KILAUEA, Hawai'i (Island News) -- The 28th episode of Kilauea abruptly ended after hours of fountaining on Wednesday. The eruption ended at 1:20 p.m.

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.

Update at 3:37 p.m. July 9, 2025: Episode 28 of the ongoing episodic summit eruption of the Big Island’s Kīlauea volcano showed off a little, pumping molten rock geysers up to heights of about 1,200 feet from the north vent inside its Halemaʻumaʻu Crater.

The 27th episode of Kilauea started on Sunday morning. USGS reported that the episode officially started around 9 a.m., according to KITV. On Saturday, low-level precursory activity was reported when lava overflowed from the north vent.
