Earthquake

Earthquake is one of the natural calamities. It is responsible for a lot of damage to living and non-living beings.

According to Aristotle, when the air compressed within the arch escapes, it shakes some part of the land. This emission is called volcanic activity. When the volcano bursts, the earth fails out. This causes pressure and imbalance and results in producing earthquake waves in the surrounding areas.

The second reason is isocratic adjustment. The surface of the earth has certain raised up blocks and certain depressed blocks. They keep the balance of the earth, when it moves revolving on units of axis. These raised up blocks are washed down due to various reasons and cause imbalance.

We could therefore see that earthquakes commonly occur in volcano prime areas and under the feet of hills and mountains. Earthquakes frequently occur in China, Japan, Philippines, southern parts of the Himalayas, Europe and western parts of North and South America.

All earthquakes do not cause severe damage. Those which are of severe intensity are really dangerous. There are scales to measure the intensity of the earthquake. The first one was Mescal's scale. The second one is Richter scale. It is measured with numbers. If the earthquake measures 7 points on Richter scale it causes severe damage. Those measuring 5 and less points may not cause much damage.

In conclusion, earthquakes have been intriguing us for some time now, but hope Earthquake is one of the natural calamities. It is responsible for a lot of damage to living and non-living beings.
