CASE STUDY NYIRAGONGO ERUPTION 2002
A detailed report by eyewitnesses in Rusaya 8 km SW of the summit indicated that collapse started at on 22 January, coinciding with a series of felt earthquakes. This area could present future slope stability problems. The January eruption of Nyiragongo volcano was heralded by precursory phenomena detected since March by volcanologists of the GVO. Benches in the steep-walled, 1. Abnormal odors of hydrocarbons were reported in many parts of the city, prompting the use of a portable infrared spectrometer allowing in-situ gas analysis. Developing micro-enterprise in refugee camps:
A displaced mud-brick house located on the main fracture in Monigi village following the January eruption of Nyiragongo. User-managed public health promotion in the Mekong Delta, Vietnam. It was no secret that they were going to sell the goods, and that the ensuing flood of cheap aluminium pots or plastic sheets would debase the local market and make things worse for small traders. The two types of lavas were emitted simultaneously and did not exceed 2 m thick. Intermittent phreatomagmatic explosive activity inside Nyiragongo crater persisted after the collapse. Most of these flows were of aa-type, less fluid, black, and m thick.
Nyiragongo DR Congo 1. These sites are located in the middle of a small village and constitute a major attraction for cooking and for children who play nearby. Lake Kivu m deep is known to contain an immense amount of both CO 2 1, times that in Lake Nyos, Cameroon and methane stored in solution in its waters.
Unpleasant odors and experiences were reported by swimmers in Lake Kivu before the eruption, again ascribed to gas emissions. Flames of burning gas and vegetation were observed and analyzed in different parts of the flows, both inside and outside the city.

Food security in the occupied Palestinian territory. Very fluid lava flows, only cm thick at their source, moved across the forested SE slopes of Nyiragongo and rapidly cut the road going N from Goma.
In Novembernew fumaroles appeared on the N floor of Shaheru crater itself. Could the clue be eruptjon the agency stickers plastering every aid vehicle in Goma, and the agency logos everywhere?
Family kits, providing household items, were important nyiragong greatly needed, but everything in the kit could be bought in Goma. Families were made to line up for hours to sudy meticulously counted and packaged items, and the length of the procedure alone led to frustration, and ultimately to temptation and impersonation.
Another eruptive fissure opened at at 2, m elevation figure 15 2 km W of Kibati. Most of the gas bursts occurred at places or in areas that are broadly aligned with the N-S fracture system cutting the volcano and where ground gas emanations were persisting.

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. This figure compares well with the bulk volume of lava flows, suggesting that these mainly derived from the lava stored in the crater and upper conduit of the volcano.
Global resource consumption and security 3. The humanitarian situation and response in the OPT. Would the misuse of money in Goma have been any worse than the misuse of goods? Further study will be necessary stuudy elucidate the origin of that methane.

They measured depth, temperature, pH, electrical conductivity, turbidity transparency to white lightand dissolved-oxygen content. The two types of lavas were emitted simultaneously and did not exceed 2 m thick. BBC News – Congo volcano ‘kills dozens’. It is most likely that this chilled crater floor, although thick enough to initially resist falling, had been weakened by the lava drainage during January.
Many dead fish were seen in and around these areas. For example, at the lava delta, when molten lava entered Lake Kivu, and at Goma when bulldozing the eruptioh flows suddenly depressurized steam produced by the high temperature of lava flows along the ground.

Eyewitnesses to these events saw that the gas bursts shortly followed strongly felt earthquakes and were accompanied by strong smells of hydrocarbon gas. You should use the ‘Five W’s” subheadings to give your case study structure. Human development and diversity 5.
Fractures left openings m deep. Yet aid workers persisted in treating people like children who could not be eruptoon with their pocket money. Width is about 25 m and depth m.
The strong gas smells and the elevated methane concentrations were taken as evidence of a methane-driven origin for the explosions. Photo by Jean-Christophe Komorowski. Chemical analyses of lavas from the January and January Nyiragongo eruptions.
In several places m distant from lava flows, these gas bursts ripped through cement and stone pavement in Goma’s houses and streets.
