Thermal remote sensing is currently an emerging technique for monitoring active volcanoes around the world. The study area, the Aso volcano, is currently the most active and has erupted almost every year since 2012. For the first time, Landsat 8 TIRS thermal data were used in this study area to eval...

The Hatchobaru–Otake (HO) geothermal field is proximal to the Kuju volcano on Kyushu, Japan. There are currently three geothermal power plants operating within this geothermal field. Herein, we explore the thermal status of the HO geothermal area using ASTER thermal infrared data to monitor heat los...

Three major successive plinian or subplinian eruptions, following a long dormant period, occurred in January 2011, September 2017, and March 2018 within the Kirishima volcano complex on Kyushu Island, Japan. Herein, we applied a Landsat 8 image to explore the most active hydrothermal altered area of...

The Beppu geothermal area, one of the largest spa resorts on the northeast Kyushu Island of Japan, is fed by hydrothermal fluids beneath the volcanic center of Mt. Garan and Mt. Tsurumi in the west. We explored the thermal status of the Beppu geothermal area using nighttime multisource satellite the...

The prime objective of our study was to monitor heat losses by using Landsat 7 thermal infrared data from the active fumarolic region of Kuju volcano in Japan. We estimated the radiative heat flux (RHF) of the Kuju fumaroles from 2002 to 2010, used the Stefan -Boltzmann equation. Then, heat discharg...

The Unzen geothermal field, our study area is active fumaroles, situated in Shimabara Peninsula of Kyushu Island in Japan. Our prime objectives were (1) to estimate radiative heat flux (RHF), (2) to calculate approximately heat discharge rate (HDR) using the relationship of radiative heat flux with ...
