"Earth quakes"

Earth is the most fundamental ingredient of the universe. From the time of creation of the universe these earthquakes are the part of our universe and especially for our earth.These earthquakes causes huge destructions. From the modern technologies now we can study that what are the causes of these earthquakes.

In the beginning of the universe our earth was nothing but hot molten mixtures of different metals. But with the passage of time, this hot mixture cold down and our universe was created. As more time spend this hot molten metals (or lava) further reduced to temperature and formed solid crust which makes the lands, valleys, mountain etc, but the interior of the earth is still like hot molten metal as it existed in the conditions billions of years ago. These hot molten metals always tries to come out from the earth for which it always found the weaker part of the earth crust. Molten metals found in the particular area applies pressure in that part of the crust. In this action and reaction, lot of force is involved which results the earth to shake, and hence it causes earthquakes.

The second reason for the earthquakes is due to Plate Tectonics. The earth's crust consists of a number of sections or plates that float on the molten rock of the mantle. These plates move by currents caused by heat rising from the molten crust. When these plates are also

Effects or disasters by earthquakes are very astonishing. Earthquakes kills hundreds of peoples, topple down the houses of hundreds of people and sometimes on larger scale, it can completely finish the entire city. The most destructive earthquake was observed in the Nealum valley at Muzaffarabad, Pakistan. It was occurred on October 8, 2005. The magnitude scale read about 7.6, which can be considered as most horrible earthquake ever occured in any part of Pakistan.

About 4 million people became homeless. It was thought that as many as 73,000 people might have died and another 1,400 in Kashmir. The whole mountainside sheared off during the earthquake. Most of the school building came down on the little children which were in their classrooms at that time of the day. Two major hospitals were badly damaged. Kwala was a remote village where all the houses had been destroyed. In Chela Bandi, Muzzaffarabad, a girl’s school was in ruins. Around 150 girls were killed in that building.
