The series investigates the complex geological science behind these massive waves, from the underwater earthquakes to the volcanic eruptions that trigger them. Viewers are taken to the front lines where scientists work tirelessly to improve early-warning systems that can save thousands of lives. Combining cutting-edge CGI with gripping first-hand accounts from survivors and dramatic archival footage, the show highlights the critical moments between a seismic event and a tsunami's landfall. This compelling examination of science and human survival has ended, but sign up for a reminder just in case it returns. It remains a powerful look at our race against the clock.
