In 1912, the Novarupta volcano, located on the Alaska Peninsula, erupted, ash from which still covers its slopes.
And strong northwestern winds blowing in the area of the Katmai National Park and Nature Reserve along the “Alley of tens of thousands of smokes” blow away this ash and carry it towards the Kodiak Island, which lies 100 miles to the southeast. According to experts, the ash cloud will not rise higher than 7000 feet, and therefore may pose a danger to aircraft flight, as the Federal Aviation Administration has warned about. In addition, some of the ash can settle in settlements lying in the path of the cloud.
The eruption of Novarupta volcano – one of the largest in the history of the country – began on June 6, 1912 and lasted three days. Ashes from the volcano’s vent rose to an altitude of 100,000 feet and erupted magma reached 3.6 cubic miles, which the Federal Geological Survey estimates 30 times more than the eruption of Mount St. Helens 40 years ago in Washington state. Sedimentary rocks from solidified magma in parts of the Tens of Thousand Smokes Alley are up to 600 feet deep.
