Risk Factor Detection and Landslide Susceptibility Mapping Using Geo-Detector and Random Forest Models: The 2018 Hokkaido Eastern Iburi Earthquake

open access: yesRemote Sensing, 2021
Landslide susceptibility mapping is an effective approach for landslide risk prevention and assessments. The occurrence of slope instability is highly correlated with intrinsic variables that contribute to the occurrence of landslides, such as geology ...

RETRACTED ARTICLE: Estimation of the source process and forward simulation of long-period ground motion of the 2018 Hokkaido Eastern Iburi, Japan, earthquake

open access: yesEarth, Planets and Space, 2019
In this study, we investigate the source rupture process of the 2018 Hokkaido Eastern Iburi earthquake in Japan (M JMA 6.7) and how the ground motion can be reproduced using available source and velocity models.
