The latest lava fountaining episode of an erupting Hawaii volcano reached 1,000 feet high Tuesday, prompting temporary closures at a national park and part of an important highway because of falling glassy volcanic fragments, including ash. Kilauea, on Hawaii's Big Island, has been dazzling residents and visitors for more than year with an on-and-off eruption that periodically sends fountains of lava soaring into the sky. The fountaining that began Tuesday morning marked the eruption's 43rd episode since it began in December 2024.
