East Africa Rift System

Airbus Defence and Space have completed a geological study incorporating territories from north to south; Eritrea, Djibouti, Somaliland, E Ethiopia, SE border area of Sudan, Uganda, Kenya, Rwanda, Burundi, E border of Democratic Republic of Congo, Tanzania, Malawi, border area of SE Sudan, Mozambique and the border zones of Zambia, Swaziland and South Africa.

A new addition to the study is Western Madagascar including the interpretation of major offshore structural features.

East Africa Rift System

An area of approximately five million square kilometers is covered by this unique, integrated and consistent study. Interpretation is based on 15m Landsat 7 ETM+ imagery combined with a 90m SRTM elevation model, with regional bathymetry and magnetics data used for the offshore interpretation surrounding Madagascar. 

The interpretation study includes:

  • Interpretation of surface geology and structure at 1:100 000 – 1:250 000 scale
  • Capture of major drainage channels and water bodies
  • Oil seep locations as points and vectors of slick outlines 

Study Deliverables

The final study deliverables consist of the digital data on DVD as an integrated ESRI ArcGIS project, containing the following data and interpretation:

  • Structural and stratigraphic interpretation (supplied as ArcGIS Geodatabase)
  • Global Seeps (extract from the oil seeps database covering major rift lakes)
  • Seismic events
  • Mineral occurrences
  • Major drainage channels and water bodies
  • Names of important structural features
  • 15m Landsat 7 ETM+ imagery in a 742 (RGB) band combination
  • SRTM 90m DEM in shaded relief form
  • 100m contours
  • Radar imagery for key areas

Also included is a full written report with illustrations containing the results from
the geological interpretation and seeps study which are discussed in relation to published maps, reports and papers. In addition 31 hardcopy map sheets are supplied at 1:500 000 scale.

Airbus Defence and Space have extended their East Africa Geological Interpretation study to also include Madagascar.
