Some disasters strike a place once and never return; others come back for a second round. This episode of Disaster Deja Vu pairs two of history's deadliest natural catastrophes: the Great Jiangsu Flood that drowned parts of China in 1931, and the Great Cyclone Disaster that tore through St. Louis in 1896. Using CGI reconstructions, archival photographs, and original film footage, the film rebuilds each event as it unfolded, tracking the rising waters along China's flood plains and the funnel cloud that ripped through Missouri's riverfront city. Narration lays out the death tolls, the property destroyed, and the conditions, from monsoon rains to unstable weather fronts, that made both regions vulnerable to catastrophe more than once in their history. The two disasters sit an ocean and several decades apart, but the film uses them to make the same point: geography and climate can mark a place for repeat disaster, and the people who rebuild there often do so without knowing the risk will return.
