The devastating cholera outbreak in in Rwandan refugees in Goma and the neighbouring camp areas was due to the total reliance of the population on Lake Kivu as the only source of drinking water, as the area is built upon the hard rock of old, porous lava flows there are no wells or rivers. The old lava rock is porous and the potential for the drainage of latrines to flow into the ground soil and then into the lake requires further investigation. The findings indicate that most, if not all, the lava drained from the crater lake out through the fissures, even as far as fissures in Goma itself. Lava covered 13 percent of the city, or approximately 1. Choose an example of one of the following: Nyiragongo Volcano Democratic Republic of Congo Saturday 19th January, The following information is based on preliminary reports from various government and news agencies that were received during the ongoing crisis.
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. The eruption has occurred in a part of the world Eastern Congo that is already afflicted by a humanitarian crisis and a chronic complex emergency involving armies and armed groups of at least six countries. Key considerations include the threat of physical violence, with people being more vulnerable as evacuees depending on where they go, and the threat to the property they leave behind. The and flank eruptions show similarities in terms of characteristics i. Thousands of people were left homeless when the lava destroyed their villages. The potential for carbon dioxide emissions has been known for a long time, as there are numerous dry gas vents in the area, especially near Lake Kivu, that emit carbon dioxide, and occasionally lead to deaths in humans.
The last event triggered fumarolic activity that was observed by local inhabitants. Warning of magma rising beneath Goma or Lake Kivu should be feasible, using a telemeter seismic monitoring network. This matter is addressed in the next section.
Mount Nyiragongo 2002 eruption case study
The high death rate, which was almost entirely attributable to diarrhoeal disease, was unprecedented for refugee populations up to that time. Food and fuel also became scarce, and water could not be boiled. Many residents lost their livelihoods in the volcanic eruption, and international non-governmental organizations NGOs now estimate unemployment levels at 95 percent, compared to approximately 80 percent prior to the eruption.

The town’s airport and the main road north to Uganda are reportedly cut and unusable to traffic. Population movement between Gisenyi and Ruhengeri has stopped.
Most fled to Goma, 30 eryption south of the volcano, while hundreds of others tried to enter neighboring Rwanda, but were turned away by border guards.
Goma Hospital is located at the base of Mt Goma, and was the only public hospital that remained open during the crisis. This analysis of the human health impact of eruptions at Nyiragongo volcano is directed towards the vulnerability and mitigation issues that require to be considered in a risk assessment for future eruptions, including the potential for a catastrophic gas burst at Lake Kivu.
Nyiragongo erupted at approximately 9: More pumping stations are needed in case the two existing ones are damaged by lava flows.
Once again, like the tragedy of Nevado del Ruizthe world fails to heed the warnings which are often staring us in the face. Volcano monitoring, therefore, has an important role in forewarning NGO’s and providing them with sufficient lead-time to prepare for nyiraglngo planned or unplanned evacuation of Goma.
The health risk from contaminated food and drinking water in Goma is exacerbated by these local geological features:.

Distributed drugs, basins, pans, buckets, and clothing Baptist World Aid: More information about the lveel eruptive activity can be found in the Current Activity page. As seen from a Rwandan Air Force helicopter, a small black cone was forming in what had been banana grove on Congo’s border with Rwanda.
Returnees will have to cope with a tide of steaming lava that plowed through the town, razing thousands of homes and killing dozens of people, and plunged into Lake Kivu. Tietze has performed the most comprehensive study of the gas problem in Lake Kivu. According to scientists, the two main hazards of immediate concern in a future eruption of Nyiragongo are: The WHO OPS should play a lead role for the health sector in co-ordinating planning and response to a renewed volcanic eruption.
United Nations officials said they were encouraging refugees to mass nyiragonog two camps some 12 miles from Gisenyi, where they could be more easily provided with shelter, supplies and sanitation. It is estimated that approximatelypeople were affected by the disaster.
The management of the volcanic crisis cannot be undertaken without including the other threats to life in the region, which is already in a humanitarian situation of disaster proportions. Problems continued with the system being overloaded and unstable for the power supply to the water pumping stations of REGIDESO, one of the two hospitals and the flour mill, for example.

In Januarythe opening of fissures lower down and directed towards Goma may reflect a new evolution for the nyiragomgo with eruptions caused by rifting. Security was the main reason for the rapid return of the population: There are three principal volcano scenarios presented in the draft plan that will need to be expanded upon in more detail as part of the Risk Assessment meeting.
The and flank eruptions caused long and very fast lava flows, which came from eruptive fissures on the volcano flanks. Emergency supplies of food BP5 – dried food and biscuits for three to five sfudy had not been stockpiled before the eruption. The presence of large quantities of methane erhption carbon dioxide stored at depth in Lake Kivu has been recognized and puzzled over by scientists since the early s,22 if not before.
