An seism is a sudden vibration or shakiness in the Earth. More than 150,000 tremors strong enough to be matte up by humans occur each year intercontinental (see Chance of an Earthquake). Earthquake motion is caused by the quick play out of stored potential energy into the kinetic energy of motion. Most earthquakes argon produced along faults, tectonic plate boundary zones, or along the mid-oceanic ridges (Figures 1 and 2). At these areas, large masses of fluctuate that are moving past each other can obtain locked due to friction. The magnitude of the shock wave released into the surrounding rocks is controlled by the quantity of stress built up because of friction, the distance the rock moved when the slippage occurred, and ability of the rock to transmit the energy contained in the unstable waves.

On 26 January 2001 an earthquake registering 7.9 on the Richter scale leaf devastated the Indian state of Gujurat. It was the second largest recorded earthquake in India, the largest being in 1737, and was the worst natural disaster in India in more than 50 years.
The earthquake struck at approximately 8.



46am local time, its epicentre located 80 kilometres northeastern United States of the city of Bhuj (see Figure 1). The place in the earths crust where an earthquake occurs is known as the focus. The epicentre of an earthquake is the place flat above the focus. The shock waves or tremors from the Gujurat earthquake lasted about devil minutes, followed by aftershocks for more than a month.

The Impact|
The scale of the jolt of the earthquake is almost impossible to comprehend. The shock or seismic waves spread out in a 700 kilometre circle from the epicentre, and within this area the devastation was immense. There were more than 20,000 deaths and 167,000 quite a little injured. Four districts of Gujurat lay in ruin and alto payher, 21...If you want to get a full essay, order it on our website: Orderessay
