Although I have heard about the tsunamis in the Indian Ocean, I was never aware of all the details and the effort going on the predict and warn of future events. Just the shear number of earthquakes, tsunamis, etc. that occur without us knowing about them is amazing. All the cases described in this book about tides, waves, etc. show how important the sea has been throughout history. If you have ever had any interest in history and/or the sea, read this book.
