East African Rift System - an Overview
The main characteristics of the East African Rift System are outlined from selected references. The difference between the Eastern Rift with high volcanicity on two domal uplifts as against the Western Rift of restricted volcanism, but sediment and lake filled grabens is pointed out. This is also evident from the earthquake activity: Large earthquakes occur in the Western Rift, whereas earthqua...

متن کاملHistorical volcanism and the state of stress in the East African 1 Rift System
21 22 Crustal extension at the East African Rift System (EARS) should, as a tectonic ideal, 23 involve a stress field in which the direction of minimum horizontal stress is 24 perpendicular to the rift. A volcano in such a setting should produce dykes and 25 fissures parallel to the rift. How closely do the volcanoes of the EARS follow this? 26 We answer this question by studying the 21 volcano...
