The magnitude of the puff pluck 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 hold the energy contained in the unstable waves.

The epicentre of an earthquake is the place flat above the focus. The shock waves or tremors from the Gujurat earthquake lasted about devil minut es, followed by aftershocks for more than a ! month.  | | Figure 1 - subroutine showing the Gujarat earthquake epicentre| The Impact| The scale of the jolt of the earthquake is about 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 detailed injured. Four districts of Gujurat lay in ruin and alto payher, 21...If you wish to get a full essay, order it on our website: BestEssayCheap.com
