Photo & Video Chronology — April 9, 2026 — Kīlauea summit episode 44

kmulliken@usgs.gov — Thu, 9 Apr 2026 22:19:28 EDT

Episode 44 of lava fountaining at the summit of Kīlauea took place on April 9, 2026. Southerly/southwesterly winds resulted in the plume being transported in the north/northeast direction, resulting in tephra falling in areas of Hawaiʻi Volcanoes National Park, on Highway 11 nearby, and on communities near the summit of Kīlauea.
