The 28th episode of Kilauea abruptly ended after hours of fountaining on Wednesday. The eruption ended at 1:20 p.m. The new eruption started early Wednesday morning at Halemaʻumaʻu Crater in Hawaiʻi Volcanoes National Park.

HAWAII VOLCANOES NATIONAL PARK (HawaiiNewsNow) - Fountaining from the latest episode of the ongoing eruption at the summit of Kilauea volcano ended shortly before 8 p.m. Sunday, but not before another spectacular show with lava shooting more than a thousand feet into the sky.

Another explosive episode of Kilauea’s volcanic activity came and went Wednesday after Episode 28 of the ongoing eruption in Halemaumau Crater saw eight hours of high fountaining.

Essentially, gas pistoning is a shallow, degassing-driven rise and fall of a lava surface. Often these pistons occur in narrow conduits — although they can happen in larger lava lakes and even in lava channels — and in bunches, as part of a series.

Episode 28 of the ongoing Halemaʻumaʻu eruption began at 4:10 a.m. on July 9 and is currently exhibiting a vent overflow and fountains reaching roughly 150 feet. Past episodes have produced incandescent lava fountains over 1000 feet high that result in eruptive plumes up to 20,000 feet above ground level.
