资源简介：
OpenAmp is an open-source, consistently curated, high-quality database of earthquake site amplification functions derived from instrumental recordings, accompanied by a comprehensive suite of site metadata, for 1,742 K-NET and KiK-net strong-motion recording sites in Japan. The site metadata builds upon the site database of Zhu et al. (2021) and introduces several new parameters, including the site-specific spectral decay parameter (<i>κ</i><sub>0</sub>), the standard deviation of the horizontal-to-vertical spectral ratio of earthquake recordings (<i>σ</i><sub>HV</sub>), and site dimensionality index (<i>I</i><sub><em>1D3D</em></sub>). A distinctive feature of OpenAmp is the inclusion, for the first time, of a diverse set of vector-based parameters and proxies, including quarter-wavelength velocity (V<sub>s,qwl</sub>), and frequency- and scale-dependent topographic metrics. The (linear) site amplification functions are derived from weak-motion recordings using a generalized inversion technique in the Fourier domain.<br><b>File description:</b>‘<i>OpenAmp_v1.0_HumanReadable.xlsx</i><i>’</i>: OpenAmp database interpretable by human experts;‘OpenAmp_v1.0_MachineReadable.csv’: OpenAmp database directly readable by machines;‘VariableDescriptions.xlsx’: Definition of variables in ‘OpenAmp_v1.0_MachineReadable.csv’;‘Plot_Amp.zip’: Plots of amplification functions in comparison to those of Nakano et al.
