Mount Nyiragongo is an active stratovolcano with an elevation of 3,470 metres in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about 20 km (12 mi) north of the town of Goma and Lake Kivu and just west of the border with Rwanda. Lava flows through down town of Goma and reaches Lake Kivu, only to 150 km depth. The most recent large eruption of Nyiragongo occurred in 2002 where 147 people killed. During this eruption lava flows moved through the city of Goma on the shores of Lake Kivu destroying 13% of the city and approximately 12,000 to 15,000 homes displaced hundreds of thousands of people.
