Kīlauea Summit Eruption Episode 31 Produces Lava Fountains and Elevated Gas Emissions
Kīlauea’s summit erupted during Episode 31, delivering dramatic lava fountains that were visible in afternoon light from the northwest caldera rim. Viewers observed an inclined lava fountain rising from the northern vent, accompanied by the eruptive plume stretching above the crater.
During eruption episodes, sulfur dioxide emissions are known to rise. In this instance, winds were blowing from the northeast at 15-20 mph (about 8 meters per second), carrying volcanic gases to the south and southwest of the summit caldera.
What this means and why it matters: The ongoing activity at Kīlauea’s summit offers valuable data for scientists monitoring volcanic behavior and refining eruption forecasts. The south- and southwestward transport of gases due to prevailing winds can impact air quality downwind, so residents and visitors should stay informed and follow safety advisories.
Commentary and outlook: Continued gas and lava activity underscores the importance of vigilant monitoring. With real-time data on plume direction and gas emissions, scientists can better model future eruptions and communities can receive timely warnings to minimize health and safety risks.
Summary: Episode 31 showcases persistent summit activity with visible lava fountains, a steady eruption plume, and gas emissions shaped by northeast winds, highlighting the ongoing need for careful observation and public safety measures.
