Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps
EcosphereCold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much

Thick slab crust with rough basement weakens interplate coupling in the western Nankai Trough
Earth, Planets and SpaceThe westernmost Nankai Trough, southwest Japan, exhibits a rapid along-strike reduction in plate coupling in the proximity to the subducting Kyushu-Palau ridge. Yet how and to what extent the ridge subduction impacts physical properties at the megathrust

Characteristics of a tsunamigenic megasplay fault in the Nankai Trough [PDF]
Geophysical Research Letters, 2013 Slip on the shallow part of a megasplay fault that is an out‐of‐sequence thrust and branch of the main subduction plate boundary can cause devastating tsunamis after earthquakes. We analyzed the three‐dimensional geometry, including dip amount and azimuths, roughness distributions, and thickness variations, of the shallow part of a megasplay fault in ...

Thermogenic methane and hydrogen generation in subducted sediments of the Nankai Trough
Communications Earth & EnvironmentActive and widespread CH4 accumulations and emissions in the Nankai Trough subduction zone are attested by numerous mud volcanoes, gas plumes, and gas hydrates containing biogenic and thermogenic CH4.
