Description


Investigating past volcanic eruptions helps geographers to understand future risks to people and the environment. In this video, we team up with Dr. Joanne Egan, to explore the impact of ash from the eruption of Mount Mazama 7,600 years ago, one of the largest eruptions in North America in the past 10,000 years. We discover how ash affected environments and ecosystems across North America, and imagine what a similar event today might mean for society.
