Resumen:
In this communication we present TIERRAS,
an extension for the AIRES cosmic ray extended
air shower simulation program that enables
the four dimensional propagation of a cosmic ray
particle cascade underground, under-ice or underwater
up to energies of 1 ZeV and depths of 3 kilometers.
TIERRAS was developed as a new simulation
tool for shallow underground muon detectors but
it evolved to cover the shower simulation needs of
almost every type of ultra high energy cosmic ray
or neutrino experiment. Results are checked against
experimental measurements on underground laboratories
and compared with other particle propagation
codes, such as FLUKA or Geant4. The first results of
full underground shower simulations are presented,
including an example for shallow underground detectors
and another for hadron showers induced by
neutrinos having its first interaction in water, to be
used on neutrino telescopes on water or Ice. The
idea to use TIERRAS to track particles exiting the
ground either as albedo of an incoming cosmic ray
shower or from underground initiated showers, of
great interest for projected orbiting detectors, is also
discussed.
