Perturbational and nonperturbational inversion of Rayleigh-wave velocities
The inversion of Rayleigh-wave dispersion curves is a classic geophysical inverse problem. We have developed a set of MATLAB codes that performs forward modeling and inversion of Rayleigh-wave phase or group velocity measurements. We describe two different methods of inversion: a perturbational method based on finite elements and a nonperturbational method based on the recently developed Dix-ty...
متن کاملRayleigh Surface Wave Propagation in Transversely Isotropic Medium with Three-Phase-Lag Model
The present paper is dealing with the propagation of Rayleigh surface waves in a homogeneous transversely isotropic medium .This thermo-dynamical analysis is carried out in the context of three-phase-lags thermoelasticity model. Three phase lag model is very much useful in the problems of nuclear boiling, exothermic catalytic reactions, phonon-electron interactions, phonon scattering etc. The n...
متن کاملPhase velocities of rayleigh waves in the MELT experiment on the east pacific rise
The phase velocities of Rayleigh waves increase more rapidly with distance from the East Pacific Rise (EPR) axis than is predicted by models of conductive cooling of the lithosphere. Low velocities near the axis are probably caused by partial melt at depths of 20 to 70 kilometers in a zone several hundred kilometers wide. The lowest velocities are offset to the west of the EPR. Wave propagation...
متن کاملProblem of Rayleigh Wave Propagation in Thermoelastic Diffusion
In this work, the problem of Rayleigh wave propagation is considered in the context of the theory of thermoelastic diffusion. The formulation is applied to a homogeneous isotropic thermoelastic half space with mass diffusion at the stress free, isothermal, isoconcentrated boundary. Using the potential functions and harmonic wave solution, three coupled dilatational waves and a shear wave is obt...
متن کاملThe Deep Atlantic Ocean
The Atlantic Ocean is a long sinuous ocean which originated during the Mesozoic following the breakup of the supercontinent of Pangea. For most of its length, the eastern and western boundaries are clearly defined by land masses, except where it is separated from the Caribbean Sea and Gulf of Mexico by troughs and trenches. The northern and southern limits are more difficult to define. To the n...
