kmaFigure 6. Summary of seismic refraction profilesin the Red Sea. Velocities are in kms-l. Shaded area marks region of detailedseismic refraction survey. Earthquakeepicenters are shown by blackdots, and 1000 m isobath as a continuousline. Crustal thickness in km is givenas large, underlined numbers.330

Reflector S isindicated by a heavy line. After SEARLE and ROSS(1975). Vertical scale is in seconds of two-way traveltime. b) Seismic reflection profile with a 2:lverticalexaggeration showing a piercement dome of Miocene saltpossibly triggered by normal faulting from below.
