Earthquakes Overview: Effects & Safety<\/figcaption><\/figure>\n<\/div>\n\n\n

Earthquake is the shaking of the earth’s surface.<\/strong> This happens due to seismic waves generated due to the sudden release of energy in the Earth’s lithosphere. Earthquakes<\/strong><\/a> can be very violent and have the potential to range from toppling and injuring people to destroying entire cities in a matter of seconds.<\/p>\n\n\n\n

Why do Earthquakes Occur?<\/strong><\/h2>\n\n\n\n

There are 7 plates inside the Earth<\/strong>, which keep rotating continuously. The area where these plates collide is called a fault line. The corners of the plates bend due to repeated collisions. When too much pressure builds up the plates begin to break. The energy below finds a way out and the disturbance is followed by an earthquake.<\/p>\n\n\n\n

Meaning of Earthquake Centre and Intensity<\/strong><\/h2>\n\n\n\n

The epicentre of an earthquake is the place just below which geological energy<\/strong> is released due to movement in the plates. Earthquakes vibrations are more intense at this place. As the frequency of vibration increases, its effect decreases. However, if an earthquake of magnitude 7<\/strong> or more on the Richter scale<\/strong> occurs, tremors are felt within a radius of 40 km. But it also depends on whether the seismic frequency is upward or downward. If the frequency of vibration is higher then less area will be affected.<\/p>\n\n\n\n

How is the intensity of an earthquake measured and what is the measuring scale?<\/strong><\/h3>\n\n\n\n

Earthquakes are measured with a Seismometer<\/strong>, which is called a seismometer. The earthquakes moment magnitude scale<\/strong> is measured conventionally, or the related and obsolete Richter magnitude is taken. An earthquake of magnitude 3 or less is often invisible, while an earthquake of magnitude 7 causes severe damage over large areas. Earthquake intensity is measured on the developed Mercalli scale<\/strong>.<\/p>\n\n\n\n

Earthquakes are measured on the Richter scale. It is called the Richter Magnitude Test Scale<\/strong>. Earthquakes are measured on a Richter scale of 1 to 9. An earthquake is measured from its center i.e. epicenter. The intensity of energy released from within the earth during an earthquake is measured. This intensity determines the intensity of the earthquake.<\/p>\n\n\n\n
