Summary:
There are over 100 active volcanoes in Japan. A novel rescue system is needed can search for a survivor covered with volcanic ash. Toward the application of Sub-THz waves to the rescue system, we have already clarified the transmission characteristics of Sub-THz waves in the Sakurajima volcanic ash. Since ash compositions vary from volcano to volcano, the transmission characteristics are expected to vary from volcano to volcano. In this paper, transmission characteristics of sub-THz waves are measured on volcanic ash erupted from several volcanoes in Japan. In addition, we confirm the difference in transmission characteristics due to volcanic ash.
