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. We were shown the location of these vents at the roundabouts at Seigners and Bralima, m or more from the end of the airport runway. In the first month of the influx, an estimated 50, refugees had died. Fluoride contamination of drinking water from ground sources is not uncommon in the East Africa Rift Zone. This is one of the world’s most important volcanic crises. The lava from high up travelled with velocity of tens of kilometres per hour and solidified to a depth of cm, though marks on trees indicate that it flowed to a depth of 1.
Even so, facilities were less well prepared than they could have been and some of the deficiencies of resurfaced again. 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. Due to the hardness of the rock, the depth of latrines is generally less than ideal, not more than 1. Either of these events could lead to catastrophic loss of life. 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.
These scenarios are also good reasons for not returning to the city after an eruption until the activity has clearly declined. The consequences to health in terms of trauma and infections of these impacts were relatively small, especially in comparison to the potential hazards from the lava flows 6. Even so, facilities were less well prepared than they could have been and some of the deficiencies of resurfaced again. There was no immediate danger of starvation.
Location Maps – Country maps for your reports and presentations. 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.
As many aspersons left, whilst a substantial number of people stayed behind in the area of the town between the lava flows and also in the western part of the city. 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 Nyiragongo volcano. During the first month after the influx, almost 50, refugees died, most in the streets of Goma, in explosive epidemics of diarrhoeal disease caused by V.
Volcanoes – Edexcel – Revision 7 – GCSE Geography – BBC Bitesize
By early August a standardized health surveillance system was established. The town is a busy commercial centre, a hive of economic activity and the main point of entry for goods from the outside world for much of eastern Congo.
The lava from high up travelled with velocity of tens of kilometres per hour and solidified to a depth of cm, though marks on trees indicate that it flowed to a depth of 1. Baxter on the health aspects for WHO. Political vulnerability, which includes the humanitarian crisis, will profoundly affect how the people regard warnings about impending eruptions and their beliefs in taking actions such as evacuation to protect themselves.
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. Lava invaded the airport at aroundand was at the Cathedral by two hours later.
Contact Us – Ask questions and suggest improvements. The presence of large quantities of methane and carbon dioxide stored at depth in Lake Kivu has been recognized and puzzled over by scientists since the early s,22 if not before.
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.
Volcanoes – Revision 3 – KS3 Geography – BBC Bitesize
A risk assessment should ideally be completed before the end of The main descriptive points in his report23 are as follows:. This type of eruptive activity is not usually dangerous to life except in the very fluid flows that can move very fast in eruptions of Nyiragongo.
People in Goma were spectators of the events until the lava flows began to enter the city towards the late afternoon, when they too vase to leave by the roads east and west out of the city.
Emergency supplies of food BP5 – dried food and biscuits for three to five days had not been stockpiled before the eruption.
Case study of a Volcanic eruption : Mt. Nyiragongo
Complex justifications are developed. Another important aspect, in the longer term, is mitigating risk by planning the future development of Goma in such a way as to minimize the impact nyiraongo a future eruption. Many earthquakes around were felt on the 19 January, with 10 large ones, some of which caused at least two houses to collapse. 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.
It is arguable that losses would be no less than they are in caae food distributions.
Mount Nyiragongo 2002 eruption case study
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. Car traffic was held up for two hours by the border guards.
Emergency planning for a major eruption of Nyiragongo presents several unique challenges. A mass immunization programme was instituted in one camp to combat the outbreak there.
