WHAT...An episodic fountaining eruption is expected within the Kilauea summit caldera. The Hawaiian Volcano Observatory has indicated a potential eruption window between now and June 1st. Fountaining episodes typically last less than 12 hours but ash can remain in the air longer depending on wind and weather. IMPACTS...If an eruption occurs, varying levels of ash, Pele's hair, and other lightweight tephra may fall downwind of the eruption. Smaller particles can travel farther from the eruption site and may affect communities at greater distances. Should a higher plume develop during this episode, south- southwesterly winds aloft could result in an easterly or northeasterly dispersion of ashfall instead.
