Lava fountaining resumed at Kilauea’s summit this morning as a new eruptive episode began inside Halemaumau crater, prompting the Hawaiian Volcano Observatory to keep the volcano at watch alert level and aviation color code orange.
From USGS Hawaiian Volcano Observatory livestreaming V2cam, a plume-like fountain erupted from the north vent during episode 24 on June 4–5, 2025, creating an elegant arc. With a maximum fountain height of 364 meters (1194 feet), this was the highest fountain observed up until that point. USGS photo.
The Kīlauea summit has inflated by 23 microradians since the end of Episode 39 on Christmas Eve, Dec. 24, 2025, including an increase of at least 1.3 microradians within the past 24 hours. Slight deflation happened at about 5 a.m. today when the south vent overflowed, then increased somewhat at 7 a.m. when both vents became active.
Mount Etna is Europe’s most active volcano and the continent’s largest. It attracts hikers and backpackers to its slopes, while less adventurous tourists can take it in from a distance, most stunningly from the Ionian Sea.
Kīlauea summit region shook for 5 hours Nov. 14 that year as magma made a path to the surface. The eruption began at 8:08 p.m. as a series of small lava fountains on the south wall of Kīlauea Iki Crater, east of Kaluapele — the summit caldera of Kīlauea. Gradually, during the next day, eruptive activity became focused at one vent.
An earthquake swarm 35 miles (55 kilometers) beneath Kilauea in August 1959 was followed in October by ground swelling indicating that magma was accumulating within the volcano.
HONOLULU — Hawaii's Kilauea volcano resumed erupting Friday by shooting an arc of lava 100 feet (30 meters) into the air and across a section of its summit crater floor. It was Kilauea's 31st display of molten rock since December, an appropriately high ...
