Earthquakes are typically prompted when rock underground suddenly breaks alongside a fault. This sudden launch of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing in opposition to each other, they stick a little. They don't simply slide smoothly; the rocks seize on each other. The rocks are nevertheless pushing towards each other, however now not moving. After a while, the rocks spoil because of all the stress that is built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they proceed to go till they get caught again. The spot underground the place the rock breaks is known as the focal point of the earthquake. The area proper above the center of attention (on pinnacle of the ground) is called the epicenter of the earthquake.
