“…Gas explosions occurred in Cameroon in 1984 and 1986 in Lakes Monoun and Nyos respectively; the Lake Monoun explosion killed 34 people whilst the Lake Nyos gas explosion killed 1750 people, over 3000 cattle, and displaced 3000 people (Aka et al 2008;Le Guern & Sigvaldason 1989). Volcanic eruptions are limited to the activity of Mount Cameroon, currently the only active volcano on the CVL, with the last eruptions in 1999 and 2000 (Suh et al 2003;Favalli et al 2011). Volcanic hazards like ash fall, mudflows, volcanic landslides, lava flows and volcanic gases are common (Thierry et al 2008).…”

At the 2005 World Conference on Disaster Risk Reduction held in Hyogo, Japan, 168 countries including Cameroon adopted the Hyogo Framework for Action, committing to take action to reduce human and socio-economic disaster losses. Geotechnology, Environmental Assessment and Disaster Risk Reduction was commissioned by the Global Network of Civil Society Organisations for Disaster Risk Reduction as the coordinating organisation in Cameroon to evaluate progress in implementation of the framework from the civil society perspective, particularly the role of local governance in disaster risk reduction (DRR). Seven regions of the country were identified for evaluation, where people have suffered losses from disasters during the last three decades. Three approaches were used: administration of questionnaires; consultations with local communities; and four case studies. It was found that there was significant scope for improvement on individual local governance indicators, and that effective progress depends on:1. level of achievement in the decentralisation process currently under way.2. adoption of a participatory approach to DRR.3. clear distribution of roles in the DRR process.4. adequate allocation of necessary financial and human resources.5. enhancement of capacity of local communities to prepare for and respond to all types of disasters.Creation of an independent body to carry out fundamental research, forecast new and emerging hazards and manage all disasters in the country will contribute greatly to moving things forward.

“…Déruelle et al 2007;Njome and de Wit 2014). Mount Cameroon erupted seven times in the 20th century, the last two confirmed eruptions taking place in 1999 and 2000 (Suh et al 2003. The eruptive style generally comprises effusive and Strombolian-style activity, the latter mostly confined to the broad summit region.…”

“…Mount Cameroon in SW Cameroon is one of the largest (4095 m high) flow-dominated volcanoes on Earth, and one of the most frequently active volcanoes in Africa (Siebert et al 2010). It has a NW-SE elongated shape of about 50 by 35 km and is part of the Cameroon Volcanic Line, a chain of Cenozoic volcanic structures extending about 2000 km from the Gulf of Guinea to the Adamawa Plateau in Tchad (e.g.…”

The scientific evaluation of hazards and risks remains a primary concern in poorly known volcanic regions. The use of such information to develop an effective risk management structure and risk reduction actions however also poses important challenges. We here present the results of a series of focus group discussions (FGDs) organised with city councillors from three municipalities around Mt Cameroon volcano, Cameroon. The Mt Cameroon area is a volcanically and tectonically active region regularly affected in the historical past by lava flows, landslides and earthquake swarms, and has a potential for crater lake outgassing. The lower flanks of the volcano are densely populated and the site of intense economic development. The FGDs were aimed at the elicitation of (1) the knowledge and perception of geological hazards, (2) the state of preparedness and the implementation of mitigation and prevention actions by the municipalities, (3) the evaluation of the effectiveness of the structure of communication channels established to respond to emergency situations, and (4) the recovery from an emergency. In all three municipalities stakeholders had good knowledge of the risks, except for processes never experienced in the region. They generally grasped the causes of landslides or floods but were less familiar with volcano-tectonic processes. Stakeholders identified the lack of strategic planning to monitor hazards and mitigate their impacts as a major weakness, requesting additional education and scientific support. Response to natural hazards is mostly based on informal communication channels and is supported by a high level of trust between local scientists, decision makers and the population. Actions are taken to raise awareness and implement basic mitigation and prevention actions, based on the willingness of local political leaders. The strong centralisation of the risk management process at the national level and the lack of political and financial means at the local level are major limitations in the implementation of an effective risk management strategy adapted to local risk conditions. Our case study highlights the need for earth and social scientists to actively work together with national and local authorities to translate the findings of scientific hazard and risk assessment into improved risk management practices.

“…1). Volcanism along this line began in the Eocene by the formation of Bamoun plateau between 51.8 and 46.7 Ma (Moundi et al, 2007) and Mount Bangou between 44.7 and 43.1 Ma (Fosso et al, 2005) and continues until the present day on Mount Cameroon (Suh et al, 2003). The products of the CVL volcanism are mainly rhyolites, phonolite, trachyte and basalt.…”

Hazards related to pyroclastic density current continue to raise victims on many volcanoes in our planet. The Cameroon is not spared to this type of hazard because deposits of pyroclastic flows and surges are found on Mount Bamenda; products of this volcano are relatively young (27-0 Ma). Besides Mount Bamenda, Mounts Bambouto and Oku are the only volcanoes located in the central part of the Cameroon Volcanic Line where these ignimbritic deposits are found. Several factors highlight dangerousness and damage that can cause ignimbritic flows on the flanks of this volcano. This is essentially the high aspect ratio of these ignimbrites, the important population (about 750,000 people) that lives on the slopes and around the volcano. In order to have an idea of a nowadays ignimbritic eruption scenario on Bamenda volcano, the Anisotropy of Magnetic Susceptibility (ASM) method is used in this study to highlight the palaeoflow in ancient deposits of ignimbrites which are mostly discontinuous and isotropic. Results of AMS study are used to produce map of hazards and assess risks that may be related with such eruptions in Bamenda volcano.
