Hazards
According to the USGS (United Sates Geological Survey) Hazards are unpreventable natural events that, by their nature, may expose our Nation's population to the risk of death or injury and may damage or destroy private property, societal  infrastructure, and agricultural or other developed land. Hazards dealt with by the USGS include earthquakes, volcanoes, floods, landslides, coastal storms, wildfires, and  outbreaks of disease in wildlife populations.

Note: The concept of Hazards used by the USGS corresponds to what we will be referring to as Natural Disasters in this course.
