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.

Episodic eruption at Kīlauea summit

Color photograph of lava fountain

This eruption is within Hawaiʻi Volcanoes National Park. Lava flows are contained to the caldera, but fallout from the lava fountains can affect communities downwind. 

Eruption Information

Is tephra falling? We want to know.

If you live in an area downwind of Kīlauea summit and are experiencing tephra fall, support science and community awareness by making a tephra fall report.

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. 

See map of current tephra fall reports
