The deadliest flood in history, based on available records, was the 1935 Yangtze flood in China.
The Deadliest Flood on Record
The 1935 Yangtze flood is documented as one of the most catastrophic natural disasters, directly causing an estimated 145,000 fatalities. This monumental flood event struck extensively across the densely populated regions along China's Yangtze River. Its profound human cost serves as a somber reminder of the destructive power of major river systems when they overflow and the critical importance of robust flood management strategies, early warning systems, and comprehensive disaster preparedness in areas prone to such extreme natural phenomena.
Other Historically Significant Floods
Throughout history, countless floods have resulted in immense loss of life and widespread devastation. While the 1935 Yangtze flood is recognized for its confirmed high death toll, other historical events, including significant storm surges, have also contributed to catastrophic fatalities. The exact numbers for some of these older events can often vary due to differing historical accounts, estimation methods, and challenges in accurate record-keeping over centuries.
