It is also known as tremblor, tremor or quake. Let us tell you that just below the earth's surface where earthquakes start is called hypocenter and just directly above the surface of the earth is called epicentre? Size of an earthquake may differ and sometimes it is said that weak earthquakes are not felt also but the violent one may cause destruction and may destroy whole cities. It all depends upon the frequency, type and size of the earthquake experienced over a period of time. The vibrations caused by an earthquake are detected by a seismometer and on a seismograph, it plots these vibrations. Richter scale also measured the strength or magnitude of an earthquake. When an earthquake measured around 7 or 8 on the Richter scale, it can be devastating.

Causes and Effects of Extinction

Tsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. The most common cause is earthquakes. See the percentages on the right for the geological events that cause tsunamis. A disturbance that displaces a large water mass from its equilibrium position can cause a tsunami. In order to understand the role of violent seafloor movement as a major cause of tsunamis, one needs to understand plate tectonics.

A tsunami is caused by an earthquake, landslide, or volcanic eruption on the sea floor. During an earthquake, seismic waves can produce powerful ocean waves.


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.

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.
