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.

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 (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.

The National Park Service says the boy was just about a foot away from a fatal fall when his mother snatched him up

Those who ignore the warnings, walk past closure signs, lose track of loved ones, and sneak into closed areas to get a closer look do so at great risk,” officials said.

Lava is bubbling through the crust of one of the world’s most active volcanoes, which is Kilauea, on Hawaii’s Big Island.

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