AB: Beginning in September 2006, a temporary network of 30 broadband and 45 short-period seismic stations has been set up on both sides of the Dead Sea Basin (DSB). The aperture of the network is 70 km E-W and approximately 70 km N-S. It is anticipated that the network be kept in operation till March/April 2008. Data are continuously recorded at 100 Hz and 200 Hz sample frequency for the broadband stations and short-period seismic stations, respectively. The aims of the project are (1) to investigate the crust and upper mantle discontinuities with the receiver function method, (2) to investigate anisotropy in the crust and upper mantle from shear wave splitting, and (3) to study local seismicity in the area. First preliminary receiver function analysis reveals a crustal thickness of about 30-35 km in the eastern part of the DSB and possibly an upper mantle low- velocity layer. It also shows a basin which is mainly filled with salt about 10 km thick beneath the Lisan peninsula.
