  abstract = {{I}n this study, the geomorphological evolution of an inner flank of the {C}rat & egrave;re {D}olomieu at {P}iton de {L}a {F}ournaise/{L}a {R} & eacute;union was investigated with the help of terrestrial laser scanning ({TLS}) data, terrestrial photogrammetric images, and historical webcam photographs. {W}hile {TLS} data and the terrestrial images were recorded during three field surveys, the study was also able to use historical webcam images that were installed for the monitoring of the volcanic activity inside the crater. {A}lthough the webcams were originally intended to be used only for visual monitoring of the area, at certain times they captured image pairs that could be analyzed using structure from motion ({S}f{M}) and subsequently processed to create digital terrain models ({DTM}s). {W}ith the help of all the data, the geomorphological evolution of selected areas of the crater was investigated in high temporal and spatial resolution. {S}urface changes were detected and quantified on scree slopes in the upper area of the crater as well as on scree slopes at the transition from the slope to the crater floor. {I}n addition to their quantification, these changes could be assigned to individual geomorphological processes over time. {T}he webcam photographs were a very important additional source of information here, as they allowed the observation period to be extended further into the past. {B}esides this, the webcam images made it possible to determine the exact dates at which geomorphological processes were active.},
