An initial velocity model based on VS30 for the region affected by the February 6, 2023 Turkiye earthquakes
This paper presents a VS30-dependent one-dimensional (1D) velocity model for the region affected by the February 6, 2023, earthquakes in Turkiye, which were marked by complex fault interactions along the East Anatolian Fault Zone. The proposed model utilizes VS measurements from 118 strong ground motion stations to develop a shallow VS structure (≤ 0.1 km), integrates deeper VS data from Acarel et al. (2019), and establishes a VS transition zone for intermediate depths (0.1 km to 0.6 km). The model evaluation indicated minimal bias despite some discrepancies. Additionally, compressional wave velocities (VP) and densities (ρ) corresponding to the VS30-conditioned VS model are provided. The findings from this study can be applied in a range of disciplines, including geotechnical and structural engineering, as well as ground motion simulations.
期刊介绍：
Bulletin of Earthquake Engineering presents original, peer-reviewed papers on research related to the broad spectrum of earthquake engineering. The journal offers a forum for presentation and discussion of such matters as European damaging earthquakes, new developments in earthquake regulations, and national policies applied after major seismic events, including strengthening of existing buildings.
Coverage includes seismic hazard studies and methods for mitigation of risk; earthquake source mechanism and strong motion characterization and their use for engineering applications; geological and geotechnical site conditions under earthquake excitations; cyclic behavior of soils; analysis and design of earth structures and foundations under seismic conditions; zonation and microzonation methodologies; earthquake scenarios and vulnerability assessments; earthquake codes and improvements, and much more.
This is the Official Publication of the European Association for Earthquake Engineering.
