The Orphan Tsunami of 1700 details a mysterious tsunami in Japan in January 1700, with no parent earthquake felt. Unveiling this scientific mystery took until the 1990s, with discoveries in both North America and Japan. The book explores how this orphan tsunami was finally linked to an earthquake off the coast of northwestern North America through a series of extraordinary events. The second edition of the book sheds light on the precautions taken against earthquakes and tsunamis in the Cascadia region today. The story parallels the Japanese tsunami of March 2011, highlighting the importance of understanding historical natural disasters.
