Mount Bangou is a LVC volcano included in the Western Highlands of Cameroon. This volcano is roughly elliptical and its lavas rest on a substratum made up of granitoids intrusive in metamorphic formations. This volcano has a summit caldera. The objective of the work is to establish a geological mapping and risk areas of this caldera and then highlight its model of establishment. The Mount Bangou caldera is in the form of a depression open to the east. This opening favors the drainage of water from the west to the east. DTMs and satellite images have been used and processed to produce thematic ...
Mount Bangou is a LVC volcano included in the Western Highlands of Cameroon. This volcano is roughly elliptical and its lavas rest on a substratum made up of granitoids intrusive in metamorphic formations. This volcano has a summit caldera. The objective of the work is to establish a geological mapping and risk areas of this caldera and then highlight its model of establishment. The Mount Bangou caldera is in the form of a depression open to the east. This opening favors the drainage of water from the west to the east. DTMs and satellite images have been used and processed to produce thematic maps that highlight several information (slopes, lineaments, land use, hydrography, areas at risk, geomorphology and lithology) concerning the study area and its surroundings. The qualitative analysis of natural risks reveals the presence of risks of geomorphological origin (rock falls, rock slides, and landslides). The risk map indicates that populations are exposed and to remedy this, recommendations have been proposed.
