Earth, Planets and Space, 2017 The Ryukyu (Nansei-Shoto) island arc-trench system, southwest of Japan, is formed by the subduction of the Philippine Sea (PHS) plate. Among the subduction zones surrounding the Japan Islands, the Ryukyu arc-trench system is unique in that its backarc ...

Low-frequency earthquakes along the Ryukyu Islands triggered by teleseismic earthquakes
Earth, Planets and Space, 2021 Tremors and low-frequency earthquakes (LFEs), which occur in the plate interface, can provide useful information about the state of aseismic stress transfer in mega-earthquake fault zones.

Earth, Planets and Space, 2018 Tectonic and volcanic structures of the northern Ryukyu arc are investigated on the basis of multichannel seismic (MCS) reflection data. The study area forms an active volcanic front in parallel to the non-volcanic island chain in the eastern margin of ...

Tectono-magmatic evolution of the Philippine Sea Plate: A review
Geosystems and Geoenvironment, 2022 The West Pacific Margin incorporates 75% of global marginal basins/back-arc basins. These basins and their adjacent trenches and island arcs constitute a huge trench-arc-basin system created by the interactions among three tectonic plates (the Pacific ...

Distribution of dissolved methane in seawater from the East China Sea to the Ryukyu forearc
Frontiers in Earth Science, 2023 Methane is a greenhouse gas, and the East China Sea acts as a source of emissions to the atmosphere. On the other hand, the distribution of methane concentration in the Ryukyu Arc shelf and forearc region has not been clarified.

Reappraisal of the Arc-Arc Collision in Taiwan
Terrestrial, Atmospheric and Oceanic Sciences, 2009 Al though it is evident that Taiwan has been formed by the collision of the west-facing Luzon arc with the Eurasian continental mar gin, there're main a lot of enigmas in this collision. The major ones are: (1) a trans form fault presently connecting the

Earth, Planets and Space, 2019 The Okinawa Trough, to the southwest of Kyusyu, Japan, is an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench system caused by the Philippine Sea plate subduction. Unlike other backarc basins around Japan, the Okinawa Trough, ~ 1000 km

Activated seismicity by strain rate change in the Yaeyama region, south Ryukyu
Earth, Planets and Space, 2018 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.

Ecology and Evolution, Volume 16, Issue 8, August 2026.Talipariti (Malvaceae) comprises two lineages with contrasting geographic ranges across Malesia: a pantropical sea hibiscus group and a Papuan group restricted to New Guinea and adjacent islands. Using phylogenomics, divergence‐time estimation, and quantitative biogeographical modelling applied to herbarium‐derived genomic data, we demonstrate that the
