A major volcano on Hawaii's largest island roared to life, sending 'football-sized' debris into the air. The Halemaʻumaʻu Crater, part of the Kilauea Caldera, erupted with a plume of lava rising to 25,000 feet above sea level, the Hawaiian Volcano Observatory said. The park is now closed to the public, and visitors are urged to seek shelter indoors. #volcano #kilauea #hawaii #nature
