China’s second-longest river, the Huang He (Yellow), is the source of the three deadliest floods in history. Flooding in 1887, 1931, and 1938 killed millions of people and caused an incalculable amount of damage.
The 1931 flood was the most destructive. An area equivalent to the size of England was deluged by flood waters that carried debris, diseases, and destroyed crops.
Severe destruction and chaos prevented officials from determining an exact death toll, but it’s estimated that 850,000 to 4,000,000 people were killed by the flooding and its lingering effects. Approximately 80 million people were left homeless.
