In this paper we present TIERRAS, a Montecarlo simulation program based on the well known AIRES air shower simulations system that enables the propagation of particle cascades underground, providing a tool to study particles arriving under ground from a primary cosmic ray on the atmosphere or to initiate cascades directly underground and propagate them, exiting into the atmosphere if necessary.   We show several cross-checks of its results against FLUKA, GEANT4 and CORSIKA simulations and we make some considerations regarding its possible use and limitations. The first results of full underground shower simulations are presented, as an example of the package capabilities.
