AB Aerial frames and satellite imagery are widely recognized data sources from which to producemaps. For volcanoes, maps enable the quantification of erupted ash and the destruction caused.The last eruptive sequence on Deception Island was endured from 1967 to 1970. Analogue mapswere produced via classical photogrammetric methods with a high degree of human interventionmainly to analyse the volcanic-centres areas only. However, historical aerial frames cover the wholeof Deception Island. Structure from motion photogrammetry, a near-automated compilation of digitalimage processing strategies, minimizes the degree of human intervention to produce orthographicmosaics and digital elevation models from digital aerial frames. Orthographic mosaics were producedfrom historical aerial frames of 1956 and 1968, and a Kompsat-3 image of 2020. Their shared rootmean-square deviation was 1.8 m and 1.7 m in easting and northing, respectively, at ground controlpoints measured with phase-differential global navigation satellite systems. The digital elevationmodels were processed with a root-mean-square deviation of 2.3 m and 3.6 m from 1956 and 1968aerial frames, respectively. As the first application, erupted ashfall and the subsequent destruction,mainly at the former Chilean and British bases, were identified, and the volume of erupted ash wasassessed to be over 0.16 km3 within the area mapped by these new digital cartographic products.
