Episodic 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.
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?
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.
