Abstract Within the framework of the international project DESIRE (Dead Sea Integrated Research Project) a local seismological network was operated in the Southern Dead Sea area as a co-operation between the GFZ Germany, GII Israel, NRA Jordan and An-Najah National Univer-sity Palestine. From October 2006 to March 2008 about 65 short period (38) and broadband (27) instruments recorded continuously the seismicity of the Dead Sea basin. This investiga-tion aims in studying the deeper structure of the Dead Sea area based on the distribution of the local seismicity. About 500 local events have been recorded and more than 300 have been processed up to now. A dominant feature in this first part of the dataset we found a cluster of 78 earthquakes, occurring in February 2007, including multiplets. We determined a 1D-reference model of P- and S-velocities using Velest (Kissling et al., 1994). The model shows a high velocity increase between 6 and 10 km depth. This could be related to a prominent reflector found in the results of the wide angle reflection experiment in the area in 2006 (Mechie et al., 2008). The station corrections suggest a 2D structure with the basin in the middle and the shoulders on the east and west. Additionally the results are compared with receiver function and magnetotelluric studies, part of the DESIRE project.
