Kīlauea Eruption of 2026

Official USGS photographs of lava fountains, an eruption plume, and tephra impacts at Kīlauea's summit in Hawaiʻi.

What Is Tephra?

Tephra is the scientific name for fragments of volcanic material thrown into the air during an eruption. It can range from fine ash to larger pieces. Wind can carry the smallest particles away from the vent, which is why scientists track plume height and direction.

How Scientists Monitor Kīlauea

Hawaiian Volcano Observatory scientists combine photographs with earthquake sensors, ground-deformation measurements, gas observations, and satellite data. Together, these measurements help researchers understand how magma moves and communicate changing hazards.
