Although the regions of greatest seismic activity are clearly defined and although there are scientific theories on what causes earthquakes, it is very rarely possible to forecast the time and place of a destructive earthquake. Moreover, even if such forecasting were possible, although it would reduce the number of lives lost it would not prevent property damage. Hopes raised by some predictions of an end to the era of unforeseen earthquake disasters have been shattered by other forecasts which proved far from accurate. The science of earthquake prediction is still in its infancy, and although scientists have made tremendous strides in their research, there is as yet no failsafe formula to foretell an impending earthquake with absolute accuracy.
