Kilauea Eruption Sends Football-Sized Rocks Across Hawaii, 30,000-Ft Ash Plume Triggers Volcano Warning

Football-sized volcanic rocks are raining down on Hawaii.

Kīlauea volcano roared back to life on Tuesday morning, shooting lava fountains over 1,300 feet into the sky and forcing the US Geological Survey to issue its highest alert level. Episode 43 of the ongoing Halemaʻumaʻu summit eruption began at 9:17 a.m. local time on 10 March 2026, with an ash plume climbing to 30,000 feet above sea level, nearly double the typical height of previous episodes.

This is the first time since the current eruptive cycle began on 23 December 2024 that the USGS has raised the volcano alert level to Warning, the top of its four-tier scale. The aviation colour code now sits at Red.

43 Eruptions in 77 Days

Kilauea has now erupted 43 times since late December 2024. That works out to roughly one eruption every 1.8 days. Most episodes last less than 24 hours, but their frequency and growing intensity have kept scientists and residents on edge.

Episode 43 is more severe than most. Previous eruptions typically sent ash plumes to 15,000 or 20,000 feet. This one hit 30,000. The lava fountains from both the north and south vents peaked above 1,300 feet, or about 400 metres.

'Fallout up to football size pieces and smaller are reported at overlooks in Hawaiʻi Volcanoes National Park, creating hazardous ground conditions,' the USGS stated in its official notice.

Roads Closed, Schools Shut

The fallout is not limited to the national park. Residents in Volcano Village and Mauna Loa Estates reported tephra fragments up to three inches in diameter hitting their properties. The glassy volcanic debris can irritate skin, eyes, and lungs.

Highway 11, the main route connecting communities around the park, is now closed between mile markers 24 and 40. That cuts off a major transit link for thousands of residents and visitors.

Hawaii County opened an evacuation shelter at Kaʻū District Gym in Pāhala for anyone displaced by road closures or falling debris. All three Volcano School of Arts & Sciences campuses will stay closed on Wednesday for tephra cleanup, with all after-school programmes cancelled.

The National Weather Service extended an ashfall warning until 11 p.m. Tuesday for the park and communities to the southeast and southwest. Areas to the northeast, including Glenwood, Mountain View, Keaau, and Hilo, remain under an ashfall advisory.

What If You Had Travel Plans?

For anyone planning to visit the world's most active volcano, the timing is bad. Hawaii Volcanoes National Park has closed areas around Kīlauea's summit. Only guests at Volcano House and Kilauea Military Camp can enter, and they must shelter in place with proof of reservation.

Volcanic gas emissions, mainly sulphur dioxide, continue to drift downwind. The resulting vog, or volcanic air pollution, poses health risks for children, the elderly, and anyone with breathing problems.

Why Kīlauea Keeps Erupting

Scientists say a surge of volatile-rich magma has been rising from beneath the summit since December 2024. According to NASA's Earth Observatory, this magma contains more dissolved gases, causing it to erupt more explosively. Think of it like shaking a bottle of fizzy drink and then popping the cap.

The episodic pattern, short bursts of intense fountaining followed by pauses lasting days or weeks, has allowed volcanologists to build predictive models. But Episode 43 shows the limits of those forecasts. The USGS had projected a window between 10 and 14 March for the next eruption. Kīlauea hit the early end of that range, and it hit hard.

Earlier this year, Episode 41 dumped what park officials called 'an unprecedented amount of tephra and ash' on roads, trails, and rooftops around the summit. Episode 43 appears to be following the same pattern, but worse.

What Happens Next

Lava flows have so far stayed within Halemaʻumaʻu crater and the southwest side of Kaluapele, Kīlauea's summit caldera. No residential areas face an immediate lava threat. But the tephra, the gas, and the road closures are already disrupting daily life across Hawaii's Big Island.

Residents and visitors should monitor updates from the USGS Hawaiian Volcano Observatory and Hawaii County Civil Defense. The situation is still evolving.

Football-sized rocks are still falling. And Kīlauea shows no sign of slowing down.
