recommendations! Published in 2017 at "Pure and Applied Geophysics"

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.margeo.2020.106225

Abstract: Abstract The 2011 Tohoku Tsunami induced sediment deposition of 334,000 m3 mainly in the basin and 9 m erosion at the tips of a breakwater and a groin in Oarai Port, Japan. The tsunami-induced bathymetry change was… 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: 10.1016/j.soildyn.2021.106606

Abstract: Abstract Propagation of long-period ground motion in sedimentary basins has been a subject of great interest among seismologists and engineers. Intense long-period ground motions consist primarily of surface waves that get trapped or generated locally… read more here.

DOI: 10.1017/s0373463317000595

Abstract: The current Korean national geodetic reference frame, KGD2002, refers to the fixed epoch at 2002·0 under the assumption that there is no crustal movement of the Korean peninsula. A discontinuity in the coordinates of the… read more here.

recommendations! Published in 2021 at "Earth and Space Science"

DOI: 10.1029/2020ea001217

Abstract: We investigate ionospheric disturbances using the total electron content (TEC) data obtained from the radio signals emitted from three satellites after the foreshock of the 2011 Tohoku Earthquake on March 9, 2011. Co‐seismic ionospheric disturbances… 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.

DOI: 10.1126/sciadv.adl4264

Abstract: Rock strength has long been linked to lithospheric deformation and seismicity. However, independent constraints on the related elastic heterogeneity are missing, yet could provide key information for solid Earth dynamics. Using coseismic Global Navigation Satellite… read more here.

DOI: 10.1190/int-2024-0162.1

Abstract: The ability to predict earthquakes is invaluable, especially in high-risk seismic zones, yet precise predictions remain elusive. One potential reason is the limited integration of statistical approaches in earthquake research. In this study, I employed… read more here.
