South Ilan Plain High-Resolution 3-D S-Wave Velocity from Ambient Noise Tomography
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.

Modern carbonate sedimentary facies on the outer shelf and slope around New Caledonia [PDF]
We investigated surface carbonate sediments at 33 sites on the outer shelf and slope around New Caledonia (163°-167°E, 20°-23°S), at water depths of 75-720m.

Melt Architecture Under East Asian Volcanoes Revealed by Anisotropic Tomography
Abstract Cenozoic volcanic rocks in East Asia are widespread across subduction zones, oceanic plates, and continental interiors. The generation of these volcanic materials is closely associated with partial melting of the upper mantle and the stagnation of the Pacific slab in the mantle transition zone.

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.

Effects of relative plate motion on the deep structure and penetration depth of slabs below the Izu-Bonin and Mariana island arcs [PDF]
An increasing number of seismological studies indicate that slabs of subducted lithosphere penetrate the Earth's lower mantle below some island arcs but are deflected, or, rather, laid down, in the transition zone below others.

Abstract Using dense seismic data sets, we present a new 3D velocity model of Taiwan that images a prominent mid‐crustal (∼20–30 km) high‐velocity body beneath west‐central Taiwan. The inclusion of high‐quality post‐2012 recordings from the Central Weather Administration Seismic Network (CWASN) ensures the elimination of uncorrectable timing errors. In

ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Eocene extensional tectonics in the Amakusa region, northern Ryukyu arc
AbstractPaleogene surface tectonics in Japan is not well understood because of the paucity of onshore Paleogene stratigraphic records except for those from accretionary complexes. Paralic Paleogene formations remaining in SW Japan are usually so thin that it is difficult to decipher the tectonics from them.

Complex shear wave splitting (SWS) patterns in subduction zones are often interpreted geodynamically as resulting from complex mantle flow; however, this may not always be necessary.

Anaglyphs produced using a digital elevation model (DEM) are effective to identify the characteristic tectono–geomorphic features. The objective of this study is to reinvestigate the tectonic geomorphology and to present novel tectonic maps of the ...
