摘要：Identifying accurate topographic variations associated with volcanic eruptions plays a key role in obtaining information on eruptive parameters, volcano structure, input data for volcano processes modelling, and civil protection and recovery actions . The 2021 eruption of Cumbre Vieja volcano is the largest eruptive event in the recorded history for La Palma Island . Over the course of almost 3 months, the volcano produced profound morphological changes in the landscape afecting both the natural and the anthropic environment over an area of tens of km2 . We present the results of a UAS (Unoccupied Aircraft System) survey consisting of >12,000 photographs coupled with Structure- from-Motion photogrammetry that allowed us to produce a very-high-resolution (0 .2 m/pixel) Digital Surface Model (DSM) . We characterised the surface topography of the newly formed volcanic landforms and produced an elevation diference map by diferencing our survey and a pre-event surface, identifying morphological changes in detail . The present DSM, the frst one with such a high resolution to our knowledge, represents a relevant contribution to both the scientifc community and the local authorities.
