Episodic lava fountaining is a rare volcanic behavior in which repeated, hours-long bursts of molten lava and gas are spewed from volcanic vents, with quiet pauses lasting days to weeks between episodes. These lava fountains have been observed in active volcanoes in places like Hawaii, Iceland and Italy, but researchers still do not fully understand what starts, sustains or stops these individual fountain episodes.

What's been driving Hawaii's lava fountains?
In most cases, hotspot-driven volcanism is relatively sedate, with lava flowing down mountainsides slowly enough that people can walk out of its way. But in a number of locations—Mount Etna, Hawaii, Iceland—lava gets expelled in dramatic fountains that can reach several hundred m
