Mitigation: The avoidance of, lessening, or compensation for anticipated harmful effects of an action, especially with respect to the natural environment. Land-use planning: The preparation of an overall master plan for future development of an area; the plan may recommend zoning restrictions and infrastructure both practical and appropriate for the community and its natural environment; based on mapping and classification of existing human activities and environmental conditions, including natural hazards.

What might you do to protect yourself (both financially and physically) if you did decide to buy the house? Chapter 4: Tsunamis Distant tsunami: A series of gravity waves in the ocean originating from a source typically thousands of kilo-meters away from the shoreline that is inundated. These waves are produced by the displacement of the entire water column of the ocean by an underwater earthquake, landslide, volcanic eruption, or extra terrestrial impact. Tsunami run-up map: A two-dimensional representation of the level to which a tsunami has inundated or is projected to inundate a coastal zone. 2. How do natural processes cause a tsunami? What is the primary process? 5. Explain the relationship between plate tectonics and tsunamis. 8. What are the primary and secondary effects of tsunamis? 9. Describe the methods used to minimize the tsunami hazard. Critical Thinking 1. You are placed in charge of developing an education pro- gram with the objective of raising a community’s under- standing of tsunamis. What sort of program would you develop and what would it be based upon? Chapter 5: Volcanoes Cinder Cone: A conical volcanic hill formed by an accumulation of coarse pyroclastic material erupted from the volcano; also known as a scoria cone. Lateral blast: Type of volcanic eruption characterized by explosive activity that is more or less parallel to the surface of Earth. A lateral blast may take place when the side of a volcano
