TRACKING AN ACTIVE ERUPTION FOR INSIGHT INTO THE DYNAMICS BEHIND PLANETARY VOLCANIC FEATURES
During the eruption, features formed that have distinct similarities to volcanic features observed on the Moon and Mars. A small rampart with a short channel that formed during the initial stages of eruption at Fissure 22 is very similar to a small cone and channel observed in Mare Tranquillitatis, the Moon. The Fissure 22 rampart, channel, and marginal levees formed within days, suggesting the analogous cone on the lunar surface resulted from a day(s)-long, low-volume eruption. In the Fissure 8 channel, terraces similar to those observed within Athabasca Valles, Mars formed in the channel wall as the depth and width of lava within the channel decreased and are, therefore, indicative of the level of lava within the channel. Also, sinuous lava channels formed at Fissures 8 and 22 have a similar morphology to channels observed on the Moon and Mars, with diverging and converging channel branches surrounding streamlined islands in the channel interiors. In Hawaii, these islands are kipukas of pre-existing terrain surrounded by lava, and they formed within months of the onset of the eruption. These and other analogous features will be explored to gain insight into the timing and dynamics behind the formation of enigmatic planetary features.
