A review on slow earthquakes in the Japan Trench [PDF]

Progress in Earth and Planetary Science, 2023
Slow earthquakes are episodic slow fault slips. They form a fundamental component of interplate deformation processes, along with fast, regular earthquakes.

Mantle-derived helium released through the Japan trench bend-faults [PDF]

Scientific Reports, 2021
Plate bending-related normal faults (i.e. bend-faults) develop at the outer trench-slope of the oceanic plate incoming into the subduction zone. Numerous geophysical studies and numerical simulations suggest that bend-faults play a key role by providing ...

Incoming plate structure at the Japan Trench subduction zone revealed in densely spaced reflection seismic profiles

Progress in Earth and Planetary Science, 2023
The structure of the incoming plate is an important element that is often considered to be related to the occurrence of great earthquakes in subduction zones.

Distribution and niche separation of planktonic microbial communities in the water columns from the surface to the hadal waters of the Japan Trench under the eutrophic ocean [PDF]

Frontiers in Microbiology, 2016
The Japan Trench is located under the eutrophic Northwestern Pacific while the Mariana Trench that harbors the unique hadal planktonic biosphere is located under the oligotrophic Pacific. Water samples from the sea surface to just above the seafloor at a

Submarine paleoseismology in the Japan Trench of northeastern Japan: turbidite stratigraphy and sedimentology using paleomagnetic and rock magnetic analyses

Progress in Earth and Planetary Science, 2023
Previous studies of sediments recovered from the Japan Trench between 37° 25′ N and 38° 30′ N document distinctive turbidite beds induced by huge earthquakes.

How large peak ground acceleration by large earthquakes could generate turbidity currents along the slope of northern Japan Trench

Progress in Earth and Planetary Science, 2023
Deep-sea turbidite has been used to determine the history of occurrence of large earthquakes. Surface-sediment remobilization is a mechanism of the generation of earthquake-induced turbidity currents.

The present-day stress field along the Northwest Pacific Wadati-Benioff zone constrained by focal mechanisms of moderate earthquakes

Frontiers in Earth Science, 2023
The present-day stress field in the northwest Pacific Wadati-Benioff Zone (WBZ) has been investigated on the basis of earthquake focal mechanism catalog covering the period from 2012 to 2021. Our catalog contains 201 focal mechanism solutions (Mw 4.0–5.9)

Microbiome in an Office Building Using a Cooling Trench as an Outdoor Air Duct [PDF]

E3S Web of Conferences, 2019
Subterranean temperature at a depth of 10 m is almost equal to the average outdoor air temperature of the same area. Therefore, if a building cooling trench is used as an outdoor air duct, outdoor air can be cooled in summer and warmed in winter.
