Abstract
<jats:p>Abstract. The Gulf of Aqaba is an elongated basin (~180 x 20 km) with depths reaching 1850 m. It represents the southern segment of the Dead Sea Transform (DST), which is one of the largest transform fault zones in the world. The opening of Gulf of Aqaba is thought to have originated from the relative displacement of the African and Arabian Plates. According to historical and recent earthquake records, it is seismically active. In this study, we present the first 3D model of seismic P and S velocities beneath the Gulf of Aqaba area based on the results of passive travel time tomography. The tomographic inversion was performed based on travel time data fr...
