera overflow On July 26, 2024, lava began to overflow the northern caldera rim and flowed towards the northwest. This was accompanied by a large increase in effusive lava output. The flow advanced 5km in the first day.
2026 eruption On January 21, 2026, it was reported that an ongoing eruption was taking place at Nyamulagira. Incandescence was observed on the caldera floor and active lava flow up to 8 km from the crater rim. With reports from January 19, 2026, of lava flows extending as far as 10 km. == Etymology ==
