A toddler could have plummeted to his death on Christmas Day at Hawaii's Kilauea volcano if not for his mother's quick reaction, officials said. The National Park Service said in a statement that the toddler wandered off from his family at the Kilauea Overlook and snuck past the barrier blocking onlookers from the volcano before running toward the 400-foot cliff edge.

The eruption of Kilauea volcano on Hawaii’s Big Island has stayed within the mountain’s summit caldera inside Hawaii Volcanoes National Park.

A boy, roughly 2 to 3 years old, ran into a closed area Wednesday at the Kilauea Overlook, coming within a foot from the edge of Kaluapele, the summit caldera, before his mother managed to pull him to safety.

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.

Kilauea, one of the world’s most active volcanoes, erupted early Monday on Hawaii’s Big Island, sending out glittering torrents of lava.
