This database contains site characterization parameters directly derived from available velocity profiles, including average wave velocities, bedrock depths, and velocity contrast. Meanwhile, it also consists of parameters obtained from earthquake horizontal-to-vertical spectral ratio (HVSR), e.g., peak frequency, amplitude, width and prominence. In addition, the site database also comprises topographic and geological proxies inferred from regional models or maps. Each parameter is derived in a consistent manner for all sites. This site database can benefit the application of machine learning techniques in studies on site amplifications. Besides, it can facilitate, for instances, the search of the optimal site parameter(s) in depicting site amplification, the development and testing of new or existing prediction models or methodologies.

This zip file contains earthquake HVSR data, including metadata and plots of automatically identified peaks (frequency, amplitude, prominence and width) at 1700+ K-NET and KiK-net strong-motion recordings stations.

This MATLAB code is for automatically picking peaks (frequency, amplitude, prominence and width) from HVSR curves.
