Variations in the crustal structure and strength of plate coupling along the Ryukyu subduction zone

Geoscience Letters, 2023
The Ryukyu trench-arc-back arc system is part of the subduction margins of the Philippine Sea plate. Previous studies have indicated that several geophysical and geological characteristics reveal significant variations (including convergent rate ...

Plate convergence measured by GPS across the Sundaland/Philippine Sea Plate deformed boundary: the Philippines and eastern Indonesia [PDF]

Geophysical Journal International, 1999
SUMMARY The western boundary of the Philippine Sea (PH) Plate in the Philippines and eastern Indonesia corresponds to a wide deformation zone that includes the stretched continental margin of Sundaland, the Philippine Mobile Belt (PMB), extending from Luzon to the Molucca Sea, and a mosaic of continental blocks around the PH/Australia/Sunda triple ...

Seismic Evidence of Ancient Westward Residual Slab Subduction Beneath Southern Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2015
The northeastern convergence of the Philippine Sea plate toward the Eurasian plate causes the major western Philippine Sea plate boundary to subduct toward the northwest or west directions. However, this phenomenon is not clearly observed along the plate

Enhanced arc magmatic productivity of the Western Pacific island arcs deduced from gravity-derived arc crustal growth rates

Frontiers in Earth Science, 2023
Island arcs are postulated as the juvenile components that contribute to the growth of continental crust. Growth rates of arc crusts were previously computed using crustal thicknesses derived from seismic data.

Preface to the Special Issue on "Geodynamics of Taiwan and the Philippines"

Terrestrial, Atmospheric and Oceanic Sciences, 2015
This special issue contains a collection of six papers dealing with the geology, geophysics, and tectonics of Taiwan and the Philippines. Most of these papers were presented at the fourth _ Earth Sciences International _ in Manila, Philippines, 8 - 9 ...

Tomographic image of crust and upper mantle off the Boso Peninsula using data from an ocean-bottom seismograph array

Earth, Planets and Space, 2017
We determined the three-dimensional structure of the crust and upper mantle off the Boso Peninsula, Japan, by analyzing seismograms recorded by ocean-bottom seismometers and land stations between 2011 and 2013. We employed seismic tomography to determine

Moment tensor inversion of the 2016 southeast offshore Mie earthquake in the Tonankai region using a three-dimensional velocity structure model: effects of the accretionary prism and subducting oceanic plate

Earth, Planets and Space, 2018
The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the interface of the Philippine Sea plate had been very low until this earthquake.

Mesozoic rock suites along western Philippines: Exposed proto-South China Sea fragments?

Journal of Asian Earth Sciences: X, 2020
An ancient oceanic crustal leading edge east of mainland Asia, the proto-South China Sea crust, must have existed during the Mesozoic based on tectonic reconstructions that accounted for the presence of subducted slabs in the lower mantle and the exposed

Seismic Structure of the Upper Mantle Beneath Eastern Asia From Full Waveform Seismic Tomography

Geochemistry, Geophysics, Geosystems, 2018
To better understand the subsurface behavior of subducting slabs and their relation to the tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large data set to determine a high‐resolution seismic model, FWEA18 (Full ...

Rotation of the Philippine Sea plate inferred from paleomagnetism of oriented cores taken with an ROV-based coring apparatus

Earth, Planets and Space, 2021
Reconstructing the history of Philippine Sea (PHS) plate motion is important for better understanding of the tectonics of the surrounding plates. It is generally considered that the PHS plate migrated northward since Eocene, but its rotation has not been
