Kīlauea volcano's summit eruption, within Hawai‘i Volcanoes National Park, began one year ago—on September 29, 2021. This three-minute video, produced by the Hawaiian Volcano Observatory, features footage from the past year and summarizes the eruption.

 

On September 29, at 3:30 pm HST, three fissures opened within Halemaʻumaʻu crater. The new fissures generated lava flows on the surface of a previous lava lake surface, creating a new lava lake eventually growing to nearly 300 acres in size. Over the next 14 months, lava flows continued to fill in the crater, ultimately effusing over 29 billion gallons of lava and raising the crater floor to nearly 500 feet higher than before the eruption. Although the eruption experienced 24 short term pauses, an active portion of the lava lake was almost always visible making for ideal viewing from several caldera overlooks for over a year.
