New satellite measurements showing ground uplift around Mount Kupreanof have confirmed an ongoing magmatic intrusion beneath the volcano, adding a third line of evidence to months of elevated seismic activity and sulfur dioxide emissions. The Alaska Volcano Observatory (AVO) said the Aviation Color Code remains at Yellow and Volcano Alert Level at Advisory, with no indications from available data that an eruption is imminent.

Kīlauea’s ongoing summit eruption reached its 48th lava-fountaining episode in Halemaʻumaʻu crater, Hawaii, at 04:40 HST (14:40 UTC) on June 1, 2026, setting a written-record benchmark for episodic lava fountaining during a single Kīlauea eruption, according to the USGS Hawaiian Volcano Observatory (HVO). The episode ended abruptly at 13:37 HST (23:37 UTC) after just under 9 hours of continuous fountaining from the north vent, and the eruption was paused afterward.
The National Weather Service (NWS) in Honolulu issued an Ashfall Advisory for Hawaiʻi Volcanoes National Park and areas to the north and northeast, including Volcano and Mountain View, after Kīlauea’s episode 48 lava fountaining began inside Halemaʻumaʻu crater on June 1, 2026.
