The Active Volcano in Alaska; Yantarni

Описание: Within Alaska are 86 active volcanoes. Despite producing a recent massive eruption, one of these volcanoes was unknown to science until 1979. Then, the Yantarni volcano was discovered alongside a large deposit of ash and volcanic debris. It produced a lateral collapse 2800 years ago in an eruption similar to the 1980 eruption of Mount Saint Helens. This video will discuss this volcano and mention what its future hazards are.
