Earthquakes

IntroductionThe major contributor that is baffling in most of the geological formations on Earth is the denture margins. The plates have an approximate burdensomeness of 100 kilometers. This is non in truth thick when comp atomic number 18d to the radius of Earth, which is a radius of 6000 kilometers. The major plates are made up of Continental and oceanic crust. When these plates move they make water temblors. quake Movement more or less of the time we hap upon about seisms everyday in the news. Exactly what makes an earthquake? An earthquake is produced when in that respect is a sudden release of slide fastener, which causes a ruddy shaking in the crust of the Earth. This release of energy is ca employ when on that point is a build up of tension of two lithospheric plates. When these to lithospheric plates slue over against one another, attrition will cause the plates not to move. Because these plates do not move, the straining that is exerted on them causes a stir in shape of the plates. oer a period of time, the separate out that is being exerted on the plates increases to a point that causes the plates to move suddenly, producing the earthquake. The stress that was create up is released done the earthquake, only to build up again in time. Most of the time earthquakes are produced on gaolbreak lines.

A fault line exist where on that point is a crack in the crust of the Earth where there has been a movement of the plates (MSN Encarta, 2008). Earthquake MeasurementThe energy that is produced by an earthquake is hereditary through seismic waves. A seismograph is a machine that is used by scientist to assign and record the seismic waves. The seismograph is sufficient to detect both horizontal motions and vertical motions of the movements of the ground. The seismograph records these movements as a...
