HONOLULU (KHON2) — The latest episode of the ongoing Halemaʻumaʻu eruption at Kilauea volcano ended at 9:18 a.m. HST on Thursday, February 20, after nearly 13 hours of active lava fountaining, according to the U.S. Geological Survey (USGS).

The eruption began early in the morning and saw lava flows cover 75% of the floor of Halemaʻumaʻu, located in the southern part of Kilauea caldera.

Activity from the north vent gradually declined throughout the episode before it stopped.

The end of the eruption was marked by a shift from deflation to inflation at the summit and a drop in seismic tremor intensity.

Since December 23, 2024, episodes of lava fountaining at Halemaʻumaʻu have lasted anywhere from 13 hours to 8 days, with brief pauses in activity lasting from less than a day to up to 12 days.

The current Volcano Alert Level remains at WATCH, with an Aviation Color Code of ORANGE.

The volcano’s activity remains confined to Hawaii Volcanoes National Park.

The Hawaiian Volcano Observatory (HVO) will continue to monitor the situation closely and will provide an update on Friday morning unless significant changes occur before then.
