The most common natural disaster is a flood, which happens when an excess of water submerges ordinarily dry ground.
Floods are frequently brought on by prolonged periods of heavy rain, quick melting of the snow, or storm surges from tropical cyclones or tsunamis in coastal locations.
Particularly in low- and middle-income countries, there is a significant risk of flooding.
According to our calculations, 1.81 billion people, or 23% of the global population, are directly exposed to floods.

What is a flood?
170 million individuals who have been exposed to flooding live in extreme poverty (on less than $1.90 per day) and 780 million flood-exposed people on less than $5.50 per day.
In summary, 4 out of every 10 persons in danger of flooding do so internationally.
Why are there more floods breaking records around the World?
Wildfires are increasing, snow and rain patterns are changing, and precipitation is becoming more intense due to climate change.
Greater exposure to extreme flooding brought on by warming temperatures is damaging billions of dollars worth of property.
What is a flood?
Mudslides and debris flow during rainstorms are also made more likely as wildfires spread.
A catastrophic combination can result from the melting of snow and heavy rain.
In the mountains in and surrounding Yellowstone National Park, storms in mid-June 2022 delivered up to 5 inches of rain over three days, quickly melting the snowpack.
It turned into a flood when the rain and meltwater flowed into creeks and eventually rivers, damaging the roads, cabins, and utilities and requiring the evacuation of more than 10,000 people.
