Paleoseismic trenching on slip-partitioned surface ruptures associated with the 2016 Kumamoto earthquake Surface ruptures appear over a wide area in addition to the primary fault during a Large earthquake like the 2016 Kumamoto earthquake. Although the displacement of such distributed surface ruptures is...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy an...

Constraining a high-slip offshore fault area during the 2024 Noto Peninsula earthquake using tsunami inundation data and numerical simulations The 2024 Noto Peninsula earthquake (Mw 7.5) caused significant tsunami inundation along the northeastern coast of the Noto Peninsula in Ishikawa Prefecture, Japan. To investigate the offshore slip ...
