In the past few decades, the study on site effects of seismic ground motions induced by surface geology and subsurface structures (Effects of Surface Geology on seismic motion, ESG) are progressing for understanding strong ground motion characteristics during disastrous earthquakes and for predicting strong ground motions for future events, with increasing numbers of strong motion data and computer powers. There are still huge earthquake disasters occurring all over the world and the researches for quantification of ESG should be emphasized for earthquake disaster mitigations because of their significant influence on strong motions. In this coming summer, the 5th International Conference on Effects of Surface Geology on Seismic Motions (ESG5) will be held in Taipei, Taiwan and there are about 140 papers from over 20 countries to be presented. On this occasion, we would like to propose to publish special issue or issues for recent progress of study on ESG in EPS journal to share the present status on this study area. We are expecting that many of the authors who contribute to ESG5 will submit their papers to this EPS special issue(s) but we would not exclude any authors who do not participate in ESG5 but write relevant papers. We believe that this special issue(s) will attract broad spectrum of readers and contribute to stimulate discussion on new paradigms of future ESG studies and seismology in general.

    Assessment of nonlinear site response at ocean bottom seismograph sites based on S-wave horizontal-to-vertical spectral ratios: a study at the Sagami Bay area K-NET sites in Japan

    We analyzed S-wave horizontal-to-vertical (S-H/V) spectral ratios at six ocean bottom seismograph (OBS) sites of K-NET located in the Sagami Bay area of Japan for nonlinear site responses. The degree of nonlin...
