Vs30 Database for Israel

This database integrates measured subsurface geophysical profiles with surface geological and topographic features for 509 sites. Each record includes site metadata (ID, WGS84 coordinates, and measurement method), and a station_name field indicating whether the measurement is associated with the Truua seismic network. The dataset contains measured shear-wave velocity (Vs) profiles—consisting of up to 12 layer thicknesses (h) and their corresponding velocities (Vs), a half-space velocity, and the calculated Vs30—alongside categorical geological age and lithology (Sneh et al., 1998; 1:200k). The dataset includes the depth to bedrock (depth to tj), defined as the top of the Upper Cretaceous Judea Group carbonate unit (Fleischer and Gafsou, 2000; Zaslavsky et al., 2001). Topographic features, provided by the Survey of Israel and computed via QGIS SAGA tools (Conrad et al., 2015), comprise multi-scale slope gradients (10 m to 2000 m) and seven geomorphological metrics (Convexity, Texture, Roughness, VRM, TRI, Ridge Level, and Total Curvature) provided at 120 m, 300 m, and 500 m spatial resolutions. Coordinates for specific private-sector sites cannot be shared due to proprietary restrictions and are set to NaN. All other missing parameters or empty layers are also denoted as NaN.
