Numerical inverse theory seismology global tomography seismic resolution Earth’ s mantle
2015/9/8
A fast technological progress is providing seismic tomographers with computers of rapidly increasing speed and RAM, that are not always properly taken advantage of. Large computers with both shared-me...
Wave-equation-based travel-time seismic tomography – Part 2: Application to the 1992 Landers earthquake (Mw 7.3) area
High resolution 3 d P wave S wave crust velocity poisson's ratio model landers earthquake earthquake fault
2015/1/6
High-resolution 3-D P and S wave crustal velocity and Poisson's ratio models of the 1992 Landers earthquake (Mw 7.3) area are determined iteratively by a wave-equation-based travel-time seismic tomogr...
Wave-equation-based travel-time seismic tomography – Part 1: Method
Travel seismic tomography step by step linearity sensitivity to the kernel
2015/1/6
In this paper, we propose a wave-equation-based travel-time seismic tomography method with a detailed description of its step-by-step process. First, a linear relationship between the travel-time resi...
Recently constructed tomographic models of the lateral heterogeneity of elastic properties in the Earth's mantle are contrasted in terms of their implications concerning the extent to which the endoth...
