Tephra from the September 2023 eruption — September 12, 2023

Detailed Description

On September 12, 2023, HVO geologists landed on the downdropped block to collect samples of tephra from the now-inactive easternmost fissures of the new eruption at the summit of Kīlauea. These samples will be analyzed to better understand how and why the new eruption occurred. USGS photo by K. Lynn.
