Answer
No, it is not possible to predict an earthquake.
The Russians were the first ones to discover the P and S waves on the basis of which predictions were made. The theory of Plate Tectonics offers another means of prediction on scientific lines. Japanese use the methods of measuring the changes in sea level and variations in Earth's magnetic field to predict earthquakes.
However, no method is foolproof as has been proved by recent earthquakes in Japan, India and USA.
