An earthquake, one of the most destructive natural phenomena, consists of rapid vibrations of rock near the surface of the earth. It is the most terrifying of all natural phenomena and has brought fear since ancient times because of its sudden unpredictable occurrence and enormous capacity of destruction. A single shock usually last no more than a few seconds, although several quakes may last for as much as a couple of minutes. We have to know what earthquakes are in order for us to be prepared against them.
Earthquakes are tremors that move the earth. They can create a lot of damage. The main damage is caused to human, animal life and damage to properties. Earthquakes cause a lot of devastation, thereby causing great loss of life and property. Earthquakes are caused mostly by rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments. Earthquakes have happened around the world and may cause a lot of damage to homes. A 6. 3 earthquake destroyed historic buildings in Italy.
On January 12, 2010 a powerful 7. 0 earthquake struck Haiti and left a powerful impact on people. It caused people to die and made people want to help the people of Haiti. A final effect of an earthquake is producing various damaging effects to the areas they act upon. This includes damage to buildings and in worst cases the loss of human life. The effect of the rumbling produced by earthquakes usually leads to the destruction of structures such as buildings, bridges, and dams.
They can also trigger landslides. In conclusion earthquakes are not new to the world. It is a very common thing on many parts of the earth. Earthquakes are almost unpredictable and devastating acts of nature. There is still a lot more to be known about earthquakes that we still do not know about today. Prediction of large earthquakes is still under development, where prediction of small, unnoticeable earthquakes can be easy to predict because they happen mainly around fault lines.
