Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.

Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra-subduction zone ophiolites [PDF]

, 2015
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the ...

Geological record of prehistoric tsunamis in Mugi town, facing the Nankai Trough, western Japan

Progress in Earth and Planetary Science, 2019
Stratigraphic and paleontological investigations in Mugi Town, on the Pacific coast of Shikoku Island, revealed evidence of as many as five tsunami inundations from events along the Nankai Trough between 5581 and 3640 cal yr BP.

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 ...

Filling the Gap in Cascadia: The Emergence of Low‐Amplitude Long‐Term Slow Slip

Geochemistry, Geophysics, Geosystems, 2021
Long‐term slow slip events have been observed at several subduction zones around the globe, where they play an integral part in strain release along megathrust faults.

Distribution of stress state in the Nankai subduction zone, southwest Japan and a comparison with Japan Trench [PDF]

, 2015
To better understand the distribution of three dimensional stress states in the Nankai subduction zone, southwest Japan, we review various stress-related investigations carried out in the first and second stage expeditions of the Nankai Trough ...

Long-term slow slip events along the Nankai trough delayed by the 2016 Kumamoto earthquake, Japan

Earth, Planets and Space, 2020
The Global Navigation Satellite System network in Japan detected transient crustal deformation along the Nankai trough, Japan, from June 2018. Time-dependent inversion analysis shows that a long-term slow slip event in northern Hyuga-nada Sea along the ...

Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319

, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure
