Nankai accretionary prism
Witryna16 cze 2024 · Over most of its depth extent, the plate interface is interseismically locked, as defined by geodetic studies and a history of recurring large earthquakes and tsunamis, including the 1944 Mw 8.1 Tonankai event in which coseismic rupture extended to within 30 to 40 km of the trench ( 20, 21 ). WitrynaThe NanTroSEIZE drilling transect in the Nankai accretionary prism is located offshore of the Kii peninsula (Fig. 1a). In this transect, the sedimentary pile of the prism may be subdivided into sediments of the Kumano forearc basin, slope or trench sediments, and accreted sediments underneath (Fig. 1b).

Witryna1 mar 2010 · The LVZ could be an underthrust package underplated in response to the lateral growth of the Nankai accretionary prism. Underplating of the underthrusting layer beneath the overlying offscraped layer would maintain a critical taper of the accretionary prism so that the offscraped layer can continue to grow seaward. The …

Within the Nankai Trough there is a large amount of deformed trench sediments (Ike, 2004), making one of Earth's best examples of accretionary prism. Furthermore, seismic reflection studies have revealed the presence of basement highs that are interpreted as seamounts that are covered in … Zobacz więcej The Nankai Trough (南海トラフ, Nankai Torafu, Southern Sea Trough) is a submarine trough located south of the Nankaidō region of Japan's island of Honshu, extending approximately 900 km (559 mi) … Zobacz więcej Conventional geologic estimates of plate movement velocities are difficult in the Nankai Trough because there are no spreading ridges that bound the tectonic plate. This area was not in the original NUVEL models (DeMets et al., 1990). However, a … Zobacz więcej The Nankai Trough is actively deforming and marks a region of seismic activity. Deformation is concentrated in the outermost imbricate zone, with a significant amount of "out of sequence" thrusting occurring landward. Based on the work of … Zobacz więcej Drill cores from the seaward edge of the Nankai Trough (where the heat flow is one of the highest in the region) reveal that sediments there only reach pre-oil window to early oil window thermal maturities. However, the trough is potentially a major source of … Zobacz więcej The deposits in the trough are primarily trench-wedge turbidites (Spinelli et al., 2007). There are indications of an increase in the retention of porosity within the rock. … Zobacz więcej The Nankai Trough is the near-surface extension of a zone of active seismicity that dips beneath SW Japan. The rupture zone has been subdivided into five areas with respect to seismic modelling (Mitsui et al., 2004). These five subdivisions show interesting … Zobacz więcej The Nankai accretionary complex is an area with high heat flow. Its thermal history is complex due to multiple heating events or property … Zobacz więcej WitrynaIt is important to investigate the shallow deformation structure for understanding the development of plate boundary fault at the trench axis in Nankai seismogenic zone. We imaged the bathymetric detailed features using red relief image map method and high-resolution sub-surface structure obtained by sub-bottom profiling at the trench axis in ...
