High-density surveys conducted to reveal active deformations of the upper forearc slope along the Ryukyu Trench, western Pacific, Japan

Progress in Earth and Planetary Science, 2018
In this study, which was conducted to investigate present-day geological deformations occurring off the central Ryukyu Arc along the Ryukyu Trench (Okinawa-jima) in the vicinity of Japan, we obtained and examined dense, high-resolution, 2D grid (high ...

Variations in seismic velocity distribution along the Ryukyu (Nansei-Shoto) Trench subduction zone at the northwestern end of the Philippine Sea plate

Earth, Planets and Space, 2017
The Ryukyu (Nansei-Shoto) island arc-trench system, southwest of Japan, is formed by the subduction of the Philippine Sea (PHS) plate. Among the subduction zones surrounding the Japan Islands, the Ryukyu arc-trench system is unique in that its backarc ...

Variations in the crustal structure and strength of plate coupling along the Ryukyu subduction zone

Geoscience Letters, 2023
The Ryukyu trench-arc-back arc system is part of the subduction margins of the Philippine Sea plate. Previous studies have indicated that several geophysical and geological characteristics reveal significant variations (including convergent rate ...

Origins of sediments and fluids in submarine mud volcanoes off Tanegashima Island, northern Ryukyu Trench, Japan

Frontiers in Earth Science, 2023
Mud volcanoes are topographic features through which over-pressurized sediments are intruded upward and erupted, transporting fluids and sediments from the deep subsurface to the surface/seafloor. To understand material and biogeochemical cycling through

Modeling the impact of the trench depth on the gate-drain capacitance in power MOSFETs [PDF]

, 2011
Trench depth is important in low-voltage trench MOSFETs because it affects the switching losses through the gate-drain capacitance (C(GD)).

Low-frequency earthquakes along the Ryukyu Islands triggered by teleseismic earthquakes

Earth, Planets and Space, 2021
Tremors and low-frequency earthquakes (LFEs), which occur in the plate interface, can provide useful information about the state of aseismic stress transfer in mega-earthquake fault zones.
