The Hazard Mapping method draws on what workers know from on the job experience. The Hazard Mapping approach works best when conducted with a small group of workers with some similarity in their work. For example, a group of workers from the same building or a group of maintenance workers who all worked in several buildings but do the same kind of

Example of a hazard map. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help prevent serious damage and deaths.
Learn how to create and use hazard maps to mitigate damage and prevent disasters caused by floods, volcanoes, earthquakes, tsunamis, storm surges, and geo-hazards. See illustrations of flood, volcanic, seismic, tsunami, and geo-hazard maps.
Example hazard map for Nowhere City. (Public domain.) Suppose the figure on the right is a hazard map for the area of Nowhere City developed for a 50-year time span and a 5% chance of exceedance. We would read the shaking hazards for Nowhere City as:
Seismic hazard is the hazard associated with potential earthquakes in a particular area, and a seismic hazard map shows the relative hazards in different areas. The maps are made by considering what we currently know about: Past faults and earthquakes The behavior of seismic waves as they travel through different parts of the U.S. crust The near-surface site conditions at specific locations of ...
