Most Pacific Rim countries participate in an advanced tsunami warning system—but when the 2004 Indian Ocean tele-tsunami struck, no such system existed for that region. This program recounts the events of the disaster and explores the potential for more occurrences like it—including scenarios involving vast destruction in the United States. Following a country-by-country breakdown of the 2004 tragedy, the video shows how landslides can cause tsunamis of almost unimaginable power, how such a collapse in the Canary Islands could swamp America’s East Coast, and how a truly global tsunami warning system might be established.
