Subducting lithospheric plates are the cool, downwelling limbs of mantle convection and the negative buoyancy of subducting slabs (slab pull) drives plate tectonics [Forsyth and Uyeda, 1975]. Subduction zones are regions of intense earthquake activity, explosive volcanism, and complex mass transfer between the crust, mantle, hydrosphere, and atmosphere. In this contribution, I present subductio...

Extreme coastal inundation associated with the 2004 Indian Ocean and 1945 Makran tsunamigenic-earthquakes highlight the risk of tsunamis to coastlines of the northern Oman Sea. Foraminifera have been used as indicators of paleotsunamis in the past where allochthonous tests, found in low-energy environments such as in coastal lagoons, ponds, and marshes, indicate marine overwash. In this study, ...

Geophysical data from the offshore Cascadia forearc reveal many Quaternary upper-plate faults and folds. Most active structures are within the accretionary wedge, but significant deformation is also found on the continental shelf. Several faults and synclines project into adjacent coastal bays where deformation of Pleistocene marine terraces is reported. Rapidly buried marsh deposits and drowne...

To delineate the spatial distribution of high saturation gas hydrate reservoirs in low-angle subduction areas Makran Accretionary Prism, we conducted seismic data interpretation and impedance inversion hydrates Prism comprehensively analyzed characteristics Nankai Trough Japan Shenhu Area South China Sea. The results show that features thick sediments, developed transport systems “two-way suppl...

IT IS generally agreed that the Marfan syndrome is a heritable disorder of connective tissue characterized by widespread malformations affecting the musculoskeletal, cardiovascular, and ocular systems. It was first described by Marfan in 1896 under the name of dolichostenomelie.' In 1902 Archard presented a case and called the syndrome arachnodactyly.2 Thus, the musculoskeletal malformations we...

Subduction earthquakes on plate-boundary megathrusts accommodate most of the global seismic moment release, frequently resulting in devastating damage by ground shaking and tsunamis. As many earthquakes occur in deep-sea regions, the dynamics of earthquake faulting in subduction zones is poorly understood. However, the Integrated Ocean Drilling Program (IODP) Nankai Trough Seismogenic Zone Expe...

[1] Arc volcanism is intimately linked to mineral dehydration reactions in the subducting oceanic mantle, crust, and sediments. The location of slab dehydration reactions depends strongly on the temperature and pressure conditions at the top of the subducting plate and hence on the detailed thermal structure of subduction zones. A particularly important physical property of subduction zone ther...

[1] The fine-scale seismic structure of the central Mexico subduction zone is studied using moderate-sized (M4-6) intraslab earthquakes. Regional waveforms from the Mapping the Rivera Subduction Zone (MARS) seismic array are complicated and contain detailed information about the subduction zone structure, including evidence of lateral heterogeneity. This waveform information is used to model th...
