DOI: 10.1007/s00024-017-1558-2
Abstract: Mechanisms are suggested that could explain anomalously high PGAs (peak ground accelerations) exceeding 1 g recorded during the 2011 Tohoku earthquake (Mw = 9.0). In my previous research, I studied soil behavior during the Tohoku earthquake based on… read more here.

DOI: 10.1016/j.sedgeo.2020.105791
Abstract: Abstract Deep-sea turbidite deposits are useful tools for submarine paleoseismology. It is fundamental to understand what kind of disturbance occurred owing to the earthquake and which event-induced deposits were formed in a particular area. The… read more here.

DOI: 10.1038/s41467-020-14745-8
Abstract: The mechanism and rupture process of the giant 2011 Tohoku-oki earthquake (Mw 9.0) are still poorly understood due to lack of permanent near-field observations. Using seismic arrival times recorded by dense seismograph networks on land… read more here.

DOI: 10.1038/s41598-021-87152-8
Abstract: Tsunamis are generally considered to disturb the seafloor, rework surface sediments, and change seafloor environments. However, the response of the seafloor to such extreme wave events has not been fully elucidated. Herein, we compare the… read more here.
