The Three Types of Threats and Hazards

FEMA organizes threats and hazards into three groups, so they can be better understood and addressed. They are:

  • Natural hazards, which result from acts of nature
  • Human-caused incidents, which result from the intentional actions of an adversary
  • Technological hazards, which result from accidents or the failures of systems and structures
