The Kiban-Kyoshin network database is an important resource for ground motion (GM) studies. The processing of these records is a necessary first step to enable their use in engineering applications. In this manuscript we present a step-by-step automated protocol used to systematically process about 157,000 KiK-net strong ground motion records.
The automated protocol includes the selection of corner frequencies for band-pass filtering. In addition, a comprehensive set of metadata was compiled for each record. As a part of the metadata collection, two algorithms were used to identify dependent and independent earthquakes. Earthquakes are also classified into active crustal or subduction type events; most of the GM records correspond to subduction type earthquakes. A flatfile with all the metadata and the spectral acceleration of the processed records is given.
We also present the pseudo-spectral accelerations for the KiK-net strong ground motion database.
