The Kilauea volcano, located in Parque Nacional of Vulcões of Havaí, in Estados Unidos, recorded a new eruption from the night of November 16, 2025. The lava jets reached a height of more than 450 meters and formed columns with the appearance of horns, according to records from Serviço Geológico of Estados Unidos (USGS). The episode marks the volcano’s 37th eruptive activity since December 2024.
The current eruption surpasses in intensity the previous episode, which occurred on November 9, when the lava fountains reached 335 meters. Até At the moment, there are no records of damage to structures or the need to evacuate residents in the Havaí island region.
Activity recorded at the summit
The USGS confirmed that the eruption began in the Halemaumau caldera, at the summit of Kilauea. Imagens captured by cameras and observers showed multiple lava sources active simultaneously.
Luminescence was observed at the north and south openings of the crater at night. Peaks of seismic shaking occurred at intervals of five to ten minutes.
Jet height and shape
The lava fountains exceeded 450 meters in height at several times. The shape of parallel columns resembling horns was recorded in videos posted on social media.
- Estimated maximum height: above 450 meters
- Comparison with previous episode: increase of around 115 meters
- Main location: cracks in the floor of the Halemaumau boiler
- Duration of the most intense jets: intermittent periods throughout the morning
