Fig. 6From: A new method to reconstruct the 3D ground surface temperature from aerial TIR and visible images: application to the active crater of Aso volcano, JapanOrthorectified thermal images zoomed in on the first crater (a 2020 survey and b 2022 survey) and thermal anomalies (c 2020 and d 2022). Both maps a and b show a high-temperature fumarolic field on the south crater wall (I) and steaming grounds scattered on the crater floor and southwest wall (II)Back to article page
