A Map of Iceland showing the location of Askja (red box). B CNES Airbus satellite image from Google Earth of Askja volcano, with Lake Öskjuvatn and the 1961 lava flow within the white box. C Greyscale aerial photo (taken by Loftmyndir ehf) (1 m/pixel) of the 1961 lava flow showing outlines of flow lobes from each eruptive event, differentiating predominant lava texture type (aʻa or pahoehoe). ‘phh’ = pahoehoe; ‘PB’ = pahoehoe breakout; “Branch” = locations where flow bifurcates. Locations of topographic profiles and samples are shown, sample names are abbreviated to collection year and sample number. D SPOT satellite imagery (2.5 m/pixel) displaying sample locations at the vents
