We develop a comprehensive description of three flavor neutrino oscillationsinside the Earth in terms of neutrino oscillograms in the whole range of nadirangles and for energies above 0.1 GeV. The effects of the 1-2 mass splittingand mixing as well the interference of the 1-2 and 1-3 modes of oscillationsare quantified. The 1-2 mass splitting and mixing lead to the appearance, apartfrom the resonance MSW peaks, of the parametric resonance peak forcore-crossing trajectories at E_nu ~= 0.2 GeV. We show that the interferenceeffects, in particular CP violation, have a domain structure with bordersdetermined by the solar and atmospheric magic lines and the lines of theinterference phase condition. The dependence of the oscillograms on the DiracCP-violating phase is studied. We show that for sin^2(2 theta13) < 0.1 thestrongest dependence of the oscillograms on delta is in the 1-2 and 1-3resonance regions.
