Hawaii, United States – Episode 45 of Kīlauea’s summit lava fountaining began at 1:34 a.m. HST on April 23 and is still ongoing.

Lava fountains at the north vent are currently reaching heights of around 700 feet (200 meters). Wind is blowing from the north, meaning volcanic gas and material may be carried toward the south and southwest from Halemaʻumaʻu.

The National Weather Service Honolulu Forecasting Office has issued an Ashfall Advisory for the District of Kaʻū, located southwest of the eruptive vents.

Officials said fountaining episodes typically last 12 hours or less, though ash may remain in the air longer depending on wind and weather conditions.

Authorities are advising the public to stay alert and follow official updates from the USGS, the National Weather Service, and Hawaiʻi Volcanoes National Park.

The eruption remains active in the early hours of April 23, 2026.
