In KRISP 90 three profiles were acquired across and along the rift, targeting the north and central part, an axial line from Lake Turkana in the north, to Lake Magadi in the south (Mechie et al, 1994a;Keller et al, 1994); a cross-rift line from Lake Victoria in the west to Chandlers Falls in the east Masotti et al, 1997); and an eastern flank line, from Chandlers Falls to Lake Turkana (Prodehl et al, 1994b). In KRISP 94 two profiles were acquired in the southern part of the rift, a cross-rift line running from Lake Victoria, crossing the rift at Lake Magadi and terminating north of the Chyulu Hills (Birt, 1996;Birt et al, 1997;, and a profile ran from the eastern flank of the rift near Nairobi, to the Indian Ocean at Mombasa, crossing the Chyulu Hills (Novak et al, 1997a;Novak et al, 1997b).…”
