Typical of Earthquakes

Huge effect of powerful earthquake hits, in the city or in the village are destruction of building and public infrastructure, thats why to reduce the risk we should know where is our position when an earthquake happens.

If on the beach there is possibility that a tsunami may occur and if on the hill or mountain there is possibility landslide may occur.

Earthquake could generate a tsunami if its occurs beneath the sea, not only batters coastal areas but can reach saveral kilometres inland.

Seismologist detected there are 3 types of earthquake.

• Volcanic earthquake despite by volcanic activity causing tectonic plates to move
• Tectonic earthquake despite by movements of tectonic plates, with a sudden elastic rebound of energy
• Induced earthquake despite by the release of energzy from other sources such as usage of explosives

The large segments of the earth' crusts are tectonic plates, violent displacement can happens of the eart's crust, during friction the boundaries of the plates exceeds a certain level.

Seismologist use the richter scale to measure the magnitude of an earthquake and to show the intensity they use the mercalli scale and the tools used to measure is called seismografh.

Earthquakes have claimed a lots of victims in the world.
