Activation of very low frequency earthquakes by slow slip events in the Ryukyu Trench [PDF]
Geophysical Research Letters, 2015 AbstractLong‐term activity of shallow very low frequency earthquakes (VLFEs) in the Ryukyu Trench, unassociated with recent large thrust earthquakes, was analyzed using a broadband seismometer network. The distribution of shallow VLFEs was divided into three large clusters.

Distribution of low-frequency earthquakes accompanying the very low frequency earthquakes along the Ryukyu Trench [PDF]
Earth, Planets and Space, 2017 This study investigated the activity and distribution of low-frequency earthquakes (LFEs) accompanying the very low frequency earthquakes (VLFEs) in the central and southern Ryukyu Trench.

Interchanges and movements of humpback whales in Japanese waters: Okinawa, Ogasawara, Amami, and Hokkaido, using an automated matching system. [PDF]
PLoS ONE, 2022 Humpback whales in the western North Pacific are considered endangered due to their small population size and lack of information. Although previous studies have reported interchanges between regions within a population, the relationship between the ...

Episodic Slow Slip Events and Overlying Plate Seismicity at the Southernmost Ryukyu Trench
Geophysical Research Letters, 2018 AbstractShallow slow slip events accompanied by seismicity has been increasingly reported in subduction zones during the last decade; however, the relationship between shallow slip events and seismicity is unclear. We report episodic slow slip events and seismicity at the southernmost Ryukyu Trench.

Potential coupling of microbial methane, nitrogen, and sulphur cycling in the Okinawa Trough cold seep sediments [PDF]
Microbiology SpectrumThe Okinawa Trough (OT) is a back-arc basin with a wide distribution of active cold seep systems. However, our understanding of the metabolic function of microbial communities in the cold seep sediments of the OT remains limited.

Slab Pull Drives IBM Trench Advance Despite the Weakened Philippine Sea Plate
Geophysical Research Letters, 2023 The mechanism behind the significant Izu‐Bonin‐Mariana (IBM) trench advance is still controversial. We conduct slab subduction numerical models that reproduce the spatio‐temporal tectonic evolution of the Philippine Sea region to investigate whether slab

Variations in the crustal structure and strength of plate coupling along the Ryukyu subduction zone
Geoscience Letters, 2023 The Ryukyu trench-arc-back arc system is part of the subduction margins of the Philippine Sea plate. Previous studies have indicated that several geophysical and geological characteristics reveal significant variations (including convergent rate ...
