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.

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.

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.

One of the world's most active volcanoes sprang into life again Monday, spewing columns of lava 80 meters (260 feet) above Hawaii, US vulcanologists said."At 4:30 am, lava fountains were observed with heights up to 80 meters (262 feet),

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 thick.
