Stress-driven faulting with weak overpressure in the Tokara Islands, Ryukyu Arc: implications for fault reactivation under backarc extension

Earth, Planets and Space
We investigate the shallow stress regime and pore fluid pressure conditions in the Tokara Islands region of the northern Ryukyu Arc, where active seismicity occurs in a complex tectonic setting characterized by backarc extension.

Punctuated growth of an accretionary prism and the onset of a seismogenic megathrust in the Nankai Trough

Progress in Earth and Planetary Science, 2018
Ocean drilling in the Nankai Trough forearc suggests a new scenario for the evolution of the Nankai subduction zone. Continuous subduction since the Late Cretaceous has been a common tectonic scenario, although the plate subduction was transferred from ...

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

Large-scale slope failure and active erosion occurring in the southwest Ryukyu fore-arc area [PDF]

Natural Hazards and Earth System Sciences, 2001
The southwestern Ryukyu area east of Taiwan Island is an arcuate boundary between Philippine Sea Plate and Eurasian Plate. The topographic features in the area are characterised by (1) a large-scale amphitheatre off Ishigaki Island, just on the ...

Chemical Geodynamics of Granitoid Magmatism During a Pacific‐Philippine Sea Plate Transition in Southwest Japan

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma‐source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene ...

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal deformation. Using dense P‐ and S‐wave spectral amplitude data recorded by SALUTE and a quality

Stress Transfer From Slow Slip Events to Earthquake Swarms as a Cycle in the Southernmost Ryukyu Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Microbial distribution on sandstone with honeycomb weathering along rocky coasts in a subtropical environment

Terrestrial, Atmospheric and Oceanic Sciences
Weathering processes occur on terrestrial surfaces in combination with atmospheric and oceanic environments. Salt weathering often results in the formation of a honeycomb structure (tafoni) and a concave microrelief.

Spatial and temporal distribution of low frequency volcanic earthquakes in the southern Okinawa Trough back-arc basin

Terrestrial, Atmospheric and Oceanic Sciences, 2019
Located to the south of East China Sea, the Southern Okinawa Trough (SOT) is a back-arc basin, which belongs to the Ryukyu subduction system. SOT is characterized by an active normal faulting system and numerous volcanic outcrops, which could have marine

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.
