Overview
- Eruption began early on September 2 at Kīlauea’s summit, sending lava fountains widely reported around 150 meters high, with some imagery suggesting bursts approaching 300 meters.
- The activity was limited to the Halemaʻumaʻu crater inside Hawaiʻi Volcanoes National Park, where authorities restricted access to certain viewpoints and hazard areas.
- USGS set the volcano alert level to Watch and the Aviation Color Code to Orange, maintaining heightened surveillance of the summit.
- Reports from park and media updates indicate the eruption ceased abruptly shortly after 20:00 local time on September 2, though monitoring remains in place.
- Public-health guidance highlights sulfur dioxide, vog, and fine glassy filaments known as Pele’s hair, and experts note the frequent summit episodes since December 2024 can relieve pressure and influence fountain style.
