Morphology and dynamics of inflated subaqueous basaltic lava flows

A Deschamps, C Grigné, M Le Saout… - Geochemistry …, 2014 - Wiley Online Library
During eruptions onto low slopes, basaltic Pahoehoe lava can form thin lobes that
progressively coalesce and inflate to many times their original thickness, due to a steady …
