This collection of video clips describes the worst earthquake, tsunami, volcanic eruption, avalanche and lake overturn in recorded history as measured by estimated death tolls.
The disasters featured here include an earthquake that killed nearly one million people and a volcano that lowered temperatures around the globe and caused "the year without a summer".
No matter what their scale, all natural disasters are tragic. We recognise that comparing the severity of different events across long periods of time is somewhat subjective.
