The massive eruption had a decadal impact of wildlife, affecting the spawning of salmon in the rivers near Novarupta for years. The lava dome named Novarupta marks the vent of the 1912 eruption. real source of 1912 eruption 1950s Novarupta identified as the source of the eruption Scientists studying the eruption in the 1950s discovered that Novarupta Volcano was the source of the all the pyroclastic material. Le Novarupta est un volcan des États-Unis situé en Alaska, à proximité du mont Katmai. What is known as the Novarupta or Katmai eruption of 1912 was huge - ejecting almost 30 cubic kilometers of ash and debris into the atmosphere or along the ground as pyroclastic flows. Its violent eruption, which began on June 6, 1912, and lasted 60 hours, is Novarupta: Biggest Eruption of the 20th and 21st (so far) Centuries - Duration: 9:59. Novarupta is 1235 ft (380 m) wide and 211 ft (65 m) high. Novarupta, meaning "new eruption", is a new volcano that was created in 1912 and located on the Alaska Peninsula in Katmai National Park and Preserve, about 290 miles (470 km) southwest of Anchorage. The magnitude and volume of the eruption at Novarupta in 1912 were exceptional, far larger than any other historical eruption in North America (Figure 2). NPS photo by M. Fitz.

The eruption of Novarupta on June 6-8, 1912, produced an estimated four cubic miles (17 km3) of ash fallout (Fierstein and Hildreth 1992) and resulted in one of the most significant cooling events of the twentieth century (Briffa et). Photo by Jay Robinson, National Park Serive. The explosive outburst at Novarupta (Alaska) in June 1912 was the 20th century's most voluminous volcanic eruption. This fueled early U.S. Geological Survey and National Geographic Society scientific investigations that provided provocative perspectives and helped to shape thinking about volcanoes and magmas (Martin 1913, Griggs 1922). Because caldera collapse occurred 10 km from the vent, eruption deposits have been well The 1912 eruption that formed Novarupta was the largest to occur during the 20th century. Eruption and Deposits [8] The 1912 Novarupta eruption was the most voluminous eruption of the twentieth century. Novarupta-Katmai Ash Resuspension Resuspension and transport of fine-grained volcanic ash from the Katmai National Park and Preserve region of Alaska have been observed and documented over the past several decades, but has likely been occurring ever since the 1912 Novarupta-Katmai eruption. On the afternoon of June 6, 1912, a massive volcanic eruption occurred on the Alaskan Peninsula, across from Kodiak Island. The only new Novarupta is a volcano, located on the Alaska Peninsula in the Katmai area, about 290 miles southwest of Anchorage.Its eruption of June 6-June 8, 1912 was ten times more powerful than the 1980 eruption of Mount St. Helens and also lead to the formation of this 841 metre (2760ft) volcano..
