Effects of Surface Geology on Seismic Motion
Site amplification factors at period ranges of 0.1-0.2, 0.2-0.3, 0.3-0.5, 0.5-1, 1-2, and 2-10 s were determined for 27 stations of KiKnet and K-NET in and around the source area of the 2008 Iwate-Miyagi Nairiku earthquake. The ratio of the geometric mean values of the two maximum horizontal amplitudes of acceleration and velocity at the uphole to that at the downhole is considered as the ampli...

The site response transfer functions using 1D layered velocity models based on microtremor array exploration in the Niigata area, Japan, were examined whether it would be possible to explain the estimated high-frequency site responses using observed earthquake records or not. Our results showed the site response transfer functions were relatively larger in the frequency over about 3 or 6 Hz tha...

A long-term experiment was planned and performed to assess the contemporary ability to predict the effects of near surface geology on strong ground motion. The experiment was established at an alluvial valley called Turkey Flat, about 5 km from the eventual M6.

This study presents observations of nonlinear soil behavior evidence at several KiK-net sites. First, we compare the site responses performed with 1) the recordings from the aftershocks and 2) the recordings from the main event of the 2011 Tohoku earthquake at four sites. Then, to understand the influence of soil parameters on nonlinear effects, we extend the results to the whole network. We co...

We introduce a new conserved quantity, Normalized Energy Density (NED), alternative to the conventional definition of energy for a layered structure in a 2D SH problem. NED is defined by the average of power of a half transfer function multiplied by the impedance, and the conservation across the material interface is analytically proved for a two-layered case. For three, four, and tenlayered ca...
