Spectators look on as Hawaii's Mauna Loa erupts

STORY: Mauna Loa began erupting on Sunday (November 27) for the first time since 1984, ending its longest quiet period in recorded history.

Mauna Loa rises 13,679 feet (4,169 meters) above the Pacific Ocean, part of the chain of volcanoes that formed the islands of Hawaii. It last erupted in March and April of 1984, sending a flow of lava within 5 miles (8.05 km) of Hilo, the island's largest city.
