NYIRAGONGO VOLCANO CASE STUDY

The humanitarian and political situation also has a close bearing on the resources that can be brought to volcano monitoring and the forecasting of eruptive activity, as well as the responses of the population to the communication of volcanic risk and warnings to evacuate in a crisis. Other dangerous gases that needed to be excluded include methane, hydrogen sulphide and carbon monoxide. The lake was pH 8 the organisms can only multiply in alkaline media, but are killed in fresh water. The centre of the outbreak was probably Goma. The risk of enteric disease was increased further by the destruction of housing by the flows and the resultant overcrowding. The lessons that need to be considered in volcanic risk management for the present population of the Goma area include the following:. This approach includes the careful siting of human settlements and key infrastructure, such as hospitals and other buildings of importance, overhead power supplies and sub-stations, the water pumping stations and the water distribution networks, stores of emergency food and other essential supplies, etc.

Other dangerous gases that needed to be excluded include methane, hydrogen sulphide and carbon monoxide. Most of the increased attendances were children, with a disproportionate increase in the number of patients with respiratory diseases between 23 January and 5 February peaked January , declining to a more normal level by mid-February. ReliefWeb has been the leading online source for reliable and timely humanitarian information on global crises and disasters since The lake was pH 8 the organisms can only multiply in alkaline media, but are killed in fresh water. Either of these events could lead to catastrophic loss of life. Goma does not contain high-rise or densely packed buildings, so fires set off by the lava flows did not spread much further than the lava flow edge. The findings could be updated as new information on the volcano was obtained from new scientific work and in the light of developments in volcanic activity.

What we can conclude at this stage is that vulnerability amplifies the danger to the population of Goma in two main ways.

Stuudy is sufficient scope for a full-time post based in Goma, and the development of project proposals for work on the health aspects of the crisis:.

The two mass movements of refugees, in andwere amongst the most dramatic population movements in history. The name of Goma will be forever linked to the Rwandan genocide of and the huge humanitarian crisis that was provoked when the refugees fled for their lives across the border with Zaire now Congo and established camps near the city – at Mugunga the largestKatale, Kibumba and Munigi. Who could ever tell that someone had gone round twice, or that a nyiragkngo was represented at three different distribution points?

These had not been possible to repair because of a shortage of money. In view of the scientific uncertainties involved any risk assessment must be probabilistic, taking into account a range of possible scenarios and their casualty consequences.

The roads would be inadequate for large loads of traffic. We were reliably informed that the mood of the population changed from expectancy to rapid exodus when lava vents were seen to develop within the city in advance of the main lava flow this observation is a critical one, and requires further confirmation.

This reliance is unchanged today and the prevention of enteric disease outbreaks in a future eruption has to be a leading priority for the health sector, relief agencies and NGO’s. The epidemiological surveillance programme showed a large increase in total attendances at the two hospitals and 18 functioning primary health care centres after nyiragongoo eruption Fig.

According to scientists, the two main hazards of immediate concern in a future eruption of Nyiragongo are: Cost-recovery in the health sector: This is the first time that a lava flow has impacted on a city and made such a large number of people homeless.

The loss of the commercial centre and housing has meant a loss of jobs and disruption of the economy. The recent volcanic activity most related to the present crisis occurred in when Rwandan refugees settled in camps on the slopes of both volcanoes.

Lower down in the Munigi area, the eruption appears to have been more gas driven. Nyiragongo In a major eruption from Mt Key Terms: A well co-ordinated relief programme was associated with a steep decline in death rates by the second month of the crisis. Developing micro-enterprise in refugee camps: Eight relief agencies based in Gisenyi sinceincluding MSF nyirzgongo MERLIN, were in a position to respond, making available rehydration facilities at transit centres and way stations along the route.

At the time of writing a multi-sectoral emergency plan voclano being developed. Although engineering measures appear on the list of headings under natural disaster mitigation, and are important for preventing floods, for example, there is little scope for measures such as building barriers against lava flows at Csae volcano.

The economic activity which the programme revived, based on carpenters and builders, sent a buzz through the whole town and demonstrated clearly what a nyyiragongo the reintroduction of wages made to the economy. The draft plan allows for the relocation of betweento1.

There is abundant evidence from around the globe that post-disaster economies revive quickly if everyone has a little money to spend. The lake was pH 8 the organisms can only multiply in alkaline media, but are killed in fresh water. As the lava entered the lake it turned it acidic,poisoning the water and the fish.

Volcano Nyiragongo – Jan Tietze has performed the most comprehensive study of the gas problem in Lake Kivu. Tools API – Real-time data stream to power next-generation apps.

We worked with scientists from the Voolcano in assessing ground gas emissions in the city and its environs, and the impact of the lava flows on buildings was also considered.

As far as Lake Kivu is concerned, the most reasonably foreseeable worst scenario would be for the eruptive fissures to extend into the lake along the same line as the fractures from the Stuudy crater to Goma, which opened in January This is because the evacuation of populations is fundamental to mitigation in volcanic crises, but it is also usually a poorly managed nyiragonbo, even in developed countries.

Latrine pits should be dug deeper, but investigation of their porosity and contamination of the lake is needed.
