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.

Geodetic Evidence of Shallow Slow‐Slip Phenomena Beneath the Southern Ryukyu Forearc

Geophysical Research Letters
While slow slip events (SSEs) are recognized as a ubiquitous phenomenon in subduction zones, accurately tracking the spatiotemporal distribution of shallow SSEs remains challenging.

New source model for the 1771 Meiwa tsunami along the southern Ryukyu Trench inferred from high-resolution tsunami calculation

Progress in Earth and Planetary Science
The 1771 Meiwa tsunami which struck the southern Ryukyu Islands (Sakishima Islands) had greater than 22 m run-up height, leaving about 12,000 casualties in its wake.

South Ilan Plain High-Resolution 3-D S-Wave Velocity from Ambient Noise Tomography

Terrestrial, Atmospheric and Oceanic Sciences, 2016
The Ilan Plain in northeastern Taiwan is located at a pivotal point where the Ryukyu trench subduction zone, the northern Taiwan crustal stretching zone, and the ongoing arc-continent collision zone converge.

Millennial paleotsunami history at Minna Island, southern Ryukyu Islands, Japan

Progress in Earth and Planetary Science, 2020
Huge tsunami waves have repeatedly bombarded the southern end of the Ryukyu Islands (Miyako and Yaeyama Islands, southwestern Japan) at several-hundred-year intervals.

Prediction of Complex Observed Shear Wave Splitting Patterns at Ryukyu Subduction Zone Using a Strong Intra‐Slab Anisotropy Model

Geophysical Research Letters
Complex shear wave splitting (SWS) patterns in subduction zones are often interpreted geodynamically as resulting from complex mantle flow; however, this may not always be necessary.

The Sub-Crustal Stress Field in the Taiwan Region

Terrestrial, Atmospheric and Oceanic Sciences, 2015
We investigate the sub-crustal stress in the Taiwan region. A tectonic configuration in this region is dominated by a collision between the Philippine oceanic plate and the Eurasian continental margin.

Atribacteria from the Subseafloor Sedimentary Biosphere Disperse to the Hydrosphere through Submarine Mud Volcanoes

Frontiers in Microbiology, 2017
Submarine mud volcanoes (SMVs) are formed by muddy sediments and breccias extruded to the seafloor from a source in the deep subseafloor and are characterized by the discharge of methane and other hydrocarbon gasses and deep-sourced fluids into the ...

Spatiotemporal variability and tectonic implications of very low-frequency earthquakes in the southwestern Ryukyu Trench

Earth, Planets and Space
This study focuses on very low-frequency earthquakes (VLFEs) occurring in the southwestern Ryukyu Trench and investigates their long-term activity as well as their relationship with regional seismicity and tectonic features.

New Magnetic Anomaly Map of the East Asia with Some Preliminary Tectonic Interpretations

Terrestrial, Atmospheric and Oceanic Sciences, 2015
Magnetic data provides basic information for geological and geophysical interpretation. In this study we compile recently collected (57 cruises survey) and old (published and open access) magnetic data.
