Modeling seismic energy propagation in highly scattering environments

Modeling of Fault Co-seismic Displacement Fields in Elastic Environments Based on Spherical Dislocation Theory

This research is based on the modeling of co-seismic deformations due to the fault movement in the elastic environments, and we can obtain the deformations generated in the faults. Here, modeling of the co-seismic displacement field is based on the analytical method with two spherical dislocation model and half-space dislocation model. The difference in displacement field from two spherical and...

Monte Carlo Modeling of Photon Propagation Reveals Highly Scattering Coral Tissue

Corals are very efficient at using solar radiation, with photosynthetic quantum efficiencies approaching theoretical limits. Here, we investigated potential mechanisms underlying such outstanding photosynthetic performance through extracting inherent optical properties of the living coral tissue and skeleton in a massive faviid coral. Using Monte Carlo simulations developed for medical tissue o...

Modeling of global seismic wave propagation on the Earth Simulator

We use the Earth Simulator to model seismic wave propagation resulting from large earthquakes on a global scale. Simulations are conducted based upon the spectral-element method, a high-degree finiteelement technique. We include the full complexity of the Earth, i.e., a three-dimensional seismic wave velocity and density structure, a 3-D crustal model, the elliptical figure of the Earth as well...

Modeling Seismic Wave Propagation Using Graphics Processor Units (GPU)

The main drawback of the seismic modeling in 2D viscoelastic media on a single PC is that simulations with large gridsizes require a tremendous amount of floating point calculations. To improve computation speedup, a graphic processing units (GPUs) accelerated method was proposed using the staggered-grid finite difference (FD) method. The geophysical model is decomposed into subdomains for PML ...
