Overview
- The latest summit eruption began Saturday on Hawaiʻi Island and persisted for more than 12 hours, with activity focused at the south vent.
- USGS documented sustained lava fountains reaching about 400 meters and frequent overflows, including 24 south‑vent overflows reported on Saturday.
- The alert level remains orange at least through November 26 as scientists track sulfur dioxide emissions and watch for additional episodes.
- Lava covered more than three quarters of the summit crater floor but stayed within Hawaiʻi Volcanoes National Park and has not threatened homes or buildings.
- Researchers consider the dozens of events since December 2024 part of a single ongoing eruption following the same magma pathway, with viewing possible from park overlooks and official livestreams.
