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.

Assessing relational values of sacred landscapes through text mining of folktales: Insights from the Ryukyu Islands, Japan

People and Nature, Volume 8, Issue 7, Page 2383-2392, July 2026.
Abstract Assessing relational values of nature through its cultural and spiritual significance is crucial for effective nature conservation. Folktales offer insights into traditional relationships between people and nature, and text mining is a powerful tool for extracting information from textual datasets.

High‐Rate GNSS Analysis of the Onset, Growth, and Termination of Slow Slip Events and Their Along‐Dip Variability Offshore the Boso Peninsula, Japan (2011–2024)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Recurring slow slip events (SSEs) with moment magnitudes in the mid‐6 range have occurred every few years since the 1990s offshore the Boso Peninsula, Japan. These events occur near the source area of ∼M8 megathrust earthquakes beneath the Tokyo metropolitan area and are accompanied by earthquake swarms.

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.

Origin, Tectonic Processes, and Metasomatism of Serpentinite in the Shimanto Accretionary Complex, SW Japan: Possible Diapiric Intrusion of Serpentinized Oceanic Lithosphere

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Serpentinite plays a major role in the geodynamics of subduction zones. However, the processes by which serpentinite is incorporated into accretionary complexes, and the extent to which it interacts chemically and physically with accretionary lithologies, remain unclear.

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.

A Plate‐Based Model for Reconciling Geodetic and Geologic Vertical Deformation Across Taiwan

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Reconciling geodetic and geologic deformation remains a fundamental challenge in tectonic studies of active orogens. Elastic rebound theory posits that present‐day deformation differs from deformation recorded over time scales longer than the earthquake cycle because locked faults store and release strain.

Tectonic geomorphology of the Ryukyu Trench-Arc-Backarc System: geological-geophysical exploration and mapping

Chinese Science Bulletin, 2004
Based on an analysis of full-cover multi-beam bathymetric data, seismic and sub-bottom profiling data, and other geological-geophysical data sets, the geomorphologic features of the Ryukyu trench-arc-backarc (T-A-BA) system are delineated, and a geomorphologic map of the system is compiled.

Fault model of the 1771 Yaeyama earthquake along the Ryukyu Trench estimated from the devastating tsunami [PDF]

Geophysical Research Letters, 2009
The 24 April 1771 Yaeyama earthquake generated a large tsunami with a maximum runup of 30 m, causing significant damage in south Ryukyu, Japan, despite the weak ground shaking. Previously proposed mechanisms of the tsunami include intraplate faulting or submarine landslide in the forearc slope. In this study, I estimate the fault parameters of the 1771
