[SVC47-P03] Applicability evaluation of the drone-mounted thermal infrared camera to geothermal monitoring at Sumikawa site, Akita Prefecture
Keywords:drone, geothermal monitoring, temperature distribution map, Sumikawa site
This presentation would introduce a case study of thermal monitoring at the Sumikawa hot spring where a small phreatic explosion occurred in 1997. In particular, we observed the thermal distribution of the surface using a drone-mounted thermal infrared camera on the 18th October, 2015. And a temperature distribution map with high spatial resolution, roughly 5 cm, was generated from the data. This high resolution map would be made it possible for us to acquire the precise information of geothermal anomaly at the relatively small fumarolic area. Therefor, this method could complement the conventional observing approach of geothermal activity by performing repeatedly with proper timing.
