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 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.

Mother saves toddler from 400-foot fall at Hawaii’s Kilauea volcano. Park officials urge safety near closed areas and trails.

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.

As thousands more visitors descend upon Hawaii Volcanoes National Park to view Kilauea erupting, the park warns people to take safety precautions.
