It's a complete and good illustrated textbook on all points of tsunami. i don't believe there's the other booklet at the subject released. As one bookseller acknowledged after the Indian Ocean tsunami occasion, "I might have simply crammed my entrance window with copies and they'd have walked out the shop.
