In particular, a huge school rebuilding programme generated budgets, employment and an explosion of small workshops making desks and chairs. The situation was exacerbated by the lava on which Goma was built, which made digging latrines impossible. These are associated with large ash emissions, which the prevailing winds blow towards the west. More specific measures to reduce vulnerability in a future eruption affecting Goma include organisational, logistical and engineering interventions to maintain and chlorinate drinking water and maintain power supplies in the city, and to stockpile and distribute emergency food rations. Thousands of people spent the night in safety on Mt Goma, where an unparalleled view of the eruption was obtained. These had not been possible to repair because of a shortage of money.

In January, the major fear of some volcanologists was a major phreato-magmatic explosion from an eruption of lava in the heart of Goma. All the patients reported that they had failed to chlorinate water taken from Lake Kivu. A repeat lava flow event and evacuation, followed by a rapid return to Goma before activity had declined, as occurred in January, would be especially hazardous, with the possible danger of phreato-magmatic explosions from renewed lava flows. Complex justifications are developed. An ash sample from the 22 January crater explosion was kindly supplied by the GVO and sent for analysis. The lack of fires spreading further in the city was an unexpected finding and significantly reduced the overall hazard. The roads would be inadequate for large loads of traffic.

Home Explore Case study of a Volcanic eruption: The possible release and dispersion of gases from Lake Kivu need to be modelled for hazard mapping purposes. The lack of security and fear of violence, the absence of democratic institutions, are the main issues affecting human ztudy in this and future volcanic crises.

A repeat lava flow event and evacuation, followed by stuvy rapid return to Goma before activity had declined, as occurred in January, would be especially hazardous, with the possible danger of phreato-magmatic explosions from renewed lava flows. In particular, a huge school rebuilding programme generated budgets, employment and an explosion of small workshops making desks and chairs. We interviewed three hospital doctors, one of whom was a foreign surgeon attached to an NGO, who had continued working in Goma Hospital in the days during and after the eruption.

The threat of an underwater volcanic eruption causing a violent 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.

This is one of the world’s most important volcanic crises. The importance of this is not sufficiently recognised in parts of the international community and needs to be reinforced as an integral aspect of contingency planning. Stuvy epidemic, Julyand lessons learned from the mass movement of refugees in Nyiragonbo However, the low mortality might make people underestimate the volcanic hazard in the future with consequently higher loss of life.

Many of refugees were located by Lake Kivu, but as there was no available way to purify and transport sufficient quantities of water most of the refugees consumed untreated water.

The lava lake level in January was not as high as inand the surface was solidified. Preventing an epidemic of cholera is a major priority for the health sector, including international relief agencies and NGO’s. Analysis of samples of lava from the different locations shows no major mineralogical differences in their composition as would be expected if their sources had been different i.

The high carbon dioxide nyiraagongo emitted at these sites were confirmed Fig. However, the political and humanitarian situation makes it unlikely that the population will heed warnings of an impending eruption and be prepared to evacuate part or whole of Goma as a precautionary measure.

Occupants have to pay to have the pits emptied. In contrast, the lava in the Munigi area moved more slowly tens or hundreds of metres per hourand solidified and flowed at a depth as great as m in some places.

Most of the increased attendances were children, with a disproportionate increase in the vase of patients with respiratory diseases between 23 January and 5 February peaked Januarydeclining to a more normal level by mid-February. A full hazard assessment has yet to be undertaken.

This reduced the access to the area for emergency supplies, which had to be brought in by road from Kigali or Bukavu, which have the closest airports.

The evacuation of Goma would therefore also reduce the loss of life expected in a gas nyirqgongo from Lake Kivu. 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. 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 Goma Volcano Observatory has had its technical capacity reduced during the humanitarian crisis, particularly over the last two years when studu have worked without any salary. 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. In Colombia in23, people died in the town of Armero and neighbouring settlements when they were destroyed by volcanic mudflows lahars triggered by an eruption of Nevado del Ruiz volcano.

This was a self-evacuation in the middle of an eruption, rather than a planned one on the basis of advice from the GVO.

A well co-ordinated relief programme was associated with a steep decline in death rates by the second month of the crisis. An ash sample from the 22 January crater explosion was kindly supplied by the GVO and sent for analysis.

The scientific institute in which the GVO is embedded does not appear to be functioning. Homes, schools, churches and businesses were ruined. Injured survivors of eruptions usually myiragongo from serious burns – a burns team should be sent as required, as skin grafting is often necessary to prevent long-term disability. The activity of the two volcanoes wtudy not been comprehensively monitored by scientists before, though a telemeter seismic network installed by a Japanese team in during the refugee crisis functioned until it was destroyed in the refugee mass movement in November It has yet to be shown that the population would leave on a planned basis, especially in the context of the continuing political crisis.
