Скачать или смотреть Myanmar's Forgotten Active Volcano; Mount Popa

Myanmar is a nation known for many things, but volcanoes are not one of them. And yet, a mere 8,000 years ago a highly destructive eruption occurred at a stratovolcano known as Mount Popa. This video will discuss this ancient eruption, the debris avalanche it created, along with the age and geologic setting of this largely forgotten volcano.
