In an integrated geoscientific project wie plan to study the crustal and upper mantle structure in the Dead Sea Region and to image the Dead Sea Transform Fault. The field experiment consists of several mutually dependent and interlocked geophysical experiments:1. Seismic/Seismology: Wide-Angle Reflection/Refraction, Near-Vertical Reflection, Controlled Source Array, Passive Array; 2. Electromagnetics: Magnetotellurics, Time Domain Electromagnetics; 3. Magnetics and Gravimetry; 4. Integrative Interpretation. By determining the seismic velocities, the anisotropy, the electrical conductivity, and the density of the crust and the upper mantle, together with the same parameters for the fault(s) in the crust, in addition to their depth, shape, and width, we hope to be able to understand the dynamics and geological development of this large transform via an integrative interpretation that will include, if possible, the source mechanisms of local earthquakes. We furthermore expect to contribute to the understanding of the working of shear zones, their seismic risk, and their geodynamic role in Plate Tectonics.

在一个综合地球科学项目中，我们计划研究死海地区的地壳和上地幔结构，并对死海转换断层进行成像。野外实验由几个相互依赖、相互联系的地球物理实验组成：1.地震/地震学：广角反射/折射、近垂直反射、可控震源台阵、被动台阵; 2.电磁学：大地电磁学，时域电磁学; 3.磁性和重力; 4。综合解释。通过确定地壳和上地幔的地震速度、各向异性、电导率和密度，以及地壳中断层的相同参数，除了它们的深度、形状和宽度之外，我们希望能够通过综合解释来理解这一巨大转变的动力学和地质发展，如果可能的话，局部地震的震源机制。此外，我们希望有助于了解剪切带的工作，他们的地震风险，以及他们在板块构造中的地球动力学作用。
