Fig. 7From: Phreatic eruption dynamics derived from deposit analysis: a case study from a small, phreatic eruption from Whakāri/White Island, New ZealandField images of the pyroclastic density current (PDC) and the impacts on pre-existing field markers. a Sheared yellow plastic pegs at the PDC base are clearly evident, as well as damaged wooden stakes (b and c) that are broken and now leaning or snapped away from the crater lake. d The deposit exhibits a weakly erosional basal contact and is fine-grained and poorly to very poorly sortedBack to article page
