| Summary | Four-dimensional analysis using electromagnetic data is useful for monitoring volcanoes threatened by phreatic eruptions. In the past, 4D analysis has been performed by taking the difference of models estimated at each observation time, but its estimation accuracy and computational cost have been problematic. In this study, we propose a method that considers 4D analysis in the framework of joint inversion and imposes structural coupling between models at each observation time. The results of the synthetic test using magnetic inversion analysis show that changes in the model were concentrated closer to input model changes than in the conventional method of individual inversion. |
