Kilauea Volcanoic Eruption Update

Episode 15 of the volcanic eruption concluded on March 26, 2025, leaving orange glow from cooling lava visible at night. The condition of the vents after this episode is notably different from previous eruptions. The south vent continues to degas weakly, while the north vent, largely filled with tephra and spatter, has been inactive and shows little glow, suggesting possible blockage. Overall, vent glow is much reduced compared to earlier episodes.

Tiltmeter measurements at Uēkahuna (UWD) and Sand Hill (SDH) recorded deflation during the eruption, followed by inflation during the pause. Seismic tremor decreased sharply after the eruption, though it returned intermittently on March 27 at lower levels.

Gas emissions, especially sulfur dioxide (SO2), remain elevated, but conditions like weak winds are causing lingering vog in the area, complicating measurement efforts. Additionally, volcanic glass (Pele's Hair) and small tephra chunks have been found around the summit and surrounding areas.
