Kohtaro Ujiie spends much of his time researching Seismology, Subduction, Slip, Accretionary wedge and Trench. His Seismology study combines topics from a wide range of disciplines, such as Drilling and Petrology. His work carried out in the field of Subduction brings together such families of science as Fault, Cataclastic rock, Plate tectonics and Shear.
His study looks at the relationship between Fault and fields such as Interplate earthquake, as well as how they intersect with chemical problems. In his study, which falls under the umbrella issue of Slip, Fault slip, Thrust and Coseismic slip is strongly linked to Shear stress. In his papers, he integrates diverse fields, such as Trench, Stress drop and Moment magnitude scale.
His primary scientific interests are in Seismology, Subduction, Petrology, Slip and Fault. In general Seismology study, his work on Plate tectonics, Accretionary wedge and Décollement often relates to the realm of Trench, thereby connecting several areas of interest. His Subduction research is multidisciplinary, relying on both Geochemistry and Submarine pipeline.
The study incorporates disciplines such as Metasomatism, Structural geology, Viscous shear and Tectonophysics in addition to Petrology. His Slip research focuses on subjects like Mineralogy, which are linked to Shear stress. His work on Seismic slip and Fault gouge as part of his general Fault study is frequently connected to Raman spectroscopy, thereby bridging the divide between different branches of science.
Kohtaro Ujiie mainly focuses on Subduction, Petrology, Seismology, Tectonophysics and Accretionary complex. His Subduction research includes elements of Thrust, Brittleness, Fault, Viscous shear and Slip. He has researched Slip in several fields, including Shear strain rate and Décollement.
Kohtaro Ujiie has included themes like Metasomatism, Mantle, Basalt and Plate tectonics in his Petrology study. His research in Seismology is mostly concerned with Accretionary wedge. His Tectonophysics research incorporates elements of Geochemistry and Structural geology.
The scientist’s investigation covers issues in Subduction, Petrology, Slip, Basalt and Shear. His Subduction study contributes to a more complete understanding of Seismology. His Slip research includes themes of Décollement, Drilling, Porosity and Accretionary wedge.
His work deals with themes such as Slow earthquake and Mélange, which intersect with Basalt. His Shear research incorporates elements of Creep, Quartz, Shear zone and Oceanic crust. His research integrates issues of Megathrust earthquake, Felsic, Mafic and Underplating in his study of Fault.
