Composite cones / strato volcanoes.

These are usually large volcanic cones with fairly steep slopes. They are made of alternate layers of ash and lava ejected through  a central vent over a long period of time. Each layer of lava over ash represents a phase of eruption.  Examples of composite cones/ strato volcanoes in East Africa are Mt. Kilimanjaro, Meru, Mt Mubabura on Uganda – Rwanda border
