Prediction of Complex Observed Shear Wave Splitting Patterns at Ryukyu Subduction Zone Using a Strong Intra‐Slab Anisotropy Model

Geophysical Research Letters
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.

Topographic Anaglyphs from Detailed Digital Elevation Models Covering Inland and Seafloor for the Tectonic Geomorphology Studies in and around Yoron Island, Ryukyu Arc, Japan

Geosciences, 2018
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 ...

Characteristic Earthquake Sequences near Miyakojima Island, Ryukyu Arc, Japan

Zisin (Journal of the Seismological Society of Japan. 2nd ser.), 2010
We found eight M 5.1 characteristic earthquakes regularly occurring since 1966 on the plate boundary between the Eurasian plate and the Philippine Sea plate near Miyakojima Island, the Ryukyu Arc, Japan. The quake recurrence interval was 5.89 years in average, and the standard deviation was only 0.73 years.

Eocene extensional tectonics in the Amakusa region, northern Ryukyu arc

Island 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.

New Magnetic Anomaly Map of the East Asia with Some Preliminary Tectonic Interpretations

Terrestrial, Atmospheric and Oceanic Sciences, 2015
Magnetic data provides basic information for geological and geophysical interpretation. In this study we compile recently collected (57 cruises survey) and old (published and open access) magnetic data.

Crustal density structure investigation of the East China Sea and adjacent regions using wavenumber domain 3D density imaging method

Earth, Planets and Space
The East China Sea, situated at the intersection of the Eurasian, Philippine Sea, and Pacific plates, is characterized by complex geology influenced by tectonic phenomena such as plate movements, volcanism, faults, and uplifts.

Geological and Geographical Characteristics of Limestone and Karst Landforms in Japan: Insights from Akiyoshidai, Seiyo (Shikoku), and Okinoerabu Island

Geosciences
Limestone in Japan exhibits distinct distribution patterns and associated lithologies compared to limestone found in most other parts of the world. These differences reflect contrasting depositional settings and formation processes. While the majority of

Imaging of Arc-Arc Collision in the Ryukyu Forearc Region Offshore Hualien From TAICRUST OBS Line 16

Terrestrial, Atmospheric and Oceanic Sciences, 1998
A velocity model constructed using ocean bottom seismometer(OBS)data collected along TAICRUST Line 14 indicates that the Ryukyu Arcbasement(velocity＞～5 km/s)extends beneath the Nanao forearc basin to adepth of 18 to 20 km.Furthermore,our velocity model indicates that theRyukyu Arc basement extends west to at least 122°E,near the west end ofline 14 ...
