| Research Abstract |
To estimate 3-D deep structures, a new technique for survey is proposed based on simultaneous analysis of microtremor, gravity and magnetics. Observation systems and algorithm for noise reduction are developed for quick and accurate observation. Furthermore, techniques are also developed for joint inversion to analyze three different physical quantities simultaneously. The proposed techniques are applied to real fields and their adequacies are confirmed.
