NanTroSEIZE: The IODP Nankai Trough Seismogenic Zone Experiment [PDF]
Scientific Drilling, 2006 The IODP Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) will, for the fi rst time ever, attempt to drill into, sample, and instrument the seismogenic portion of a plate-boundary fault or megathrust within a subduction zone.

Capturing 50 Years of Postseismic Mantle Flow at Nankai Subduction Zone [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractWe combine Global Positioning System, leveling, and tide gauge records of vertical motion in southwest Japan spanning postseismic deformation following the 1944 M8.1 Tonankai and 1946 M8.4 Nankai earthquakes. Continuous tide gauge records from 1950 to 2015 are combined with leveling data recorded from 1947 to 1980 and Global Positioning System ...

THERMOGENIC PETROLEUM POTENTIAL OF THE NANKAI SUBDUCTION ZONE, OFFSHORE SW JAPAN [PDF]
Journal of Petroleum Geology, 2019 In the Kumano forearc basin, offshore SW Japan, the potential occurrence of hydrocarbons has been inferred from both geophysical surveys which point to the presence of natural gas hydrates, and geochemical analyses of gas samples recovered from boreholes and submarine mud volcanoes.

The First D/V Chikyu IODP Operations: Successful Logging and Coring During NanTroSEIZE Stage 1 Expeditions [PDF]
Scientific Drilling, 2008 The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) is a multi-expedition IODP drilling project aimed at drilling, coring, logging, and instrumenting the seismogenic zone of an active subduction margin , in a region thought to generate megathrust

Rapid metabolism fosters microbial survival in the deep, hot subseafloor biosphere
Nature Communications, 2022 In the deep sedimentary biosphere, 80 °C has been proposed as an upper thermal barrier for life. Using a suite of radiotracer experiments, this study reports active methanogenic and sulfate-reducing microbial populations with high cell-specific metabolic

Earth, Planets and Space, 2022 Using global navigation satellite system (GNSS) data to detect millimeter-order signals of short-term slow slip events (S-SSEs) and to estimate their source parameters, especially duration, is challenging because of low signal-to-noise ratio.

Crustal resistivity structure around the Nankai subduction zone
BUTSURI-TANSA(Geophysical Exploration), 2005 The forearc crust along the Nankai Trough is characterized as an accretionary prism. The unconsolidated sediments on the subducting Philippine Sea plate are underplated to the southwest Japan arc, so that large amount of fluid is supplied to the accretionary prism.

Seismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake [PDF]
, 2006 The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5×1022 N-m, which corresponds to Mw=9.18.
