Kīlauea, Hawaiʻi — Eruption Paused, Episode 46 Forecasted for May 5–9 As of April 30 (18:29 UTC), the Hawaiian Volcano Observatory (HVO) has downgraded Kīlauea to Alert Level ADVISORY / Aviation Color Code YELLOW. The summit eruption is currently paused. However, rapid return of inflationary ground deformation — tracked by summit tiltmeters — suggests that Episode 46 is forecast to begin between Tuesday, May 5 and Saturday, May 9, 2026. Observers should watch HVO updates closely as the forecast window narrows.
Ibu, Indonesia — Ash Advisory Issued (April 29) Ibu volcano on Halmahera Island, Indonesia, generated an eruption reported at 10:02 UTC on April 29, with a volcanic ash advisory (VAAC) issued at 11:40 UTC. Satellite imagery from April 29 confirmed activity at the summit.
Multi-Volcano Roundup (April 29) The latest daily volcano news bulletin reported several noteworthy events:
- Popocatépetl (Mexico): 136 exhalations recorded, with some incandescence observed.
- Reventador (Ecuador): Pyroclastic flows reported.
- Kīlauea (Hawaiʻi): Volcanic gases igniting in summit vents, continuing signs of unrest ahead of Episode 46.
USGS Volcano Watch — Kīlauea Summit Eruptions Outside Halemaʻumaʻu (Published ~18 hours ago) A new USGS Volcano Watch article — published approximately 18 hours before press time — examines the broader hazard picture at Kīlauea, discussing eruptions from the summit region beyond the familiar Halemaʻumaʻu crater. The piece highlights the risks posed by shallow earthquakes and ground deformation at the summit, relevant context as scientists watch for Episode 46.
Earth Science
Preparedness Tip — Kīlauea Episode 46 Watch With USGS tiltmeter data pointing to an upcoming eruptive episode at Kīlauea between May 5–9, residents and visitors near the Hawaiʻi Volcanoes National Park summit area are encouraged to monitor HVO updates daily. Volcanic gas emissions (primarily SO₂) can spike rapidly at episode onset and pose respiratory hazards, particularly for those with cardiovascular or pulmonary conditions. Lava viewing conditions may change quickly once an episode begins. Check the USGS Volcano Updates page for the latest alerts.
