In its Southern segment, which extends from the Gulf of Aqaba to the Sea of Galilee and the Hula
depression in south Lebanon, the Dead Sea fault system strikes in a more or less N-S direction. However, when entering Lebanon through the Galilee heights, it changes into a more complex system of braided strikeslip faults (Wally 1988), known as Roum, Yammouneh, Hasbaya, Rachaya, and Serghaya. The most significant among these faults is the Yammouneh which forms the western boundary of the Bekaa valley, and which represents the main northward continuation of the Dead Sea fault system to the Ghab fault in Syria, and then on to the Taurus-Zagros thrust in southern Turkey.
