Activated seismicity by strain rate change in the Yaeyama region, south Ryukyu

open access: yesEarth, Planets and Space, 2018
We evaluated the long-term strain rate by using continuous global navigation satellite system data of GEONET and compared it with seismicity activation between 1996 and 2017 near Iriomote Island, south Ryukyu arc.

A hypothesis of the obliquely subducted Gagua Ridge below Nanao Basin based on uplifted structures in Ryukyu forearc

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2023
At the southernmost part of the Ryukyu subduction zone, six long-offset multi-channel seismic profiles were collected across three forearc basins and the southern Ryukyu accretionary prism during the TAIGER experiment in 2009 and the TAICRUST project in ...

Opposite subduction polarity in adjacent plate segments [PDF]

open access: yes, 2018
Active and fossil subduction systems consisting of two adjacent plates with opposite retreating directions occur in several areas on Earth, as the Mediterranean or Western Pacific.

Seismic structure of the northern end of the Ryukyu Trench subduction zone, southeast of Kyushu, Japan [PDF]

open access: yesEarth, Planets and Space, 2009
Abstract P-wave velocity models related to the Philippine Sea plate subduction have been obtained from seismic explorations at the northern end of the Nansei-Shoto (Ryukyu) Trench. Both multi-channel seismic reflection and ocean bottom seismographic records provide clear images of the rough seafloor topography and irregular P ...

Sub‐slab anisotropy beneath the Sumatra and circum‐Pacific subduction zones from source‐side shear wave splitting observations

open access: yesGeochemistry, Geophysics, Geosystems, 2014
Understanding the dynamics of subduction is critical to our overall understanding of plate tectonics and the solid Earth system. Observations of seismic anisotropy can yield constraints on deformation patterns in the mantle surrounding subducting slabs ...

Response of the mantle to flat slab evolution: Insights from local splitting beneath Peru [PDF]

open access: yes, 2014
The dynamics of flat subduction, particularly the interaction between a flat slab and the overriding plate, are poorly understood. Here we study the (seismically) anisotropic properties and deformational regime of the mantle directly above the Peruvian ...

The Scholar Imprisoned: Young‐Bok Shin's Decolonial Thought Against (Sub) Imperialisms in East Asia

open access: yesSociological Forum, EarlyView.
ABSTRACT This article reads Young‐Bok Shin (1941–2016) as a decolonial thinker who theorized transformative worldmaking from the standpoint of the oppressed, rooted in the historical experiences of East Asia. Against the (sub)imperial “logic of sameness” that structures colonial modernity in his social world, Shin advances gongbu (studying) as a ...

Effects of relative plate motion on the deep structure and penetration depth of slabs below the Izu-Bonin and Mariana island arcs [PDF]

open access: yes, 1993
An increasing number of seismological studies indicate that slabs of subducted lithosphere penetrate the Earth's lower mantle below some island arcs but are deflected, or, rather, laid down, in the transition zone below others.

The process of overcoming challenges faced by midwives providing perinatal mental health care in obstetric facilities in Okinawa, Japan: A qualitative study

open access: yesJapan Journal of Nursing Science, Volume 23, Issue 3, July 2026.
Abstract Aim This study aimed to clarify how midwives overcome challenges in providing perinatal mental health (PMH) care in clinical settings and to inform feasible, context‐sensitive educational support. Methods We used an interpretivist–constructivist qualitative design with a sequential two‐stage approach.

Slab horizontal subduction and slab tearing beneath East Asia [PDF]

open access: yes, 2019
The present‐day architecture of subducted slabs in the mantle as inferred from seismic tomography is a record of plate tectonics through geological time. The unusually large slab that lies nearly horizontally above the 660‐km mantle discontinuity beneath
