The following are signs that an earthquake may occur:

- changes in water levels in wells
- foreshocks
- changes in the magnetic properties of rocks

Aftershocks are not signs of an impending earthquake; rather, they are after events that occur following the main shock. Changes in air temperature are not typically considered a sign of an upcoming earthquake.
