Introduction: Journey to Fire Mountain: Part 1 (01:27)
This film presents Mount Yasur in Vanuatu, Australia, a mountain that's been erupting for over 300 years.
Mount Yasur (02:52)
Vanuatu is home to a volcano that erupts day and night. Inhabitants call this volcano Yasur, "the old man." It has been erupting on and off for 300 years.
Lava Bombs (04:43)
Big explosions of the volcano are followed by a shock wave. Scientists attempt to get a fresh lava bomb. Much can be learned from studying the chemistry of fresh lava.
Son of the Volcano Spirit (05:43)
Humble and her crew wake to find a plumb of gas spiraling out of the volcano. They question inhabitants about the experience of living next to an active volcano.
Monitoring Sulfur Levels (02:02)
The amount of sulfur in the gas emitted by Mount Yasur might help scientists predict if the eruptions will become more violent.
Inhabitant's Culture (02:39)
Vanuatu inhabitants see pigs as a sign of wealth and status. In 2006, Vanuatu was named the happiest nation on Earth.
Radiant Heat (04:00)
Scientists set-up a camera that captures radiant heat from the heart of the mountain. Every volcano has a particular chemistry. Timing volcano blasts allows for a safe extraction of a fresh lava bomb.
Farming in Vanuatu (03:32)
Taro root is a good crop to grow when living near a volcano. The ash slides off its large leaves. The erupting ash brings the benefit of soil full of minerals.
History of Mount Yasur (03:18)
Layers of ash, preserved by a quickly drained lake, reveal the history of Mount Yasur over the last 400 hundred years.
Evidence of Cataclysmic Eruption (02:39)
A massive and violent eruption of Mount Yasur is evident from the formation of a large, red cliff known as a caldera. If any eruption of the same magnitude occurred again, no one would survive on the island.
Waiting for a Lava Bomb (03:59)
Humble and her team wait for the proper timing to recover a lava bomb. They have two minutes from when the bomb has landed to recover it and get back to a safe distance.
Mount Yasur Throws a Bomb (04:00)
Yasur erupts a lava bomb that is the right size and distances from the scientists. They prepare for the extraction of the bomb.
Collecting a Lava Bomb (04:16)
Humble's team strike at the opportunity of collecting a lava bomb just in reach.
Scientific Observation (02:14)
Humble and her team discover a low amount of zirconium in the fresh lava bomb collected, indicating a low level of threat from a massive eruption of Mount Yasur.
