Frequently Asked Questions
How are these disasters ranked? Rankings are based on confirmed or estimated direct death tolls drawn from peer-reviewed sources, including the [EM-DAT International Disaster Database (CRED, UCLouvain)](https://www.emdat.be) and [USGS Earthquake Hazards Program records](https://earthquake.usgs.gov).
Is the Black Death really a natural disaster? Historians and epidemiologists classify pandemic disease alongside geological and meteorological events when assessing large-scale natural catastrophes. The Black Death originated from *Yersinia pestis*, a zoonotic bacterium — firmly within the natural world.
Why is the Dust Bowl included? Although the Dust Bowl's direct death toll was lower than other entries, its displacement of 3.5 million people and multi-year agricultural collapse make it one of the most consequential environmental catastrophes in modern history.
