What is the eruption frequency of mount Nyiragongo?

Mount Nyiragongo, located in the Democratic Republic of the Congo, has a history of frequent eruptions, with significant activity occurring approximately every 2 to 3 years on average. Its most notable eruptions occurred in 1977, 1982, and 2002, with the latter causing substantial damage to the nearby city of Goma. The volcano is characterized by its persistent lava lake, which contributes to its eruptive activity. Scientists closely monitor Nyiragongo due to its potential threat to surrounding communities.
