The two large offshore earthquakes that occurred in Japan's eastern Fukushima region on
February 13, 2021, Mw 7.1 and March 17, 2022, Mw 7.4 are the two largest offshore …

This paper studies the effect of seawater depth on offshore earthquake motion
characteristics and seismic response of bridges. By analyzing the offshore seismic data …

Vulnerability of subsea high pressure/high temperature (HP/HT) pipelines to seismic actions
is studied numerically. Unlike most of the existing researches on buried or trenched …

This paper studies the dynamic response of a large diameter and thin-walled monopile,
embedded in a partially saturated porous seabed with saturation degrees larger than 95 …

Understanding offshore site amplification (AF) characteristics is crucial for marine
engineering. Thus far, the spectral ratio (SR) has been widely used to analyze offshore AF …

In this study, the characteristics of offshore ground motions related to elastic relative and
absolute input energy are investigated, and ground-motion prediction equations (GMPEs) …

This study proposes offshore ground motion models (GMMs) for Arias intensity and
cumulative absolute velocity by using the seafloor ground motion database in the Japan …

To distinguish offshore and onshore seismic ground motions, conventional analyses in
terms of peak ground acceleration (PGA) and earthquake response spectrum (ERS) have …

With the improvement of the world's largest seafloor observation network (S-net) and the
increase in the quantity and quality of records, the ergodic assumptions can be further …

The empirical correlation equation is developed to predict the correlation between two
intensity measures (IMs). Previous studies on empirical correlation equations have primarily …
