Kodiak Island had a somewhat unique Winter Warning on Thursday. Mixed in the fresh snow was some ancient volcanic ash. Ash from the Novarupta eruption of 1912 was carried across the Shelikof Strait due to some high winds, and the ash came down with the recent snowfall. The ash was not expected to climb above 7000 feet, but airlines were notified, and air quality on the island may have been diminished.
The Novarupta eruption started on 6 June 1912, and lasted three days. The eruption was the most powerful of the 20th Century. The ash cloud is thought to have risen to over 100,000 feet, which is incredibly impressive. An estimated 3.6 cubic miles (15 cubic KMs) of magma erupted. That’s 30 times more than the Mount St Helens eruption. As much as 600 feet of ash was dumped on the region now known as The Valley of 10,000 Smokes.
The ash kick-up does happen from time to time, when winds hit the area just right, and carry loose ash over to Kodiak.
All seven volcanos in the Katmai region, including Novarupta, remain at Level Green.
