Kilauea, one of the world’s most active volcanoes, erupted early Monday on Hawaii’s Big Island, sending out glittering torrents of lava. The U.S. Geological Survey said its Hawaiian Volcano Observatory spotted signs of an eruption in the Hawaii Volcanoes National Park around 2:30 a.

Molten rock began shooting from the volcano before dawn on Monday when fissures opened in the caldera floor and propelled lava 295 feet (90 meters) into the air. The red liquid formed tall fountains and then spread across 650 acres (263 hectares). The Hawaiian Volcano Observatory estimated the lava was about 1 yard (1 meter) thick.

Hawaii’s Kilauea, one of the world’s most active volcanos, fired out partially molten “lava bombs” from its vents and lava fountains up to 262 feet.
