Back-arc opening and the mode of subduction [PDF]
Trench-arc systems (subduction zones) can be classified into two types depending on whether or not actively opening back-arc basins are associated with them.

On the origin of the North Pacific arcs [PDF]
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Comparative Population Genetics of Two Alvinocaridid Shrimp Species in Chemosynthetic Ecosystems of the Western Pacific. [PDF]
Little is known about the population divergence and gene flow of deep‐sea animals living in disjunct hydrothermal vents and cold seep habitats. Taking advantage of samples collected from multiple cruises across a huge distance of >5000 km, we revealed the differential population divergence pattern and gene flow in two congeneric species of shrimps ...

Activated seismicity by strain rate change in the Yaeyama region, south Ryukyu
We evaluated the long-term strain rate by using continuous global navigation satellite system data of GEONET and compared it with seismicity activation between 1996 and 2017 near Iriomote Island, south Ryukyu arc.

Investigating the kinematics of mountain building in Taiwan from the spatiotemporal evolution of the foreland basin and western foothills [PDF]
The Taiwanese range has resulted from the collision between the Luzon volcanic arc and the Chinese continental margin, which started about 6.5 Myr ago in the north, and has since propagated southward.

Millennial slip rate of the Longitudinal Valley fault from river terraces: Implications for convergence across the active suture of eastern Taiwan [PDF]
The Longitudinal Valley fault is a key element in the active tectonics of Taiwan. It is the principal structure accommodating convergence across one of the two active sutures of the Taiwan orogeny.

Tectonics of the Ryukyu Island Arc
The geological and structural contrast between the north and central Ryukyus and the south Ryukyus has been significant since the Late Mesozoic. The difference seems to correspond to that of the nature of the Philippine Sea floor facing the Ryukyus, i.e. the Daito Ridges and Amami plateau to the north and deeper basin to the south.

Missing western half of the Pacific Plate: Geochemical nature of the Izanagi-Pacific Ridge interaction with a stationary boundary between the Indian and Pacific mantles [PDF]
The source mantle of the basaltic ocean crust on the western half of the Pacific Plate was examined using Pb–Nd–Hf isotopes. The results showed that the subducted Izanagi–Pacific Ridge (IPR) formed from both Pacific (180–∼80 Ma) and Indian (∼80–70 Ma ...

Triassic 40Ar/39Ar ages from the Sakaigawa unit, Kii Peninsula, Japan: implications for possible merger of the Central Asian Orogenic Belt with large-scale tectonic systems of the East Asian margin [PDF]
International audienceThe 218.4 ± 0.4, 228.8 ± 0.9 and 231.9 ± 0.7 Ma 40Ar/39Ar laser probe pseudo-plateau ages (2σ; 49–63% 39Ar-release) of very low-grade meta-pelitic whole-rocks from the Sakaigawa unit date high-P/T metamorphism.

Upper mantle velocity structure in the Ryukyu and Taiwan-Luzon arcs.
Upper mantle velocity structure in the Ryukyu and Taiwan-Luzon Island arc regions of the northwest Pacific has been determined to a depth of about 255 km from the analysis of P and S wave travel times data of 106 earthquakes with focal depths varying from 35 to 255 km.
