'Looking into the heart of Kilauea'
The Kilauea volcano in Hawaii's Volcanoes National Park is considered to be one of the most active volcanoes in the world.
The volcano has been erupting consistently since March 2008 and has a lava lake, within the Halema'uma'u Crater, which measures an estimated 750ft (228m) across.
The Volcanoes National Park is an Unseco World Heritage Site and celebrates its 100 birthday this year.
