The Novarupta eruption is the strongest in the last century and among the largest in history
A wind is blowing ash from a volcanic eruption over Alaska in 1912, the Associated Press reported.
The unusual warning was issued by scientists, according to which the cloud headed to the island of Kodiak.
The ash is from the powerful eruption of Novarupta volcano on the Alaska Peninsula more than a century ago, but it is still visible.
Strong northwest winds in the vicinity of Katmai National Park and Reserve raised the remaining volcanic ash.
“At this time of year, these northwest winds appear, which can come from the Katmai area and clean up some of the ash left over from the 1912 eruption,” explains volcanologist Hans Schweiger.
The winds are expected to carry the ashes about 160 kilometers southeast to Kodiak Island. A warning has also been issued to the aviation industry. According to experts, the cloud will not rise to a height of more than 2133 meters.
The three-day Novarupta eruption, one of the world’s largest, began June 6, 1912, and sent ash as high as 100,000 feet (30,480 meters) above the Katmai region, located about 250 miles (402 kilometers) southwest of Anchorage. The U.S. Geological Survey estimates 3.6 cubic miles (15 cubic kilometers) of magma erupted, about 30 times what spewed from Mount St. Helens in Washington state 40 years ago.
