What is Earthquake
Earthquakes are natural disasters that conclude to a widespread destruction and loss to the human life. An earthquakes effects differs on magnitude and power. Earthquakes occur frequently around the world, except in places that occur rarely. The demolition of the countries and cities is one example of the effects of an Earthquake
An Earthquake is the result of a unexpected discharge of energy in the earth crust due to precise reasons which creates seismic waves
The seismic movement of an zone refers to the frequency, type and size of the earthquake that has occurred over a period of time

For example: if you throw a stone ina pond of water, a vibration …show more content…

About 100,000 of these can be felt. Minor earthquakes occur nearly constantly around the world in places like California and Alaska in the U.S., as well as in El Salvador, Mexico, Guatemala, Chile, Peru, Indonesia, Iran, Pakistan, the Azores in Portugal, Turkey, New Zealand, Greece, Italy, India, Nepal and Japan, but earthquakes can occur almost anywhere, including Downstate New York, England, and Australia. Larger earthquakes occur less frequently, the relationship being exponential; for example, roughly ten times as many earthquakes larger than magnitude 4 occur in a particular time period than earthquakes larger than magnitude 5. In the (low seismicity) United Kingdom, for example, it has been calculated that the average recurrences are: an earthquake of 3.7–4.6 every year, an earthquake of 4.7–5.5 every 10 years, and an earthquake of 5.6 or larger every 100 years. This is an example of the Gutenberg–Richter …show more content…

Keep away from weak portion of the building and false ceiling. If you are outside: Avoid high buildings , walls , power lines and other objects that could fall and create block. Don’t run through streets. If possible , move on to an open area away from hazard including trees.

Major Earthquakes
One of the largest earthquakes that was recorder was 1556 Shaanxi earthquake, which arose on 23 January 1556 in the Shaanxi province found in China. 830,000 people died during the incident. Most houses in the sphere have been demolished, dwellings stamped out of loess hillsides and many victims were killed when these buildings collapsed. Tangshan earthquake in 1976, which killed approximately 655,000 people, was the most lethal in the 20th century.
The 1960 Chilean shaking is the largest recorded earthquake measured by a seismograph, succeeding the magnitude of 9 on scale. Its disturbance site was near Canete, Chile. The energy that was created by the earthquake was nearly as twice as the next most dominant earthquake, the Good Friday earthquake. Top 10 largest earthquakes were all mega thrust, however, of these the deadliest earthquake in the history of shaking was the Indian Ocean
