Overview
- The eruption began early Monday and produced sustained summit fountaining from the Halemaʻumaʻu north vent that peaked near 200 m (about 650 ft) before gradually declining.
- The National Weather Service issued an ashfall advisory for Hawaiʻi Volcanoes National Park and downwind communities after ash, tephra and Pele’s hair were reported at park overlooks, along Highway 11 and in nearby towns.
- USGS/HVO said lava and tephra remained confined to the summit caldera and Kaluapele with no notable activity on Kīlauea’s East or Southwest Rift Zones.
- Dozens to about 95 brief overflow events from the south vent in late May preceded the fountaining, signaling rising summit unrest before episode 48 began.
- Scientists and forecasters are continuing seismic, deformation and plume monitoring while warning residents and visitors to limit exposure, protect water catchments and expect possible travel or flight impacts from ash.
