Welcome to the wonderful world of AxiSEM3D, a flexible, high-performance computational method for solving elastodynamic wave equation in three-dimensional, hetereogeneous media. It has been used seismology Earth, Sun, Moon, and many other rocky planets moons Solar System. In this manual, we will explore practicalities using code, touching on mathematical aspects as relevant casual user, input output files, pre- post-processing. This guide is not replacement any AxiSEM3D papers, which you...
SUMMARY Although observation of gravity perturbations induced by earthquakes is possible, simulation seismic wave propagation in a self-gravitating, rotating Earth model with 3-D heterogeneity challenging due to the numerical complexities associated unbounded Poisson/Laplace equation that governs perturbations. Therefore, are generally omitted, and only background taken into account using so-called Cowling approximation. However, may be significant for large (Mw ≥ 6.0) long-period responses....
SUMMARY Seismic-wave scattering is observed, to variable degrees, on Earth, its moon and Mars. Current models data processing typically rely two end-member phenomena: weak, single- or multiple-scattering events (ballistic) the one hand, intense such that wavefield retains no path information bearing origin (diffuse).This study explores existence of behaviour intermediate between these end-members, as well properties heterogeneous media facilitate a transition them. We apply multiscale...
