United States - September 19, 2025 Hawaii, United States – Hawaii’s famous Kilauea volcano is erupting spectacularly during what scientists are calling "Episode 33," offering a dramatic display for residents and visitors on the Big Island. The Hawaiian Volcano Observatory (HVO) is closely monitoring the summit, where molten rock is rising and falling in dramatic cycles, a process known as "gas pistoning." This activity has caused small lava overflows and dome fountains shooting 10 to 20 feet high from the north vent within Halema’uma’u crater. Episode 33 marks the start of dramatic lava fountaining, part of an episodic pattern not seen since the legendary Pu’u ‘Ō’ō eruption in the 1980s. Scientists and volcano enthusiasts are watching closely as Kilauea puts on a mesmerizing and fiery show.
