    The Yellow River overcame dikes in late September 1887, causing a massive flood that killed at least 930,000 people.

Background and detail

Background. Farmers near the Yellow River had built dikes for centuries to manage the river, which rose due to silt deposition. In 1887, heavy rain swelled the river, causing it to overcome these dikes. The water broke through near Huayuankou, close to Zhengzhou in Henan province, initiating a massive flood that spread quickly through low-lying plains.

Impact. The flood covered an estimated 50,000 square miles, swamping agricultural settlements and commercial centers. It killed at least 930,000 people, making it the single deadliest flood in Chinese history. Estimates vary widely, with some sources citing a range between 900,000 and 2 million deaths. It is also ranked as one of the largest natural disasters by death toll in recorded history.
