What is it like to witness a tsunami? How is its reporting and history formed from different people's perspectives of the event? This book uses first-hand accounts from eyewitnesses, survivors, the emergency services, scientists and the media to describe what happened before, during and after the tsunami that hit Japan in 2011. We also look at the science: the facts, the timeline and the physical causes and effects of the tsunami. Why was the disaster in Japan unique? How did it compare to other tsunamis? And how long will the clean-up take?
