Those include Tsunami, which examines the details of the 2004 natural disaster in Southeast Asia, and Costa Concordia, about one of the worst maritime disasters in living memory; in addition to World War II-focused documentaries Countdown to War and The Great Escape. All of the series will air in 2021, with episodes shown on consecutive days of the week. Tsunami (3 x 60 minutes) will track the natural disaster that struck shorelines across Southeast Asia on Boxing Day in 2004, claiming 230,000 lives, including 149 Brits. The three-part series will incorporate scientific methods to explain how one of the largest earthquakes ever recorded gave rise to the deadliest tsunami in history, with each episode tracing the course of its devastating impact and lasting aftermath for survivors, hour-by-hour.
