What had been low-level lava flows since Thursday morning became more vigorous fountaining Friday evening, according to the U.S. Geological Survey’s Hawaii Volcano Observatory.

One of the world's most active volcanoes spewed lava into the air for a second straight day on Tuesday. The eruption of Kilauea volcano on Hawaii's Big Island has stayed within the mountain's summit caldera inside Hawaii Volcanoes National Park.

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.
