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 ...

Tectonics of earthquake swarms in the Tokara Gap of northern Ryukyu Arc based on marine geological and geophysical surveys

Scientific Reports
The 2025 Tokara seismic swarm, which began in late June, has been the largest documented sequence of earthquakes in the northern Ryukyu Arc. It has generated more than 2200 earthquakes, including episodes of strong ground-shaking at Akusekijima Island ...

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.

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
