Developing micro-enterprise in refugee camps: 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. Scientific studies are urgently needed to constrain the present volcanic hazard. A gas release from Lake Kivu would be most likely localised around the location of a lava emission along the main fissure line from the summit crater to the lake, in other words, near Goma. The main flow also continued flowing into the lake for several days through the lava tube and the centre of the flow was still moving on 18 January in Goma.
The eruption began without warning at Eight relief agencies based in Gisenyi since , including MSF and MERLIN, were in a position to respond, making available rehydration facilities at transit centres and way stations along the route. The main flow also continued flowing into the lake for several days through the lava tube and the centre of the flow was still moving on 18 January in Goma. The fluoride concentration on 21 January was measured at 4. Co-ordination of the international scientific effort is being provided through UN-OCHA and monitoring of the Nyiragongo and Nyramuragira volcanoes and Lake Kivu must be established as a matter of urgency.
The geomorphology of the lake, including its great depth and proximity to an active volcanic centre, underlie its present hazardous, gas-laden state. Tietze has performed the most comprehensive study of the gas problem in Lake Kivu. Work projects could have satisfied the work ethic.
The very fluid lava flows were not considered to be a major threat to Goma. Cholera risk in Goma. A visit to the town of Masisi was made to learn more about the impact of ash falls from the volcanoes on human and animal health.
The roads would be inadequate for large loads of traffic.
Access in and out of the city is relatively free-moving using the single main roads out to the east and west, but these could easily become congested during an evacuation of the population except that they would mostly move on foot.
A slight increase in turbidity was found in the sample for 21 January, which colcano for about a week. However, the massive fissuring of the flank of the volcano in Januaryextending 18 km from the crater to Goma, is strongly suspected by scientists to have a tectonic or rifting origin, at least in part, which implies that the volcano has moved to a new and more hazardous state, with the risk in future eruptions of fractures and lava emissions arising in Goma itself, or even deep within Lake Kivu.
The risk of an epidemic is greatest with an evacuation of Goma, or a return to Goma before its shattered lifelines are restored as occurred on January 19, In the first month of the influx, an estimated 50, refugees had died. About 30, square kilometres of land west volcno the volcano was destroyed by volcanic fallout, including 5, square kilometres of land in the nearby Virunga National Park, endangering chimpanzees and other wildlife.
The loss of the commercial centre and housing has meant a loss of jobs and disruption of the economy. Humanitarian response in the occupied Palestinian territory: The threat of an underwater volcanic eruption causing a ccase outpouring of gases was considered by Tuttle, Lockwood and Evans in a USGS Open File Report following a brief field visit to the lake by the authors in and it was not published.

The animation actually shows two plumes coming from two locations close to each other: The WHO OPS should play a lead role for the health sector in co-ordinating planning and response to a renewed volcanic eruption. Cholera epidemic, Julyand lessons learned from the mass movement of refugees in November The potential for outbreaks of diarrhoeal diseases from drinking contaminated water was therefore present immediately after the eruption, the risk falling rapidly in the first few days as potable water supplies were restored.
Emergency health measures include the provision of chlorinated water along evacuation routes and in refuge areas, and adequate medical cover for the treatment of cholera and other enteric diseases.
The epidemiological surveillance programme showed a large cade in total attendances at the two hospitals and 18 functioning primary health care centres after the eruption Fig.

According to volcanologists, this eruption was triggered by tectonic nyriagongo 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 a deeper conduit nearer Goma.
The Rwandans did not African Rift Valley welcome them and gangs threatened the refugees unless they returned home.

Until the latest eruption, the hazard of Nyiragongo was thought to be limited to the hydrostatic pressure of the lava lake and the risk of breaching the thin wall of the crater.
