Mount Nyiragongo 2002 eruption case study
Case Study - Mt Nyiragongo Flashcards by Leah Dann | Brainscape
January 17 , JPEG. Mount Nyiragongo, located in the Democratic Republic of the Congo, erupted today January 17, , ejecting a large cloud of smoke and ash high into the sky and spewing lava down three sides of the volcano. According to news reports, one river of lava is headed straight toward Goma, where international aid teams are evacuating residents. Already, the lava flows have burned through large swaths of the surrounding jungle and have destroyed dozens of homes. The plume appears to be higher than the immediately adjacent clouds and so it is colder in temperature, making it easy for MODIS to distinguish the volcanic plume from the clouds by using image bands sensitive to thermal radiation. Nyiragongo eruptions are extremely hazardous because the lava tends to be very fluid and travels down the slopes of the volcano quickly.
Homes, schools, churches and businesses were ruined. The aid response, both by the UN and NGOs, focused on this loss of shelter, and defined entitlement to assistance according to its loss. What they needed was not commodities but cash. As aid responses go, Goma was not badly served.
Mount Nyiragongo is an active stratovolcano with an elevation of 3, m 11, ft  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. The main crater is about two kilometres 1 mi wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls — one at about 3, m 10, ft and a lower one at about 2, m 9, ft. Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history.
