Lava fountains at the Halemaʻumaʻu north vent currently measure about 150 meters (500 feet) in height, slowly diminishing in vigor since the early maximum of approximately 240 meters (800 feet) around 1:00 p.m. HST. 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.

Episode eruption at Kīlauea summit

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.

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.
