So scientists tend to define this phenomenon as tangible shaking of the Earth surface, that is caused by sudden release of energy in the crust of the Earth. In other words, this release of energy results in seismic waves, which creates an earthquake itself. By the way, seismic waves are able to spread over great distances. However, only the epicenter of earthquake experiences the huge damage. The synonyms for the word “earthquake” are “quake”, “tremor”, “temblor”. Earthquake is a severe disaster. It is able to destroy people’s dwellings, cause significant casualties or even demolish the entire cities. I am sure that everybody has heard at least once in his/her life the term “seismic activity”. It is measured taking into account such factors as frequency, type and severity of earthquakes on the particular territory over a certain period of time. The force of earthquake is evaluated by Richter measure scale. Earth tremor is detected and registered by seismograph. The cases of earthquakes, their causes and results are studied by seismology.

The scientific view on the earthquake subject

Let’s speak for the beginning about the scientific classification of earthquakes There are several types of them:

  • Volcanic type (earthquakes caused by the huge strain in the bosom of volcano; the reason for this kind of earthquakes are lava and volcanic gas; earthquakes of this type are usually weak, but can endure for several weeks or months; as a rule, they are not dangerous for people);
  • Technogenic type (nowadays the opinion about human’s technological activity impact on the seismic activity is becoming more popular; scientists believe that the building of reservoir storages, extraction of natural oil and gas and some other people’s activities could lead to growing of seismic activity);
  • Landslide type (earthquakes caused by landslides; they are usually local and weak);
  • Artificial type (earthquakes caused by non-natural factors such as detonation of a great amount of explosives or a nuclear explosion under the surface of the Earth (tectonic weapon).

In addition, there three groups of earthquakes: strong, weak and micro-earthquakes.

Another catastrophic earthquake, known as the Great Chinese Earthquake, took place in 1556 in Shaanxi. It killed approximately 830 thousand people, which is thought to be the biggest number of killed people during the earthquake in the history. All buildings on this territory were destroyed and a half of local inhabitants died.

The most severe earthquake in the history of the United States happened in Alaska in 1964. Its magnitude was 9,1-9,2.

In your Haiti earthquake essay you should mention that it happened in 200 and had magnitude of 7. The property damage is estimated in 5,6 billion euro. 222 thousand people were killed and 311 thousand people were injured. The last earthquake of such magnitude took place on Haiti in 1751.

One of the most known contemporary cases of earthquake was one on the eastern coast of Japan. It has magnitude 9,0-9,1. It happened in 2011 near the eastern coast of Honshu island. Scientists claim that it was the most powerful earthquake in the known history of Japan. Moreover, this earthquake caused the massive tsunami, which resulted in the great damage for the northern part of Japan. The official amount of casualties as result of the tsunami and the earthquake is 15 thousand people. Besides, this earthquake caused the accident on the Fukushima nuclear power station.
