James Brooks, city editor of the Juneau Empire and author of 9.2: Kodiak Island and the World's Second-Largest Earthquake, talks on four natural and manmade disasters in Alaska. Through the 1912 Katmai-Novarupta volcanic eruption, the 1925 Nome Serum Run, the 1964 Good Friday Earthquake, and the 1989 Exxon Valdez Oil Spill, we get a picture of how the state of Alaska changed throughout the 20th century.
