Episode 45 lava fountains have been "wispy" at the top, making it difficult to consistently measure maximum fountain heights. More accurate height estimates will be determined in the coming days after analysis of monitoring imagery. View All Messages.

Due to north/northeasterly winds, no significant tephra fallout has been reported at open areas of Hawaii Volcanoes National Park or on county roads. But small particles could be transported to communities farther downwind to the southwest. View All Messages.

Winds have been light from the north and northeast so tephra and gases have been blown to the south and southwest of Halema'uma'u. 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.

Where has tephra fallout been reported?

Color map showing area of volcanic fallout

Tephra is material erupted from a volcano that travels through the air. Volcanic ash, Pele's hair, and other tephra have fallen on communities downwind during lava fountaining episodes at the summit of Kīlauea.
