New Findings from Mt. Fuji's Past Eruptions
Mt. Fuji is a symbol of Japan that has long-fascinated people with its beautiful, well-proportioned shape. However, it's also an active volcano that has erupted about 180 times over the past 5,600 years. The most recent one was more than 300 years ago, the Hoei eruption of 1707, and experts anticipate that another eruption could occur again before long. In 2021, the Mt. Fuji eruption hazard map was revised for the first time in 17 years, thanks to new findings by researchers studying the past eruptions. In this episode, we'll tag along with one researcher that discovered how the Hoei eruption altered both the mountain and its surrounding environs, and also revealed new clues about pyroclastic flows, as we learn about the latest research on Mt. Fuji's eruptions.
