Interpretaion of 2-D Magnetotelluric Profile Data with 3-D Inversion Synthetic Examples

W. Siripunvaraporn○, M. Uyeshima（東大地震研） and G. Egbert（オレゴン州立大）

1. Inverting 3-D Data with 2-D inversion can be DANGEROUS!　2. 2-D Inversion will put off-profile structures into the 2-D inverted　model, in order to fit the data better.　3. Problems can be avoid if applying 3-D inversions, especially using all　impedance tensor components.　4. Zxx and Zyy help providing additional constraint information about the　direction of conductors.　 5. (if time permitted) A 3-D conductivity structure beneath Miyake-jima　Island wil be shown.
