Abstract Issues of predominant period of ground motion and derived underground velocity structure model are investigated in the coastal plains affected by the shallow soft sedimentary layer after the last ice age. It is found that two predominant per

Abstract On October 21, 2016, an earthquake with Japan Meteorological Agency (JMA) magnitude 6.6 hit the central part of Tottori Prefecture, Japan. This paper demonstrates two notable effects of the surface geology on strong ground motions due to the

The Editor-in-Chief is retracting this article (Hata et al. 2017) because an Investigation Committee established by Osaka University has found that data were fabricated by manipulation, and that theoretical calculation values were falsified to make t

In this research area, methodologies for prior predictions of potential hazards and real-time estimations of progressing hazards caused by earthquakes and volcanic eruptions are proved for disaster mitigation. The studies are based on the latest unde

We examined high-frequency spectral decay characteristics of ground motions for inland crustal earthquakes in Japan, which are important in strong ground motion predictions. We examined 105 earthquakes (Mw 3.3–7.1), including seven large earthquake
