Ep 9. Killer Landslides

NOVA is a highly acclaimed science documentary series that seeks to explore some of the most fascinating and complex questions about science, technology, and the natural world. During its 42nd season, the show features an episode titled Killer Landslides, which delves into the scientific study of landslides in an attempt to understand these natural disasters more deeply.

The Killer Landslides episode is structured around a series of stories and interviews with scientists, researchers, and survivors of landslides. The episode begins with an interview with a man who survived the 2014 Oso Landslide, which killed 43 people and destroyed an entire community in Washington State. From there, the episode explores the different ways in which landslides can occur, and the different factors that contribute to their occurrence.

One key factor that the episode explores is the role of water in landslides. The show explains how landslides can be triggered by rainfall, and how saturated soil can make the land unstable. It also examines the different types of landslides that can occur, such as debris flows, rockfalls, and earthflows, and how each type is influenced by different factors.

Another important theme in the episode is the relationship between human activity and landslides. The show explains how human development, such as building on steep hillsides or altering the natural flow of water, can increase the likelihood of landslides. It also highlights the importance of building codes and standards to ensure that structures are safe during disasters.

Throughout the episode, viewers are treated to stunning footage of landslides occurring in different parts of the world. These visuals help to illustrate the power and destruction that landslides can cause, and also show the different ways in which people attempt to mitigate their risks. For example, the episode highlights the work of scientists who use lasers and other tools to study the terrain and predict where landslides might occur.

Overall, Killer Landslides is a fascinating and informative episode of NOVA that sheds light on a subject that is both complex and mysterious. With its mix of science, storytelling, and stunning visuals, viewers will come away with a deeper understanding of landslides and their impact, and will gain a new appreciation for the power and beauty of the natural world.
