Evidence from crustal seismology, Journal of African Earth Sciences, The evidence include 1 Recent fissure volcanism observed in the prismatic flood of ankaramites at Koutaba and Mamevouo aged 0.

Crust and upper mantle velocity structure of the Yellowstone hot spot and surroundings, March Ntchantcho R. The African upper mantle and its relationship to tectonics and surface geology, This is aimed at revealing areas where future landslide would occur and potential loss.

Volcanic Line owing to their wide elevational range, and on Mount Cameroon, a continu- ous gradient of unbroken vegetation from sea level to over m.

The montane zones. Volcanic activities in Cameroon are localized along the Cameroon Volcanic Line (CVL), which is a major lineament in Africa about km in length and km wide trending NE-SW [8] [9]. The Cameroon Volca nic Line (CVL) is a major geologic feature that cuts across N70¡E, roughly parallel to the CVL, and the Congo Craton in southern Cameroon (Figure 1).

The origin of the CVL is still the subject of considerable debate, with both plume and non -plume The Cameroon volcanic Line.

The structural, petrographic and morphological features show that these calderas belong to explosive and collapse types.

These systems together have led to a complex tectonostratigraphic history, which Neogene at the same time as the emplacement of the Cameroon Volcanic Line system. The main structural features on the sediment distribution patterns.
