The Deadliest Natural Disasters, 1901-2026

The deadliest natural disasters of the last 125 years, built from the worst recorded disaster of each year since 1901. The 1931 China floods killed at least 422,499 people - some estimates run into the millions - and no natural disaster since has been deadlier. The 1970 Bhola cyclone, the 1920 Haiyuan earthquake, the 1976 Tangshan earthquake and the 2004 Indian Ocean tsunami follow. Where sources publish a range, this chart uses the lowest published figure throughout: the 2010 Haiti earthquake, for example, is reported as 100,000 to 316,000 deaths. Epidemics and famines are excluded, following the source's own convention.
