CASE STUDY MT NYIRAGONGO

Watch this video clip about Mount Nyiragongo, Democratic Republic of Congo – it also makes a mini tourism case study. Forecasts and warnings are not likely to be acted upon by the population in the present political and humanitarian crisis. The centre of the outbreak was probably Goma. By 31 July, bloody diarrhoea S. Evacuation is nearly impossible as the Constructive margin in LEDCvolcanic ash prevents jets from taking off andthe runway is covered in a lava flow. Episodic lava-lake filling at Nyiragongo began on 23 June, the first such activity since when the lake first refilled after the eruption.

As many as , persons left, whilst a substantial number of people stayed behind in the area of the town between the lava flows and also in the western part of the city. These scenarios are also good reasons for not returning to the city after an eruption until the activity has clearly declined. Cholera risk in Goma. Close-up view of fresh Nyiragongo lava. Both the main supply pumping stations for the city, Lac Kivu and Turquoise, were out of action because the power supplies had also been disrupted by the eruption.

There are three principal volcano scenarios presented in sstudy draft plan that will need to be expanded upon in more detail as part of the Risk Assessment meeting.

Societal risk assessment and planning. The water network across the city was broken by both lava flows Fig.

The latter flows were much less hazardous to life, as they could be easily avoided, xase were more destructive Fig. It also caused methane gas http: The last event triggered fumarolic activity that was observed by local inhabitants.

Lava covered 13 percent of the city, or approximately 1. An unknown, but probably important, number of the diarrhoeal cases were cholera. The high death rate, which was almost entirely attributable to diarrhoeal disease, was unprecedented for refugee populations up to that time. However, the low mortality might make people underestimate the volcanic hazard in the future with consequently higher loss of life.

About 30, people stayed in the west part of the city during the eruption, and this area is not on the network. Steady degassing related to volcanic activity underneath the ground produces abundant CO 2 — the gas accumulates in topographic low spots because it is denser than air, and incautious people and animals can lose their lives quickly from a mazuku.

In particular, a huge school rebuilding programme generated budgets, employment and an explosion of small workshops making desks and chairs.

A service provided by UN OCHA ReliefWeb has been the leading online source for reliable and timely humanitarian information on global crises and disasters since Nyamuragira began erupting after a period of increasing seismicity underneath the volcano. Cholera epidemic, Julyand lessons learned from the mass movement of refugees in November Both eruptions were observed in satellite images. In this scenario, loss of life, property destruction, and displacement of approximatelypeople the populations of Goma and Gisenyi would likely result.

The acute impact of the volcanic crisis on the humanitarian situation has been small, as far as we can tell a “blip” according to one NGO official.

Nyiragongo In a major eruption from Mt Key Terms: We have shown above that political vulnerability is a main threat, with consequences for the population in affecting their responses to warnings from scientists on impending volcanic activity.

In the villages people can walk many kilometres a day to fetch water from water supply points standing pipes, bladders and trucks and Lake Kivu maximum distance between the lake and farthest dwellings is about 15 km. The most obvious difference between the two lava flows is that the western one had cooled much more than the main one by the time it reached Goma.

Education of the public and expatriate staff on volcanic hazards is urgently needed. BBC News – Goma resilient despite devastation. The scientific monitoring and evaluation work hyiragongo all be useless unless the lines of communication between the GVO scientists, foreign scientists and the appropriate officials, plus the local people, are all in place, and a satisfactory method of warning the people exists in the event of an impending future eruption.

Global change Unit 1: The areas where displaced people were living required new distribution systems.

The eruption should therefore have a significant effect in aggravating poverty in some social strata, at least. One very dramatic exception to this general rule is Nyiragongo, an active volcano located in the Western Rift within the Virunga Volcanic Province. Emergency planning for a major eruption of Nyiragongo presents several unique challenges. Numbers Affected as of February Total Affected: There is an urgent need to ensure the adequate monitoring of the volcano and to develop contingency planning for a future eruption.

Human development and diversity 5. These continued on a nyiargongo basis for about a week, and acted as a deterrent to some people returning to the city. Yet aid workers persisted in treating people like children who could not be trusted with their pocket money.

A city has not been devastated by lava flows before and the impacts of the two flows in January need to be carefully considered for future emergency planning.
