Surface temperature changes of the crater of Agung Volcano from Landsat-8 TIRS during 2017-2018 eruption

Abstract

This paper described the application of Landsat-8 TIRS (Thermal Infra Red Sensor) to analyze the surface temperature changes of the crater region of Agung volcano during early of 2013 until late of 2019. Agung volcano is an active stratovolcano located in Bali island. We processed the brightness temperature from channel-10 of Landsat-8 TIRS during early of 2013 - late of 2019 and analyzed the changes. The results of this research showed that the eruptions that occurred during 2017 - 2018 have indicated highly increasing in the surface temperature of the crater region. The surface temperature changes of the crater region, which can be detected from Landsat-8 TIRS data, can be used as a precursor of an eruption.
