  High-energy neutrino astronomy represents an open window both on
astrophysical mechanisms of particle acceleration and on fundamental
interactions. The possibility of detecting them in large earth-based apparatus,
like AUGER, AMANDA, ANTARES, is quite challenging. In view of this, the
capability of generating reliable simulations of air showers induced by
neutrinos is mandatory in the analysis of experimental data. In this paper we
describe preliminary results towards the development of a new version of the
Monte Carlo CORSIKA, capable of handling neutrinos too as primary particles. In
our approach the first interaction of the primary neutrino is simulated in
CORSIKA with a call to the HERWIG event generator.
