Absorption neutrinography utilizes very high energy neutrinos with energies above 10 TeV to measure the nucleon density inside the earth whereas oscillation neutrinography measures the electron density by observing the MSW effect. Two independent physical quantities might provide new geophysical information, e.g., isotope ratio, to us. In this talk, a recent attempt to use atmospheric neutrinos for absorption neutrinography, based on a simulation of atmospheric neutrino events that can be collected with the IceCube neutrino detector, will be introduced as well as a possible oscillation neutrinography with Hyper-Kamiokande.
