What are the deadliest natural disasters in recorded history?

Natural disasters are sudden events caused by non-human forces such as earthquakes, floods, and cyclones that cause widespread destruction and loss of life. Historical records track massive death tolls from these extreme environmental events across the globe, including catastrophic tropical cyclones and domestic disasters.
