What is the most dangerous natural disaster?
In terms of total lives and goods lost, floods are the most serious natural disaster.
The worst dangerous natural disaster, the Central China Floods, occurred in summer 1931. The Yangtze River overflowed and caused a series of floods in China nearly 85 years ago. As a result of this flooding, an estimated 3.7 million people died from drowning, disease and starvation, some due to aftermath events.
