Natural hazards include: earthquakes, volcanic eruptions, and many more do not become disasters until they affect people however depending on the location and other variables that may be in harms way is called a hazard exposure. Risk determines if the factor has high value or low value. Mitigation is activities to reduce losses from future disasters, including prevention and protection. Projects can be undertaken to prevent future disasters to reduce the need for larger response capability. However, the price of inaction outweighs the cost of corrective action. Ways of mitigation: 1. altering hazard 2. averting hazard 3. adapting to the hazard.
