“…The implications for lava emplacement characteristics (e.g., wide and engulfing pāhoehoe sheet flows vs. self-channelized, bulldozing 'a'ā flows) and the resulting hazards have been recognized for decades (Calabrò et al, 2020;Chevrel et al, 2013Chevrel et al, , 2018Chevrel et al, , 2019Cordonnier et al, 2016;Dragoni & Tallarico, 1994;Giordano et al, 2007;Harris & Rowland, 2001;Harris et al, 2020;Kolzenburg et al, 2016Kolzenburg et al, , 2017Kolzenburg et al, , 2020Kolzenburg, Di Genova et al, 2018;Peterson & Tilling, 1980). The surface morphology of the lava also modulates heat loss from the flow and, with that, determines how far a lava may advance prior to solidification (Ramsey et al, 2019).…”
