Kīlauea eruption sends 1,000-foot lava fountains skyward in fiery spectacle, 23rd episode since December

Hawaiʻi's Kīlauea volcano erupted again on Sunday, May 25, sending lava fountains soaring over 1,000 feet into the sky. This marks the 23rd episode of the ongoing eruption that began in December 2024.

The eruption was confined within Halemaʻumaʻu crater at Kīlauea's summit, with lava flows covering portions of the crater floor.

Kīlauea's current eruptive phase has been characterized by episodic activity, with eruptions lasting from several hours to a few days, interspersed with periods of relative calm. The previous episode began on May 16 and lasted approximately 10 hours.

The eruption commenced at 4:15 pm HST, with the north vent initiating sustained lava fountains that escalated to impressive heights by 4:50 pm. The south vent followed suit at 5:15 pm, producing smaller fountains. By 5:20 pm, the north vent's fountains exceeded 1,000 feet (approximately 300 meters), while the south vent's reached about 230 feet (70 meters).

This eruption is part of a series of episodic activities at Kīlauea's summit, specifically within the Halemaʻumaʻu crater. Since the onset on December 23, 2024, the volcano has exhibited a pattern of eruptions lasting from several hours to a few days, interspersed with periods of relative calm.

The Hawaiian Volcano Observatory (HVO) reported that the north vent ceased erupting at 9:48 pm, followed by the south vent at 10:25 pm. Despite the cessation of active fountaining, the vents and cooling lava flows continue to emit a glow, captivating observers.

While the visual spectacle draws attention, officials remind the public to stay informed through official channels and adhere to safety guidelines when visiting Hawaiʻi Volcanoes National Park.

Kīlauea, one of the world's most active volcanoes, has a long history of eruptions. Its activity is closely monitored by the U.S. Geological Survey's Hawaiian Volcano Observatory to ensure public safety and provide timely updates.
