An earthquake also known as a quake , tremor or temblor is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth 's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The seismicity , or seismic activity , of an area is the frequency, type, and size of earthquakes experienced over a period of time. The word tremor is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami.

SUMMARY The chapter presents planners with 1 a description of the most hazardous geologic phenomena-earthquakes, volcanoes, and tsunamis-and their effects; 2 a discussion of how to use existing information to assess the hazards associated with these phenomena and incorporate mitigation measures early In an Integrated development study; 3 sources of geologic data and maps; and 4 information with which to make key decisions early in the planning process. The processes that have formed the earth continually act on or beneath its surface. The movement of plates in the earth's crust and local concentrations of heat are a continuing source of hazards to people and their structures.
