We use teleseismic data from all available broadband stations, permanent and mobile, in the entire area. Our processing method applies distance moveout correction, amplitude normalization, sign equalization and summation of traces with piercing points in 1° latitude times 1° longitude cells. The traces are stacked along the picked SV onset times. We obtain very clear signals from the Moho, less strong signals from velocity reductions below the Moho and again clear signals from the 410 km discontinuity. We also see locally velocity reductions just above the 410 km discontinuity. We show a number of profiles through the study area and hope to show maps of all seismic discontinuities. We compare our results with earlier observation.
