Long-term activity change in Very low-frequency earthquakes in the south Ryukyu Trench

2023
Very low-frequency earthquakes (VLFEs) occurred regularly along the south Ryukyu Trench. The activity was concentrated at the slab depth of 10-20 km along the trench axis. The VLFEs occurred every two to three months for a few days in a seismic swarm.

Assemblages of Harpacticoida (Crustacea: Copepoda) from the Ryukyu and Kuril Trenches, north-west Pacific Ocean

Journal of the Marine Biological Association of the United Kingdom, 2011
To examine the specific features of trench communities, spatial changes in the assemblages of harpacticoids were investigated at the family level around the Ryukyu Trench (the Ryukyu region) and Kuril Trench (the Kuril region). In the Ryukyu region, there were high average dissimilarities in the harpacticoid assemblages among the trench, trench slope ...

Very Low-Frequency Earthquakes and Earthquake Swarms in the Northern Ryukyu Trench

Slow earthquakes, distinct from regular earthquakes in their gradual release of seismic energy, play a key role in stress accumulation and release at subduction plate interfaces and have been proposed as potential precursors to large earthquakes. In the northern Ryukyu Trench, the Philippine Sea Plate subducts beneath the Eurasian Plate, and the region

Crustal structure across the middle Ryukyu trench obtained from ocean bottom seismographic data

Tectonophysics, 1996
Abstract In 1988 an extensive geophysical investigation was performed at the middle Ryukyu island arc, S. Japan. An aim of the investigation is to obtain a detailed crustal structure at the trench-arc-back-arc system by various geophysical surveys. In this paper we present fine crustal models obtained from ocean bottom seismographic (OBS) data along ...

Bathymetric patterns of meiofaunal abundance and biomass associated with the Kuril and Ryukyu trenches, western North Pacific Ocean

Deep Sea Research Part I: Oceanographic Research Papers, 2011
Abstract The abundance and biomass of metazoan meiofauna and their relationships with environmental factors [chloroplastic pigment equivalents (CPE) and sediment characteristics] were studied quantitatively around and within the Kuril Trench (560–7090 m) and the Ryukyu Trench (1290–7150 m), which are located in eutrophic and oligotrophic regions ...
