Fountains from the north vent are now approximately 1000 feet (305 meters) high. Volcanic ash, pumice, and Peleʻs hair are being blown to the south-southwest of the vent. View All Messages.

High fountaining began at 5:15 AM with lava fountains from the north vent growing rapidly from 100 feet (30 meters) to 600-700 feet (200 meters) by 5:30 AM. Based on previous eruptions, lava fountains may exceed 1000 feet during episode 28. View All Messages.

Sustained lava fountains from the north vent are now up to 150 feet (50 meters) high and feed a vigorous flow on the floor of Halemaʻumaʻu, High fountains are expected to begin soon as degassed magma is cleared from the vent. View All Messages.

Episode 28 of the ongoing Halemaʻumaʻu eruption began with low fountains and lava flows from the north vent at 4:10 AM on July 9th. Fountains are currently about 100 feet (30 meters) high but are expected to grow quickly. View All Messages.

At 6:15 p.m. HST on July 7, brief and minor overflows began from the north vent in association with gas piston cycles. These cycles are a common occurrence as summit inflation pushes lava closer to the surface within the vent conduit. View All Messages.

HVO monitors earthquakes and the active volcanoes in Hawaii, assesses their hazards, issues warnings, and advances scientific understanding to reduce the impacts of volcanic eruptions. Communicating the results of our work to the public, emergency managers, and the scientific community is an important aspect of the HVO mission.
