Ground tilt and eruptive episodes associated with Kīlauea summit eruption December 23, 2024, to January 10, 2025

Detailed Description

Ground tilt and eruptive episodes associated with Kīlauea summit eruption December 23, 2024, to January 10, 2025. Eruptive episodes are highlighted in red. Fountain Episode 1 (E1) began at 2:20 a.m. HST on December 23, 2024, and continued until 4 p.m. that day (14 hours duration).​ Fountain Episode 2 (E2) began at 8 a.m. HST on December 24, 2024, and continued until 11 a.m. HST on December 25 (15 hours duration). ​Fountain Episode 3 (E3) began at 8 a.m. HST on December 26, 2024, and continued until 8:30 p.m. HST on January 3, 2025 (8 and a half days duration).​ Assuming the eruptive vent(s) remains open, indicated by continued glow and degassing, and inflation rate remains constant, a new episode could potentially begin sometime between January 8 and January 13, when ground tilt at Uēkahuna is expected to reach 12 microradians, about double prior post-fountain tilt increases.
