Kilauea began a new episode of lava fountaining at its summit today, prompting an ashfall advisory for parts of Hawaii Island.

The Hawaiian Volcano Observatory said Episode 46 started at 8:17 a.m. inside Halemaʻumaʻu crater, with activity confined to Hawaii Volcanoes National Park.

The volcano remains at watch alert level and orange aviation color code, indicating heightened unrest with increased potential for eruption hazards.

The National Weather Service issued an ashfall advisory through 8 p.m. for areas downwind of the summit, including Volcano and Mountain View.

Light and variable winds shifting southeast are expected to carry volcanic gas and ash across the summit region and toward the north and northwest areas.

Tephra, including ash and Pele’s hair, is most likely within about 3 miles of the vents, but lighter material can travel much farther.

Officials said impacts are expected to be limited, though ash particles can irritate eyes and lungs, especially for those with respiratory conditions.

Residents are urged to limit exposure by staying indoors when possible, closing windows and doors and wearing masks and eye protection if going outside.

People with water catchment systems should cover and disconnect them to prevent contamination.

Anyone observing ashfall is encouraged to report conditions to the Hawaiian Volcano Observatory at hawaiiash.science/report_form.
