Slab Pull Drives IBM Trench Advance Despite the Weakened Philippine Sea Plate
Geophysical Research Letters, 2023 The mechanism behind the significant Izu‐Bonin‐Mariana (IBM) trench advance is still controversial. We conduct slab subduction numerical models that reproduce the spatio‐temporal tectonic evolution of the Philippine Sea region to investigate whether slab

Frontiers in Earth Science, 2021 Long-term seafloor geodetic measurements are important for constraining submarine crustal deformation near plate boundaries. Here we present an integrated analysis of a decade of GNSS/acoustic data collected at a site 60 km to the east of northeast ...

Earth, Planets and Space, 2022 Here, I investigated whether the b-value in the rift-axis of the Okinawa Trough, a back-arc basin, is low. The cause of the low b-value in the rift-axis of the Okinawa Trough had previously been interpreted as increased stress by dyke intrusion. However,

Progress in Earth and Planetary Science, 2018 In this study, which was conducted to investigate present-day geological deformations occurring off the central Ryukyu Arc along the Ryukyu Trench (Okinawa-jima) in the vicinity of Japan, we obtained and examined dense, high-resolution, 2D grid (high ...

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.

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 ...

Extension in the southern Ryukyu arc (Japan): Link with oblique subduction and back arc rifting [PDF]
Tectonics, 1999 Compilation of earthquake focal mechanisms, morphological analysis, and examination of mesofractures help to clarify the Cenozoic and recent stress history in the southern Ryukyu arc between the Ryukyu trench and the southern Okinawa Trough. (1) An older, pre‐Miocene, intermediate‐type stress field (vertical stress component σv = σ2) is attested by ...

Variation in mitochondrial DNA of Vietnamese pigs: Relationships with Asian domestic pigs and Ryukyu wild boars [PDF]
, 2002 Mitochondrial DNA (mtDNA) sequences (574 bp) of 30 Vietnamese pigs (large and small) were examined and compared with those of 61 haplotypes from wild boars and domestic pigs from various locations in Asia.
