Key Takeaways

  • Lava fountains reached between about 1,000 and 1,300 feet high.
  • Falling ash and glassy volcanic fragments prompted ash-fall warnings and protective recommendations.
  • Hawaii Volcanoes National Park and a major highway closed temporarily due to hazardous falling debris.

Event overview

This event was described as the 43rd episode since the eruption phase began in December 2024, and live streams showed two bright red lava fountains and a column of smoke above the summit crater.

Crater confinement

Reporters and officials emphasized that the molten rock remained confined within Kilauea’s summit crater in Hawaii Volcanoes National Park.

Across accounts, it was noted that the lava did not threaten homes or buildings, even as the eruption produced hazards outside the crater.

Closures and shelter

Falling ash and glassy volcanic fragments (tephra) forced temporary closures inside the national park near the summit and prompted a partial closure of Highway 11.

A new eruption of the Kilauea volcano triggered an ash-fall warning in Hawaii on Tuesday, affecting residents and visitors in several communities near Hawaii Volcanoes National Park

Hawaii County opened a shelter at a district gymnasium for affected residents and tourists, but officials reported no one was using it shortly after it opened.

Ashfall risks

The National Weather Service issued an ashfall warning and predicted more than a quarter-inch of accumulation in parts of the park and surrounding areas.

Officials cautioned that tephra can irritate eyes, skin and the respiratory system and can also clog water catchment systems used in parts of the Big Island.

Eruption variability

Observers stressed that Kilauea’s fountaining episodes vary widely in duration, with some events lasting hours and others lasting days.

Reports highlighted the large volumes of lava produced during this eruptive phase, noted uncertainty about how long the activity will continue, and described Kilauea as one of the world's most active volcanoes.
