NOVA Season 15 Episode 6 Volcano!

In the NOVA season 15 episode 6, viewers are taken on a journey around the world to explore the awe-inspiring power of volcanoes. With stunning footage and expert interviews, the episode delves into the science behind these natural wonders and the impact they have on our planet.

The episode begins in Iceland, where viewers witness the explosive eruption of Mount Eldfell in 1973. The eruption completely devastated the town of Heimaey, but also provided scientists with valuable data on how volcanoes operate. From there, the episode takes us to Hawaii, where we see some of the world's most active volcanoes. Kilauea and Mauna Loa are studied by volcanologists, who gather information on the lava flow and gas emissions in order to predict eruptions.

Next, NOVA explores the phenomenon of super volcanoes, using the Yellowstone Caldera in Wyoming as an example. This supervolcano erupted 640,000 years ago, and scientists have discovered that it is still active. The episode explains that a future eruption could be catastrophic, potentially causing a global winter and mass extinctions.

The episode then takes viewers to the volcanic island of Montserrat in the Caribbean, where in 1995, Soufrière Hills erupted, forcing the evacuation of the majority of the island. The episode tells the story of how the island's inhabitants coped with the aftermath, and how scientists are using the data gathered from the eruption to improve prediction models for similar events.

NOVA also explores the impact of volcanic ash on airplane engines and the potential for air traffic disruption. The episode explains how planes were grounded all across Europe during the eruption of Iceland's Eyjafjallajökull volcano in 2010. The episode takes us inside an engine testing facility to see how scientists simulate the effects of volcanic ash on airplane engines.

The show concludes by reminding viewers that volcanoes are a potent reminder of the power of nature and the unpredictability of the planet we live on. However, it also gives viewers an appreciation for the dedicated scientists who work to monitor and understand these phenomena in order to keep us safe.

Overall, NOVA season 15 episode 6 is a fascinating exploration of one of nature's most captivating forces. With stunning visuals and expert insights, viewers will come away with a new understanding and appreciation for the science of volcanoes.
