Optimum parameter selection in offset-dependent predictive deconvolution: testing on multichannel marine seismic data
Predictive deconvolution is an effective way to suppress multiple reflections, especially short path multiples, in seismic data. However, the...

General Introduction
The study of fluid distribution along megathrust faults at subduction zones is important because such fluid controls the slip behavior of the...

Impact and Solutions of Seawater Heterogeneity on Wide-Angle Tomographic Inversion of Crustal Velocities in Deep Marine Environments—Numerical Studies
The seawater column is typically taken as a homogeneous velocity layer in wide-angle crustal seismic surveys in marine environments. However,...

The 2016 Mw 5.9 earthquake off the southeastern coast of Mie Prefecture as an indicator of preparatory processes of the next Nankai Trough megathrust earthquake
Megathrust earthquakes have occurred repeatedly at intervals of 100 to 150 years along the Nankai Trough, situated in the southwest of Japan. Given...

Application of Inverse Water-Layer Filter Method
Here, we address several issues regarding the application of an inverse water-layer filter (IWLF) method to observed data. Initially, we present a...

Moment tensor inversion of the 2016 southeast offshore Mie earthquake in the Tonankai region using a three-dimensional velocity structure model: effects of the accretionary prism and subducting oceanic plate
The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the...
