LANDSLIDE HAZARD ON THE SLOPES OF DABICHO RIDGE, WONDO GENET AREA: THE CASE OF JUNE 18, 1996 EVENT

Abstract

The eastern escarpment of the Awassa basin, rising to 2400 m.a.s,}. is characterised by steep slopes resulting from faulting and volcano tectonic collapse of the Awassa caldera. Landslide scars are prominent on this escarpment showing the potential danger of mass wasting. Here we present the nature and distribution of land slides which occurred in this area, along the Dabicho ridge on June 18 following the June 17. 1996 heavy rainfall (61 mm). At one site a family of eight-persons died due to the hazard. The necessity of undertaking extensive geological and geomorphological studies in order to prevent future disasters is discussed.
