Which volcano has the largest active lava lake in the world?

Nyiragongo is a highly active stratovolcano in the Virunga Mountains and is especially known for its fast-moving lava and persistent lava lake. The lava lake has changed size over time, but Nyiragongo has long been one of the most important examples of a continuously or repeatedly active lava lake. Its eruptions are dangerous because the lava is unusually fluid and can travel quickly into populated areas. The volcano erupted catastrophically in 1977 and again in 2002, causing severe destruction around Goma. Nyiragongo is a major volcanic hazard in central Africa.
