Abstract
In this study we propose the SoilGrid database with predicted soil properties down to 2 meters depth and geological maps of Japan as geotechnical indicators with the potential to explain nonlinear site-effects. To test these indicators, we measure the nonlinear site- response in the Japanese Kiban–Kyoshin Network (KiK-net) as the change in amplitude and shift in frequency between strong-motion events and the linear site-response. These measurements are then fitted to a hyperbolic tangent function. We plan to use the coefficients and parameters from the fitted hyperbolic tangent function to explore the correlation between the geotechnical indicators and sites with strong nonlinear soil-behaviour.
