Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.

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

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.
