A part of the TELINV2012 package is a manual and auxiliary GMT, Matlab and Fortran scripts for simple visualization of input data and model parameters and for preparation of input files.There was workshop on LaTeX, Scilab and SAGE in end of Nov.,12 at Abeda Inamdar College, Pune jointly organized by Dept.
The velocity perturbations are calculated in subsequent iteration steps, in which the ray paths and travel-time residuals are updated. The velocity perturbations are searched at nodes among which velocities are linearly interpolated. The latter one is implemented according to the Simplex ray-tracing technique. TELINV2012 is a code for calculation of velocity perturbations relative to 1D Earth velocity model from relative travel-time residuals.

Because of this program inverts only for the moment tensor components that are constrained by the observed data and gives a set of source mechanisms fitting the data.ĭemo MATLAB code to interactively move/resize selected area in a figure. This single-azimuth dataset cannot resolve the dipole perpendicular to the plane of stations and the hypocenter. The Fortran computer program retrieves source mechanisms of seismic events observed from a single (vertical or near vertical) array of receivers. As such, it allows describe general dipole sources including isotropic components: e.g., it is suitable to retrieve the parameters of both a shear dislocation common at foci of tectonic earthquakes (described as a double-couple, DC) and volumetric sources as tensile cracks or cavity implosions. The Fortran computer program performs inversion of amplitude ratios of SH and SV seismic waves together with polarities of P waves into the mechanism of the seismic source in the description of unconstrained moment tensor (MT).
