...Nori Nakata Abstract Application of deconvolution interferometry to wavefields observed by KiK‐net, a strong‐motion recording network in Japan, is useful for estimating wave velocities and S ‐wave splitting in the near surface. At the location of the borehole accelerometer of each KiK‐net station...

...Adrien Oth; Stefano Parolai; Dino Bindi Abstract The wealth of accelerometric recordings collected by the K-NET and KiK-net networks in Japan since 1996 provides a unique opportunity to improve our understanding of many important seismological research questions. Subsets of these data have been...

... and hard to derive. In this study, we make use of the KiK‐net database in Japan that consists of surface and colocated downhole sensors. We select 175 sites where the bottom sensor is deployed at rock or hard‐rock conditions resulting in a database with many recordings at V S ≥ 1500 m / s . This allows us...

... to obtain a reference ground‐motion model, which consists of removing site effects from surface ground‐motion recordings. Laurendeau et al.

The method is validated through the comparison with empirical surface‐to‐borehole amplification curves observed in 144 selected KiK‐net vertical arrays in Japan. Using a frequency range of 0.1–50 Hz, we identified 36 and 83 sites with a good and partially good mutual fit...

In addition, the influence of earthquake magnitude on duration due to path effects is captured in the proposed relationships. Based on the relationships proposed in this study, we note that the duration of ground...
