This video segment from Nature features Hawaii’s most notorious volcano, Kilauea. Over 10,000 years ago, Kilauea emerged from a hotspot on the ocean floor and began a journey that continues today. This active volcano has made The Big Island the largest in the Hawaiian island chain. In 1983, a vent called Pu’u O’o developed. When the vent erupts, red hot molten lava can explode 1,000 feet into the air, with a sound that is deafening.
