Details for: Novarupta
A 65-m-high, 380-m-wide lava dome lies within a circular ejecta ring and caps the 1912 vent of Novarupta volcano. A 60-hour-long eruption beginning on June 6, 1912, the Earth's largest eruption during the 20th century, produced The Valley of Ten Thousand Smokes ash-flow deposit, which forms the flat ground at the right. The face of Falling Mountain, behind Novarupta dome, was sheared off by a 2-km-wide collapse around the Novarupta vent. This view from the NE shows snow-capped Mageik volcano in the background.
