How to classify, measure and differentiate earthquakes

The Earth’s crust is made up of large parts, plates, which float on the fiery and current substance – magma. When these boards, because of its very slow moving touch, they deliver the stimulus that causes earthquakes. Earthquakes can cause disturbances caused by magmatic activity. Hypocenter is the point within the earth, who had a disorder that causes seismic waves. Place on the surface directly above the hypocenter is called the epicenter.

Seismic waves are vibrations caused by disturbances in the Earth’s interior, which is from the hypocenter or focus transferred to its surface if their oscillation parallel to the direction of expansion, we are talking about a longitudinal wave, and if the oscillation perpendicular to the direction of propagation, in which case we have a transversal waves .

When the rocks around the collision elastic enough, they mitigate the attack and thus prevent the formation of an earthquake. However, if they are particularly rigid, blow make them broken and form an earthquake.

Diagrams which register the seismograph, have a scale of values according to the severity of the accident. Eg. attack of 2 degrees MCS (Mercalli- Cancani- Sieberg) scale is very weak, and a 12-degree disastrous, with devastating consequences. It is also known Richter scale degrees from 1 to 10.

Today it is possible to predict just a place of an earthquake, but not the time and severity of the accident. We know from experience that animals are more sensitive than humans and are becoming restless a few minutes before each earthquake. Man has learned, within its capabilities, to protect themselves from these natural phenomena. In earthquake prone areas, such as. in Japan, built houses of wood and paper or, more recently, modern technology, of reinforced concrete, which possesses the necessary elasticity.
