North Afar has been mainly measured in 1968 by Prakla-Seismos GmbH on behalf of the Salzdetfurt AG, Hannover (Ochse and Ries, 1972). Gravity values of the Geophysical Observatory, Haile Sellassie I University, Mohr and Rogers (1966), Mohr and Gouin (1967) Gouin and Mohr (1964) were used as well. South Afar was covered by approximately 1000 gravity measurements established in 1969 and 1970 by Mackris et al. (1970, 1971). A total approximately 1,800 stations were uniformly reduced and compiled into a map of 10 mgal isogals. The mass reductions were spherical to Hayford zone O2 with uniform density of 2.67 g/cm3. The gravity data have been reduced to the mean sea leavel. The normal field was computed by the international formula of 1930. The map was extended along the coast of the Read Sea to the Sudan border by data measurements that C. Morelli (personal communication, 1971) put at our sisposal. The Red Sea data have not been corrected for topographic effects.
