I don't know if it is the one he is looking for but Night of the Howling Dogs is a great book! It is based on a true story of a Boy Scout troop in Hawaii. There is an earthquake that sparks a tsunami and mudslides. It has been awhile since I read it, but I think there is someone who dies. I think it was a troop leader or a guy they met on the trail. Even if it isn't the one he is looking for I bet be would like this one. It is one of the best middle reader books I've read in the last several years and I read a lot of them for a state book award committee that I am on. It is one of the books that I can remember vividly even years later.
