Abstract
All recent available data sets containing traveltimes of Pg and Sg phases for the Moravo-Silesian region were collected. These data come from several experiments designed mostly in 2D (in-line) configurations. Simultaneous processing of all data is possible only considering the true 3D measurement geometry. The goal of this work is to establish the representative 3D seismic model by means of seismic tomography. The resulting minimum-structure model is presented in a simple and easy to use form on the Internet. The amount of processed data is relatively low but repeating the computations with new experimental data included would be very easy. Important material related to this paper is placed on web pages.
