Wednesday was the anniversary of the Novarupta eruption, the largest one of the 20th century. If' you've never heard of Novarupta, don't be surprised... I hadn't either, and I live in Alaska. Besides, like the famous eruption of Krakatoa in 1883 and Mt. Mazama, Crater Lake, the mountain doesn't really exist anymore since it blew it's top. It's now a national park better known as The Valley of 10,000 Smokes, and is still a volcanically active area, although not currently erupting.
Loving geology as I do, I still remember being impressed as a school child when I read about the huge eruption of Krakatoa and how the world's weather was influenced by all the ash ejected. None of the teachers that I had in school ever mentioned the Katmai eruption.
I never realized that the eruption was 30 times larger than the relatively recent eruption in 1980 of Mt. St. Helen's. It was loud enough to be heard in Juneau, 800 miles away and covered the island of Kodiak in a foot of ash.
I am so glad it happened in 1912 instead of now! I've had to clean up ash twice from two very small local eruptions, and I can't imagine dealing with deep ash fall.
