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.

  1. We have been discussing the validity of using the horizontal-to-vertical spectral ratios (HVRs) as a substitute for S-wave amplifications after Nakamura first proposed the idea in 1989. So far a formula for HV...

  2. Under the diffuse field approximation, the full-wave (FW) microtremor H/V spectral ratio (H/V) is modeled as the square root of the ratio of the sum of imaginary parts of the Green’s function of the horizontal co...

  3. The aim of this paper is to investigate the ability of various site-condition proxies (SCPs) to reduce ground-motion aleatory variability and evaluate how SCPs capture nonlinearity site effects. The SCPs used ...

  4. Although rotational seismology has progressed in recent decades, the links between rotational ground motion and site soil conditions are poorly documented. New experiments were performed on Kefalonia Island (G...
