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.

Darwin VAAC is reporting a rare volcanic ash emission from a submarine volcano in the Bismarck Sea Volcanic Province, Papua New Guinea, since Monday, May 11, 2026. By Wednesday, May 13, ash was rising to about 4 km (13 000 feet) above sea level, while satellite imagery showed water discoloration near the advisory area. Meteorological cloud partly obscured the ash in the latest imagery, but Himawari-9 observations and model guidance continued to support the advisory.
The Alaska Volcano Observatory (AVO) raised Mount Kupreanof to Aviation Color Code Yellow and Volcano Alert Level Advisory at 17:01 UTC on May 12, 2026, after seismic activity and sulfur dioxide emissions increased over recent months at the Alaska Peninsula volcano.
Indonesia’s Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the alert level for Lewotobi Laki-laki in East Flores, East Nusa Tenggara, from Level II to Level III at 13:00 WITA (05:00 UTC) on May 12, 2026. The decision followed increased deep volcanic earthquakes, persistent non-harmonic tremor, inflation, and surface activity from May 1 to 11. Residents and tourists were told to avoid activity within a 5 km (3.1 miles) radius of the eruption center.
