Earthquake, due to faults in the earth's crust suddenly spread in waves, the vibrations pass through the media and to shake the earth 'event.

Earthquake, people still safely adopted, and all structures located on the foot presses the ground and damaged the play, showing the loss of life will undergo a natural phenomenon yıkılabileceklerini way.

How an earthquake occurs, seismic waves, the way in yerduvarı yaıldıklarını, measuring instruments and methods of evaluating, and recording branch of science that studies other issues related to the earthquake, "Seismology" is called.

Types of earthquakes: 
Earthquakes may have different types depending on their causes. A large part of Earthquakes happen as described above, albeit with small amounts of other types of earthquakes bulunmaktadır.Yerkabuğunu natural causes earthquakes are usually caused by movement of layers forming the "tectonic" earthquakes are treated as earthquakes often occur in these plates. This category includes 90% of earthquakes. Tectonic earthquakes in Turkey, a large majority of the earthquakes. The second type of earthquake, "volcanic" earthquakes. These are caused by volcanic eruptions. Melting depths of the earth, the earth out of matter as a result of physical and chemical reactions during the outbursts of gases are made ​​known to occur with this type of earthquakes. These volcanoes are related to local. Some of the earthquakes in Japan and Italy fall into this category. No active volcanoes, is not this type of earthquake in Turkey.
Another type of earthquake the "Collapse" earthquakes. These underground cavities (caves), coal mine galleries, salt and gypsum soil blocks collapsing ceilings consist of cavities caused by melting. Felt and low energy, causing much harm a local effect. Large landslides and causing meteors are also known to be small sarsyntylara.

After the earthquakes in the deep sea at the bottom of the sea, to the shores of the sea waves, and sometimes causing major damage occurs along the coast that their "Tsunami" (Japanese for big harbor wave) is called. In Japan, where underwater earthquakes tsunami in 1896 killed 30,000 people.

Measuring Earthquakes: 
Seismologists can not observe with the naked eye, and direct measurements based on a variety of numerical data and analyze earthquakes. So basically two different but equally important, they analyze earthquakes measuring system: the size and violence. The energy of an earthquake, system size, density at any point of the vibration system is measured intensity.

Earthquake Magnitude and Frequency: 
Have minor earthquakes per day in many parts of the world, even in the United States, Alaska and California, Indonesia, and Japan more than a day out in the number of quakes is ok. Major earthquakes are less frequent. England yapylan calculations revealed the following result:

3.7 or larger earthquake every year
4.7 or larger earthquake every 10 years
a 5.6 or larger earthquake once every hundred years
90% of the world's earthquakes and large earthquakes occur in about 80% of Pacific Region.

Earthquakes effects:
-Windows broken
-Buildings collapsing
-Fires may
Tsunamis can be seen in-
-Landslides occur
-Epidemic may hastatıklar
-Basic may experience difficulties in obtaining the necessities of food and

large earthquakes in history:
-Istanbul - Minor Apocalypse, 1509 Big Istanbul Earthquake
-Lisbon Earthquake (1755)
-Istanbul - Istanbul 1766 Great Earthquake
-San Francisco Earthquake (1906) - Size of 7.7-8.3. Earthquake and
resultant fire caused major damage.
-Erzincan Earthquake (1938): 8.7 earthquake approximately 40,000 people
-Great Mexico Earthquake (1985). 8.1 earthquake.
-Armenia Earthquake (1988)
-Erzincan earthquake (13 March 1992) 3500 6.9 earthquake nearly
people died.
-Izmit Earthquake (17 August 1999) 7.4 earthquake to 50,000
people died.
-Duzce Earthquake (12 November 1999): 7.2 earthquake approximately
2000 people lost their lives.
-Chi-Chi Earthquake (1999)
Earthquake-Baku (2000)
-Gucerat Earthquake (2001)
-Dudley Earthquake (2002)
-The Indian Ocean Earthquake (2004) recorded the most severe
size of 9.1-9.3 with earthquakes, tsunamis biri.Yarattığı 229 000 'led to the deaths of over.
-Sumatra Earthquake (2005)
-Keğmir Earthquake (2005), approximately 80,000 people killed.
-Java Earthquake (2006) magnitude of 9.7. Approximately 700,000 people

Natural Disasters and Prevention Ways :
Earthquakes, erosion, flood, landslide, avalanche What is it?

The world is seen as short-term shocks of earthquake the earth's crust is called a variety of reasons. Heard the place is called the most violent earthquake epicenter. To be effective in places where space is called an earthquake tremor. Precautions Against Earthquake can not prevent earthquakes, but can take measures to minimize earthquake damage.

Areas of loose soil away from buildings, should be a hard place. Must be single-or two-storey houses. Large buildings of reinforced concrete or steel, should be robust.

Instant Earthquake What to do:
Take the shape of the fetus during the earthquake shaking yanynda end where we expect solid objects. Out immediately to get out of an abandoned place where the end-shake.

Quality material used for making buildings earthquake resistant. Should not exceed two floors of the buildings. Structures inspected and illegal constructions should not be allowed during construction.


Settlements in the fall of the water flooding or flooding is a natural disaster. Flood water flows rapidly and leads from the front of everything, causing loss of life and property.

Flood prevention works:
Settlements out of flood zones should be removed. River beds cleaned and expanded. Rivers should be controlled by dams and weirs. Ağaçlandırılmalıdır bare areas. Cascading bed of the rivers with the flow rate should be relieving orthogonality.


To move into the top layer of soil have eroded due to water or wind is called erosion. Süpürmesidir wind up with another form of erosion.

Landslide (LANDSLIDE)

The displacement of rock fragments and soil slumping or sliding layer is called a landslide. Eastern Black Sea region of our country are the most landslide.

 Studies in the Prevention of soil erosion:
Covered with vegetation of the steep and barren places. Work done away from the landslide areas of the roads. Oyulmamalıdır dug up portions of skirt over the steep places. If necessary, a retaining wall should be performed. Flowing water-resistant wall beds should be controlled. Opened more steep and deep cuts in road construction. Locations outside the settlement land slip areas removed.


Moving sliding down the mountain in winter, is called an avalanche progresses kaymasyna progressive abdominal mass and strength. Most avalanches occur in Eastern Anatolia region.

Measures against this disasters :
Places where the slope very ağaçlandırılmalıdır enough. Screens must be used where there is a strong possibility of avalanches. Should be done away from areas where avalanche of winter sports.
