Abstract

Volcanic smoke of Sakurajima and Kirishima has been observed by Ku band radar (Ku-RAD) of Kagoshima University. In addition, Marine Radar had shorter search time than Ku-RAD was able to observe volcanic smoke. On the other hand, Marine Radar produced a transmission signal in magnetron which was necessary to change magnetron in a fixed period. This time, we borrowed Solid-state Marine Radar which was no necessary to change solidified transmission device and can observe volcanic smoke. At first 100W and 400W Solid-state Marine Radar was installed in the Kagoshima University Shimoarata campus roof and measured the Sakurajima area in PPI and RHI. Furthermore, to move, and to observe eruption of Sakurajima, install the radar for the ship in the boat, while it traveled the sea, the volcanic smoke of Sakurajima was observed. These observation methods were effective for volcanic ashes observation.
