*Environmental Geology - a science which objectively studies geologic information and
applies it to contemporary environmental problems such as pollution, waste management,

System Any entity with a combination of interconnected components
Geologic Hazard Any geologic process or material that are harmful, hazardous, or costly to
humans.
Rapid Onset Geohazard Events or processes, such as Earthquakes and Flash Floods, that strike
quickly with little warning (e.g., Earthquakes, Flash Flooding, local
Tsunamis.
Anthropogenic/Human Hazard - Hazards that result from pollution and degradation of the
environment. Examples include acid rain, surface and ground-water
contamination, exposure to hazardous and radioactive wastes, ozone
depletion, and global warming.
Pollution - The unfavorable alteration of the environment by humans.
Recurrence Interval = Average Time between “Major” Events, such as Earthquakes or

Magnitude The destructive power of a Geologic Process or Hazard.
