Late Cenozoic seismic stratigraphy of the Andaman Forearc Basin, Indian Ocean
Andaman Forearc Basin Neogene Uplift Invisible Bank Outerarc Stratigraphy
2018/4/2
Interpretation of new multichannel seismic reflection data from the Andaman Forearc Basin (AFB) in the northern Indian Ocean is presented here. The highquality multichannel seismic data from the Andam...
Effect of glacial-interglacial sea-level changes on the displacement and stress field in the forearc and along the plate interface of subduction zones
glacial-interglacial sea-level stress
2015/1/4
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, becau...

Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, because the...
Megathrust friction determined from mechanical analysis of the forearc in the Maule earthquake area
Maule earthquake frictional properties dynamic weakening critical wedge

The seismogenic potential of a given fault depends essentially on its frictional properties and on the mechanical properties of the medium. Determining the spatio-temporal variations of frictional pro...
Origin and fate of deep-sea seeping methane bubbles at Kuroshima Knoll, Ryukyu forearc region, Japan
thermogenic hydrocarbons methane hydrates carbon isotopes helium isotopes Kuroshima Knoll microbial alteration propane
2017/8/9
Seafloor seeping methane bubbles were successfully sampled on the summit area of the Kuroshima Knoll (depth of ca. 640 m) using the gas-tight sampler WHATS attached to the Shinkai 2000. To evaluate th...
U-Pb zircon ages of syenitic and granitic rocks in the Ashizuri igneous complex, southwestern Shikoku: Constraint for the origin of forearc alkaline magmatism
U-Pb age zircon LA-ICP-MS Miocene alkaline magmatism Southwest Japan Outer Zone
2017/8/9
We report two first U-Pb zircon ages of the felsic rocks in the Ashizuri igneous complex, southwestern Shikoku, using the LA-ICP-MS. Samples are a syenite (ASH54) and a biotite granite (ASH5). Weighte...
