A sudden re-opening of the eruption fracture at m elevation allowed the lava lake in the summit crater to drain out violently. Family kits, providing household items, were important and greatly needed, but everything in the kit could be bought in Goma. Scientific forecasting and relief agency preparedness and response.

Sulfur deposits on fresh lava at Nyiragongo, The area is subject to earthquakes and volcanic eruptions, as well as dangerous phenomena related to volcanic gases.

About 30, square kilometres of land west of the volcano was destroyed by volcanic fallout, including 5, square kilometres of land in the nearby Virunga National Park, endangering chimpanzees and other wildlife. It was however reported that the Nyamuragira volcano, located 14 km northwest of the Nyiragongo volcano, also erupted during the July-August period. The draft plan allows for the relocation of between , to1. People in the area were contracting stomach illnesses as well as respiratory and bone diseases. The challenges to the scientists were to rapidly establish the hazards of the lava flows and their associated eruptive phenomena in such a densely populated area. The evacuation of Goma would therefore also reduce the loss of life expected in a gas release from Lake Kivu. Established displacement camps, coordinated relief efforts Government of South Africa:

In contrast, Nyramuragira volcano erupts on a much more frequent basis and a new eruption could occur any time in the near future. ReliefWeb Informing humanitarians worldwide.

The health risks of evacuating a population the size of Goma for weeks or months should also be evaluated for risk assessment purposes Appendix 2.

Lush vegetation on the slopes of Nyiragongo volcano right.

According mg volcanologists, this eruption was studg by tectonic spreading of the Kivu rift causing the ground to fracture and allow lava to flow from ground fissures out of the crater lava lake and possibly from caxe deeper conduit nearer Goma.

The mystery of its “column of fire” was not revealed untilwhen the volcanologist Haroun Tazieff climbed down into the crater below its vapour clouds to find a vast, incandescent lake of molten lava. Mazukus “evil winds” in Swahili are low-lying areas with CO 2 vents. A slight increase in turbidity mr found in the sample for 21 January, which lasted for about a week. If you have heard of Nyiragongo before this course, it is probably because the last refuges of the mountain gorilla are found within the densely-vegetated slopes of the Virunga volcanoes.


A survey of several well-known Mazuku on the outskirts of Goma and towards Sake was performed. But the effectiveness csae this more visible role for the GVO and its effect on its credibility with the population at large have yet to be established and it will be important in the foreign scientific initiatives to review these issues on a regular basis.

The fear of giving cash New aid workers are warned by older and wiser colleagues never to give cash to beneficiaries. A medical team at Gisenyi Hospital also worked through the eruption. However, seismic activity continues at a high level and scientists are concerned that tectonic rifting may still be occurring.

Case study of a Volcanic eruption : Mt. Nyiragongo

Primary country Democratic Republic of the Congo. Large lava fountains are associated with the flank eruptions of Nyramuragira. The centre of the outbreak was probably Goma. However, a wide array of volcanic hazards makes Goma a dangerous place to call home. The high death rate, which was almost entirely attributable to diarrhoeal disease, was unprecedented for refugee populations up to that time.

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 very fluid lava flows were not considered to be nyragongo major threat to Goma.

There was a lot of lava to clear from the airport runway, for instance; there were roads to be reopened. There were tonnes of stock in a warehouse in the western part of Goma, and this could not initially be accessed from the east because of the city being divided by the two lava flows.


The lack of security and fear of violence, the absence of democratic institutions, are the main issues affecting human vulnerability in this and future volcanic crises. 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 All the patients reported that they had failed to chlorinate water taken from Lake Kivu.

Other Donor and International Organization Assistance Relief Commodities On January 23, ECHO provided five million Euros in assistance for the purchase of water, medications, and food aid and to assist nyiragonvo coordination and logistics in the region.

There was no immediate danger of starvation. Brief guidance on the health hazards of gas and ash emissions from volcanoes is given in Appendix 3, which could form the basis of an information leaflet.

The speed and scale of the influx of these ethnic Hutus overwhelmed the world’s response capacity. A model for this was the methodology used in the Montserrat volcanic crisis Appendix 2.
