Tidal sensitivity of shallow very low frequency earthquakes in the Ryukyu Trench

Journal of Geophysical Research: Solid Earth, 2017
AbstractWe show that the activity between 2002 and 2014 of shallow very low frequency earthquakes (VLFEs), which occur in shallow subduction zones of the Ryukyu Trench, responds to ocean and Earth tides. Tidal sensitivity is highest in the central portion of the Ryukyu Trench and lowest in the southwest. The lag of peak VLFE activation behind the peaks

The Ryukyu Trench may function as a “depocenter” for anthropogenic marine litter

Journal of Oceanography, 2016
While concern over anthropogenic marine litter around coastlines is increasing worldwide, information on this litter in trenches on the seafloor is very sparse. We investigated the amount of marine litter on the deep-sea bottom around the Ryukyu Islands in the Northwest Pacific, based on trawl samples.

Source of high tsunamis along the southernmost Ryukyu trench inferred from tsunami stratigraphy

Tectonophysics, 2018
Abstract Four paleotsunamis deposits are exposed in a trench on the coastal lowland north of the southern Ryukyu subduction zone trench. Radiocarbon ages on coral and bivalve shells show that the four deposits record tsunamis date from the last 2000 yrs., including a historical tsunami with a maximum run-up of 30 m in 1771, for an average recurrence ...

Trench‐parallel flow in the southern Ryukyu subduction system: Effects of progressive rifting of the overriding plate

Journal of Geophysical Research: Solid Earth, 2013
AbstractThe Okinawa trough in the Ryukyu subduction system is one of a few actively extending back arc basins within the continental lithosphere. Recent shear‐wave splitting measurements show variable fast directions along the trough suggesting a complex three‐dimensional mantle flow field.

Bathymetric patterns of α and β diversity of harpacticoid copepods at the genus level around the Ryukyu Trench, and turnover diversity between trenches around Japan

Progress in Oceanography, 2014
Abstract The diversity of harpacticoid copepods was investigated around the Ryukyu Trench (430–7150 m), which lies below an oligotrophic subtropical ocean. The α diversity, which is based on the number of genera and Shannon diversity decreased with increasing water depth.

Morpho-sedimentary features and sediment dispersal systems of the southwest end of the Ryukyu Trench: a source-to-sink approach

Geo-Marine Letters, 2017
The southwestern Ryukyu Trench near Taiwan is an ideal place for source-to-sink studies because of the short sediment transport route between the terrestrial sediment source in Taiwan and the marine sink in the Ryukyu Trench. Bathymetric and seismic reflection data and core samples from the area around the southwestern Ryukyu Trench were used to ...

Late Quarternary paleoceanographic record from the middle Ryukyu Trench slope, northwest Pacific

Marine Micropaleontology, 1991
Abstract A piston core, KT84-14·P1, from the middle Ryukyu Trench slope, contains many paleoceanographic indicators of the past ca. 150,000 years. The age-assignment is based on such criteria as the abundance change between Gephyrocapsa ericsoni and Emiliania huxleyi , the datum of which is here substantiated by tephrochronology of an ash bed and ...
