As the world woke up to news of a massive earthquake, a silent killer was racing across the Indian Ocean at the speed of a jet airliner. In this episode, Dr. Zand van Tulleken and Raer Dave explore the terrifying physics of the 2004 tsunami as it reached Sri Lanka and the Maldives. We investigate the "Second Wave" phenomenon—a dense, lethal slurry of debris and sewage that claimed lives long after the initial impact. Discover the remarkable science of infrasound, which allowed animals to sense the danger hours before humans, and learn why the unique geology of the Maldives saved it from total atoll destruction. From the harrowing story of the "Ocean Queen" train disaster to the hunt for the world's first viral disaster footage, we piece together the timeline of a day that changed history.
