In June-July 2003, a series of important landslides happened in the Monts Bamboutos (Cameroon) and in their surroundings, causing a large number of casualities and leaving many people homeless.
In particular, the landslide at Maghah caused 20 deaths, the one in Batibo 3 deaths, the one in Bafou 2 deaths, and the most important, at Wabane caused one death and very important material damage. 309 houses have been destroyed.
These landslides are associated to the very heavy precipitations of the rain season in 2003 (rain season from end of May to end of October).
They are becoming now a recurrent threat in these areas which are located in very strong relief of volcanic origine.
In front of what is now considered a permanent high risk, and in the expectable perspective of generalized landslides and of a major disaster in these densely populated mountains, the local and national authorities remain powerless with regard to the decisions to be taken.
In any case, accurate regional mapping was considered an urgent necessity, to determine the risk areas, and to define the sectors where the population could eventually be moved into safety.
