Crisis mapping (also known as disaster mapping) is the real-time gathering, display and analysis of data during a crisis, usually a natural disaster or social/political conflict (violence, elections, etc.). [1]
Hazard maps are created and used in conjunction with several natural disasters. [1] Different hazard maps have different uses. For instance, the hazard map created by the Rizal Geological Survey is used by Rizalian insurance agencies in order to properly adjust insurance for people living in hazardous areas. [2]

Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
Several tools can be used to assess risk and risk management of natural disasters and other climate events, including geospatial modeling, a key component of land change science. This modeling requires an understanding of geographic distributions of people as well as an ability to calculate the likelihood of a natural disaster occurring.

The resulting floodplain map is referred to as the 100-year floodplain. Estimates of the 100-year flood flowrate and other streamflow statistics for any stream in the United States are available. [3] In the UK, the Environment Agency publishes a comprehensive map of all areas at risk of a 1 in 100 year flood. [4]
