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.

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 ...

Facies control on provenance shift during the early Cambrian transgression in Korea: Detrital zircon and geochemical evidence

Sedimentology, Volume 73, Issue 2, Page 418-440, February 2026.
ABSTRACT The early Cambrian transgression that flooded continental margins worldwide produced extensive sedimentary records that archive valuable information about palaeogeography and basin dynamics. This study integrates detrital zircon U–Pb geochronology and wholerock geochemistry from the Myeonsan and Myobong formations of the basal Taebaek Group ...

Complex evolution and biogeographic history of moss‐inhabiting flea beetles from the Taiwan‐Ryukyu Island Arc (Coleoptera: Chrysomelidae: Alticini)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Extensive radiation of moss‐inhabiting flea beetles in Taiwan and Japan: The Ivalia uenoi complex displays high species diversity closely related to Japanese species. Complex biogeography revealed by phylogenomics: ddRAD data uncovered a history shaped by Miocene vicariance and Pliocene dispersal from Taiwan across the Taiwan‐Ryukyu archipelago ...

Cold Seep Communities in the Sea of Japan Are Species‐Poor and Dominated by a New Species of Provannid Snail

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Sea of Japan is a semi‐enclosed marginal sea in the northwestern Pacific whose bathyal communities exhibit a depauperate species diversity due to anoxic events during the last glacial maximum. Cold seeps associated with chemosynthetic ecosystems were discovered in this region over three decades ago, yet their fauna have not been characterised. Here,

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.

A Review of the Widespread Indo‐West Pacific Ghost Crab, Ocypode ceratophthalmus (Pallas, 1772) (Crustacea: Decapoda: Ocypodidae) Complex, With the Description of a New Species

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The widespread Indo‐West Pacific ghost crab, Ocypode ceratophthalmus (Pallas, 1772) is found to be a species‐complex containing three distinct species. An Indian Ocean form, O. celadon sp. nov. occurs along the shores of East Africa, thence becoming an insular species spreading eastwards as far as Christmas Island.

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.

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.
