How to act in an Earthquake

At-risk areas, it is important to be prepared both to give an immediate response to medium term, as well as learn to act after the occurrence.

Noting the tremor ...
► The reaction must be fast, without losing the Cayman.
► In case you are inside a building, do not leave abroad. We need to seek protection under strong structures (bed, lintel of the door).
► The head must be protected. We must move away from windows, shelving and falling objects.
► On the outside, do not approach or enter a building and is due to be away from electrical wires, cornices, windows ... We must always look for open spaces.
► If you are driving, it is best to stop at a place away from bridges and fissures in the ground.

... and then the earthquake
► should be cut off gas, water and electricity to prevent leaks and subsequent fires.
► North shoe should be thick soles to protect them from sharp objects, and we must monitor with the furniture in an unstable.
► There may be aftershocks affecting the buildings damaged. It is better to be on the outside.
► Water for consumption should be bottled, as the supply may be contaminated.
► The phone should be used only in urgent cases.
► In coastal areas, the tremor may follow a tsunami. It is advisable to inform the radio.

Earthquakes - Why and how it vibrates the earth?

They are the most sudden and devastating. Are caused by the movement of tectonic plates ground, and are measured by their magnitude (Richter scale) and intensity (MSK).

• The hypocenter or focus is the internal point where the earthquake originated, and the epicenter is its projection on the surface. If it is at sea can result in tsunamis (large waves that propagate towards the coast).

• The seismic waves are amplified in soft ground and very thick (plains, lakes ...). In addition to the vibrations of the ground, landslides could occur on land and liquefaction,

• The scale of magnitude (Richter) is logarithmic: supposed to be an earthquake measuring 5 is 10 times more destructive to a grade 4. According to this, an earthquake of 2.5 is in the vicinity, one of magnitude 6 is potentially destructive, and more than 7 is a major earthquake.

• The energy that releases an earthquake of magnitude 8 is the 1025 ergios, equal to 10,000 Hiroshima bombs like. An earthquake and takes place every 8-10 years, and is detected within a radius of 1,000 km away.

• The scale of intensity (MSK) takes into account the destructive effects of the quake according to the loralización; a strong earthquake in a desert area that would lower a weaker but close to a city.

• In 1943, there were a total of 41 earthquakes of magnitude 7 or higher (record of the century). The year 1986 has been, for its part, the least active of the century, with only six of this magnitude.

How does an Earthquake Take place?

The surface of the tiera is divided in boards that fit as a puzzle. These boards are in movement and they advance an on the other one destroying their edges.

The continents are embedded on the boards and in turn, they move together with them in a named movement it "derives continental."

This movement, produces a pressure on the layers of rock of the terrestrial surface that it accumulates with the years until these cannot support it more.

It is this way then that begin to move and to crack destroying everything that that is on them. It is then to those "shakeouts" that you them flat Earthquake or Earthquake.

The place where it takes place the earthquake inside the earth, "focus" is named; and the biggest intensity feels in the epicenter; that is the point of the surface that is exactly above the focus.

The intensity of this, of it measures with the scale "Mercalli" that 1 go from the soft tremor of the point, to the total destruction of the point 12.

The seismic fields are distributed throughout the tectonic boards.

As fact not pettier, most of the earthquakes take place on-board of the Sea Pacific.
