My OperaLargest eruption in the 20th century

The largest volcanic eruption in the world in the 20th century occurred in 1912 at Novarupta on the Alaska Peninsula. An estimated 15 km3 of magma was explosively erupted during 60 hours beginning on 6 June 1912. At least seven eruptions of comparable size seem to have occurred within 800 km of Anchorage in the last 4,000 years.
How ready is the Kenai Peninsula to deal with a major eruption? Anchorage Daily News raised this question on 1 January 2006 at http://www.adn.com/news/alaska/ap_alaska/story/7326286p-7238370c.html
I would say that they could be better prepared, but read their story and make up your mind.

Novarupta is situated near the Alaskan-Aleutian plate boundary. This boundary is 4000 km long, and subduction along it has caused some of the largest earthquake ruptures on this planet. The great earthquakes of 1964, 1957 and 1965 are all M9 class events and rank globally among the six largest historic earthquakes. I mentioned in my log on Parent found for orphan tsunami that this is one out of only two regions in the United States where a huge Pacific tsunami could be triggered (the other being the Cascadia mountain range in the northwestern United States).
