Why aftershocks are felt after an earth quake?

   For several hours, or even days, after a strongly felt earthquake, it is quite possible that people may feel more shocks. This possibility always exists, but keep in mind these four facts:
   • In most cases, these shocks (called aftershocks) will be smaller; therefore, the vibrations will be weaker.
   • Aftershocks do not mean that a stronger earthquake is coming.
   • Aftershocks are normal; they show that the earth's crust is readjusting after the main earthquake.
   • The number of felt aftershocks is quite variable and thus cannot be predicted. There might be several per day, or only several per week.
