May 21, 2025 — Kīlauea flaming vent

Detailed Description

Kīlauea summit livestream camera viewers have recently observed flames within the vents in Halemaʻumaʻu. These flames, which are often a yellowish orange color result from hydrogen gas burning in air. Hydrogen is a minor component of volcanic gas released from the hot magma below, and it can sometimes be ignited causing the flames observed recently. USGS photo by M. Cappos.
