  • Comparison with: (a) those from a global database of shield volcanoes; and (b) Grosse et al. (2014). The two are similar, apart from the long-short axis ratio; our cones are, on average, more circular than shield volcanoes elsewhere. This could be linked to specific glaciovolcanic eruption mechanisms, but is most likely a data bias due to our detection methods excluding more elliptical edifices.
