Seismic structure of rifting in the Okinawa Trough, an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench system

Earth, Planets and Space, 2019
The Okinawa Trough, to the southwest of Kyusyu, Japan, is an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench system caused by the Philippine Sea plate subduction. Unlike other backarc basins around Japan, the Okinawa Trough, ~ 1000 km

Quantitative Inferior T‐Wave Inversion as a Marker of High Pulmonary Vascular Resistance and All‐Cause Mortality in Patients Evaluated for Pulmonary Hypertension

Pulmonary Circulation, Volume 16, Issue 4, October 2026.
ABSTRACT Right heart catheterization defines pulmonary hypertension (PH) hemodynamics, but simple markers of pulmonary vascular load remain useful. Inferior‐lead T‐wave inversion (TWI) is seen in right ventricular pressure overload; its association with pulmonary vascular resistance (PVR) and prognosis is uncertain.

Analysis of a Permanent Downwelling Zone in the East China Sea Using the Hybrid Coordinate Ocean Model (HYCOM)

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Vertical motion in the East China Sea is examined using a 1/12.5° regional HYbrid Coordinate Ocean Model simulation from 2018 to 2022. Here we present an area of persistent downwelling ∼200 km East‐Northeast of Taiwan where the Kuroshio flows along the continental slope.

Assemblages of Harpacticoida (Crustacea: Copepoda) from the Ryukyu and Kuril Trenches, north-west Pacific Ocean

, 2011
To examine the specific features of trench communities, spatial changes in the assemblages of harpacticoids were investigated at the family level around the Ryukyu Trench (the Ryukyu region) and Kuril Trench (the Kuril region).

An Experimental Multi-disciplinary observatory (VENUS) at the Ryukyu Trench using the Guam-Okinawa Geophysical Submarine Cable

Annals of Geophysics, 2006
A multidisciplinary Ocean Bottom Observatory (MDOBO) was installed on VENUS (Versatile Eco-monitoring Network by Undersea-cable System) a depth of 2,170 meters on the slope of the Ryukyu Trench.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Thermal and Structural Signatures Associated With Subducted Seamounts in Hyuga‐nada and Off Cape Muroto, Southwest Japan

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present heat flow estimates beneath the forearc slopes off Hyuga‐nada and Cape Muroto in the Nankai Trough, where the Philippine Sea plate subducts beneath the southwestern Japan. Using seismic reflection data, we identified Bottom Simulating Reflectors and derived heat flow ranging from 20 to >140 mW/m2.

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Shear wave splitting from local events beneath the Ryukyu arc : Trench-parallel anisotropy in the mantle wedge [PDF]

, 2006
We present shear wave splitting measurements from local slab earthquakes at eight seismic stations of the Japanese F-net array located in the Ryukyu arc.
