Short Description   DSF_vp_vs_nt_2025 is a 3-D body wave velocity model for the upper crust around the central section of the DSF in northern Israel. It contains Vp, Vs, and Vp/Vs models obtained using local traveltime tomography based on Poisson-Voronoi cell projections (Fang et al., 2022).

Model Download DSF-vp-vs-nt-2025.r0.0.nc (see metadata) is the model in compressed netCDF-3 Classic format.
 
Depth Coverage 0 to 35 km
 
Area Northern Israel (latitude 32.12°/33.31°, longitude 34.8°/35.85°)
 
Data Set Description The models were created using a dataset of 1,469 seismic events (1.8≤M_W≤4.4) which produced 46,073 manually picked arrivals (26,265 P- and 19,808 S-arrivals) and were recorded by 60 permanent ISN stations.

Figure 1: Horizontal slices of VP (a-c), VS (d-f), and VP/VS (g-i) in 1km, 5km, and 10km depth. Color coding is scaled in accordance with the mean velocity at each slice (depth). Magenta lines in (e) and (i) indicate the locations of cross-sections shown in Figure 3 and Figure 4, respectively. MH: Mt. Hermon; MC: Mt. Carmel; NK: North Kinneret; EK: East Kinneret; GD: GF – DSF intersection; UG: Upper Galilee. ZB: Zevulun Basin; YB: Yizre’el Basin.

Figure 2: Vertical cross-sections of VP (a-d), VS (e-h), and VP/VS (i-l) are shown according to Figure 2f. Surface elevation and notable locations along each section are shown above each profile. Black dots show earthquake locations (during the years 2018-2024) within 5 km of the vertical profile. Gray rectangles indicate the location and inclination of suggested active faults. Dashed black lines indicate the estimated depth of the top of the Judea Group along each profile (after Rosenthal et al., 2015) HWBF: Hula Western Border Fault; HDF: Hula Diagonal Fault; HEBF: Hula Eastern Border Fault; KWBF: Kinneret Western Border Fault; JVF: Jordan Valley Fault.
