Earthquakes are commonly experienced in regions where the earth crust is in unstable portion. Tectonic occurances and volcanic activities are the main reasons for Earthquakes. Earthquake belts are generally young folded mountains like the Himalayas, Alps, Andes experience about 50% of Earthquakes.The continental slopes, mountains near the pacific ocean experience 40% of earthquake and the rest of the 10% are widely scattered on earth. So the two most important belts are the area surrounding pacific ocean and the belt via Indonesia, Himalayas to Mediterranean sea. (reference for percentages: L.D.Saini) Although the belts are expected regions of earthquake, there are unexpected regions which experience earthquakes also. Earthquakes cause a lot of damages but sometimes it brings notable changes such as areas rich in minerals coming closer to the surface, raise in sea floor to form dryland and so on.
