The 24th eruption episode has begun at Kilauea – lava fountain 300 m high
Hilo, June 5, 2025
Hawaiʻi’s Kīlauea volcano has erupted again: the 24th eruption of the current phase, ongoing since December 23, 2024, began overnight. A lava fountain over 300 meters high shot lava up to the rim of Halemaʻumaʻu crater, while large lava flows now cover its entire floor.
The eruption started on June 4 at around 9:15 PM HST (07:15 UTC, June 5), with initial fountains reaching about 30 meters. By 10:27 PM HST, activity had intensified significantly, with fountains reaching 150 meters — and shortly after, exceeding 300 meters. The main activity is from the northern vent, while the southern vent is producing a smaller, 50-meter-high fountain.
Warning signs appeared in the afternoon, with intermittent lava spattering. A lava flow began shortly before the fountain activity — a typical paroxysmal pattern, also seen recently at Etna and Fuego.
Significant ground inflation of about 12 µRad was recorded after the previous eruption on May 26 — one of the highest values since episodic activity resumed, indicating a strong paroxysm with potential for further escalation.
Authorities are closely monitoring the situation. While there is currently no direct threat to the public, visitors to Hawaiʻi Volcanoes National Park are strongly urged to stay within designated safety zones.
