A summer view of Katmai Pass extends to Novarupta volcano The eruption that transformed Southwest Alaska [By Andromeda Romano-Lax] A hundred years ago, on a hot and windless June day along the Katmai coast, a strange snow began to fall. The explosive outburst at Novarupta (Alaska) in June 1912 was the 20th century's most voluminous volcanic eruption. - Composite volcanoes or stratovolcanoes: ... June 6, 1912 - Novarupta volcano erupts in Alaska, killing two people. Moreover, they can range anywhere from 1-10 km in diameter. Composite volcanoes are also known as strato volcanoes. 3. It was so powerful that it drained magma from under another volcano, Mount Katmai, six miles east, causing the summit of Katmai to collapse to form a caldera half a mile deep. Death and property damage aren't the only consequences of composite volcanoes. The volume of volcanic ash from Novarupta was more than from all other historical Alaska eruptions combined. Particulates released by composite volcanoes yield colorful sunrises and sunsets. The largest volcanic eruption of the 20th century occurred near Katmai volcano, a stratovolcano with a caldera near its summit. Novarupta, the least topographically prominent volcano in the Katmai area, was formed during a major eruption in 1912. Because they eject matter and gases into the stratosphere, they affect weather and climate. It is a very young volcano at this point, just over 100 years old. No. At the time of the eruption little was known about the area. (VEI 6) Banded pumice colors the Valley of 10,000 Smokes in Katmai National Park in Southwest Alaska. Novarupta-Katmai Ash Resuspension. On June 6th, 1912, Mount Katmai/Novarupta erupted on the Alaska mainland, just 250 miles (402 kilometers) southwest of Anchorage. Katmai Volcano – Novarupta volcano vent. 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. Examples of composite volcanoes: Mount Fuji, Mount Shasta, Mount St. Helens, Mount Rainier. Semeru Volcano in Indonesia is an active stratovolcano. Resuspended volcanic ash should be considered hazardous and could be harmful to aircraft and health. It is just a caldera and a lava dome, so there is no Mount in Novarupta. Ash from seven prehistoric eruptions, all younger than 6,000 years and approaching the volume of the 1912 event, are found within 500 miles (800 km) of Anchorage, including ash from Hayes volcano (Bacon, et al., 2012) (Public domain.) Composite Volcanoes. It is the largest volcanic eruption of the 20th century. This eruption was the world's largest during the 20th century and produced a voluminous rhyolitic airfall tephra and the renowned Valley of Ten Thousand Smokes (VTTS) ash flow.
