March 10, 2026 — Kīlauea episode 43 eruption plume

The dual fountains that erupted during Kīlauea summit eruption episode 43 on March 10, 2026, produced significant heat and ash, creating an eruption plume. The plume reached 10,000 feet (3050 meters) above sea level at 10:10 a.m. HST, over 20,000 feet (6100 meters) by 11:30 a.m. HST, and over 25,000 feet (7600 meters) above sea level by 10:50 a.m. HST. The maximum plume height exceeded 30,000 feet (9100 meters) above sea level by 11:30 a.m. HST. Light southwest winds at lower elevations pushed the plume and tephra fall to the north and east. This photograph, which looks toward the summit of Kīlauea, shows the plume traveling overhead. USGS photo.
