Kilauea volcano erupts: See the 660-foot lava fountain

How high can lava shoot? At Kilauea volcano on Hawaii’s Big Island, it hit 660 feet on Thursday, sending a plume soaring 18,000 feet above sea level. See how much lava poured out of Halemaʻumaʻu crater over about six hours in the 56th fountaining episode since the eruption began in December 2024.

Volcano Watch: Such great heights; measuring Kīlauea’s lava fountains

“Volcano Watch” is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates.

Volcano watchers keep coming back to that single question once lava fountains start at KÄ«lauea, and there have been plenty of opportunities to ask as we’ve now had 56 fountaining episodes during the past 2 years at the volcano’s summit.

Some of these fountains peaked fairly low (a little higher than about 300 feet), but some have been absolutely towering (higher than about 1,500 feet). Episode 56 fountains on Nov. 5 reached at least about 660 feet.

So how do Hawaiian Volcano Observatory geologists actually measure fountain height?

Why has Mount Kilauea been erupting for so long?

Lava fountains reached about 660 feet, roughly the height of a 60-story building. It was episode 56 in an eruption that began just before Christmas in 2024, nearly two years ago.

That’s a long run for a Kilauea summit eruption, considering some recent events only lasted a few weeks. Scientists think this one has settled into a kind of equilibrium: pressure builds in magma reservoirs beneath the summit, then lava fountains release it.

And Kilauea has had even longer eruptions. A separate eruption at Puu Oo, on the volcano’s East Rift Zone, lasted 35 years.

So decades of activity are possible, though that was in a different part of the same volcano.
