In order to be classified as a disaster, it will have profound environmental effect and / or human loss and frequently incurs financial loss . </P> <P> Notes: The list does not include several volcanic eruptions with uncertain death tolls resulting from collateral effects (crop failures, etc .), though these may have numbered in the millions; see List of volcanic eruptions by death toll . The list does not include the man - made 1938 Yellow River flood, caused entirely by a deliberate man - made act (an act of war, destroying dikes).
