1. 1931 China Floods
The 1931 China floods were a series of floods that occurred in the Republic of China. The floods are generally considered among one of the deadliest natural disasters ever recorded. The total death toll ranges from 145,000 to between 3.7 million and 4 million. The reason for the huge difference in death is because Chinese sources say one thing and Western sources says another. Nine cyclones hit the region, whereas on average only two occur per year.

1556 Shaanxi Earthquake was the deadliest earthquake on record, killing approximately 830,000 people. It occurred on the morning of 23 January 1556 in Shaanxi.
An 840-kilometre-wide (520 mi) area was destroyed that morning, and in some counties as much as 60% of the population was killed. Most of the population in the area at the time lived in yaodongs, artificial caves in many of which collapsed with catastrophic loss of life.
3. 1887 Yellow River Flood
The 1887 Yellow River flood was a devastating flood on the Yellow River (Huang He) in China. The flood, that began in September 1887, killed some 900,000 people.
The 1887 and the 1931 floods happened at the same place, Yellow River. In both cases many people lost their lives and many were left homeless.
4. 1976 Tangshan Earthquake
The 1976 Tangshan Earthquake is believed to be the largest earthquake of the 20th century by death toll. The number of deaths on average is between 300 000 and 600 000.
The earthquake hit in the early morning and lasted 14 to 16 seconds. The earthquake had a magnitude of 7.8 on the Richter magnitude scale and it was followed by a major 7.1 magnitude aftershock some 16 hours later, increasing the death toll to over 255,000.
