    Abstract:

    Abstract: Mount Bambouto is a polygenic stratovolcano of the Cameroon Volcanic Line, built between 21?Ma and 4.5?Ma. It is situated approximately 200?km NE of Mount Cameroon, between 09°55′ and 10°15′ longitude east and, 05°25′ and 05°50′ latitude north. The volcano covers an area of 500?km2 and culminates at 2740?m at Mélétan dome and bears a collapsed caldera at the summit (13?×?8?km). Mount Bambouto is characterized by several natural hazards of different origins: meteorological, such as landslides and rock falls; anthropogenic, such as bushfires, tribal wars and deforestation; and volcanological, such as volcanic eruption. The thematic map shows that 55–60% of the caldera has high probability of occurrence of mass movement. The caldera has a high population density (3000 inhabitants), which increases the level of risk, evaluated at approximately $US3.8 million for patrimony, 3000 civilian deaths and destruction of biodiversity.
