Volcano Remote Sensing，Geology of volcanoes
Volcanoes are widely distributed in various areas on the earth, and some of them are located in remote areas where access is difficult. Thus, remote sensing with satellites is becoming a common means of observing remote locations. We have worked on developing a combined analysis for eruptive activities that uses satellite images with high temporal resolution (e.g., Himawari-8) and multiple satellites that provide images with high spatial resolution and different properties. This approach has enabled us to obtain detailed information about eruption sequences and processes from a new point of view. For typical activity types, based on the comparative analysis using these results, the commonalities and differences in the eruption sequences are identified to extract their characteristics, and the generation mechanism and the relationship with the magma system are elucidated.
