Most earthquakes occur near faults because the interaction of tectonic plates (moving against or away from each other) causes a buildup of stress, which is eventually released in the form of an earthquake.
Earthquakes don't necessarily occur along faults though. Volcanic activity and isostatic imbalance (local imbalance from rapid geologic change - for example, ice melting) are two other causes of earthquakes.

Which are used for short range predictions of when earthquakes will occur?
Answer: Strain in rocks near faults.
How is it known that earthquakes are the result of movement along faults?
Because after earthquakes, it is possible to see examples of displacement of the ground across faults.
What types of plates do Earthquakes form on?
Earthquakes typically occur on a any fault because the most common earthquake is the tectonic earthquake and it occurs on all the faults, though usually has the most effect on strike-slip faults (like the San Andreas fault).
What are the 3 different types of rock movement in earthquakes?
Normal faults, reverse faults, and last but not least transform faults.
What did grove Gilbert discover about earthquakes?
He saw that faults were a major cause cause of earthquakes
What is the relationship between the locations of volcanoes and earthquakes with regard to faults?
Earthquakes and volcanoes are most common near the faults at plate boundaries.
Do earthquakes occur mostly near faults lines?
yes they always do, if you go onto the website wikipedia it can tell you all about it!
Do earthquakes mostly occur at faults that are away from plate boundaries?
False. Earthquakes mostly occur along faults that are at or very near to plate boundaries.
Which is used to determine earthquakes risk?
Strains in rocks near faults
Do earthquakes often occur at at faults that are away from plate boundaries?
Yes, but not as often as earthquakes happen near plate boundaries
Which are used for short range predictions of when earthquakes will occur?
Answer: Strain in rocks near faults.
Which kind of boundary is seen in earthquakes that are normal faults?
Transform boundaries are seen in earthquakes that are caused by normal faults. Some types of faults are listric or ring faults.
What factors have proven to be consistent predictors of major earthquakes?
some changes in the tilt of the land near major faults
How faults produce earthquakes?
Faults DO NOT produce earthquakes, faults are produced by earthquakes. This means that earthquake loci are centered on and along faults. The energy released by an earthquake is the stress energy built up as a result of plate tectonic forces.
What are earthquakes associated with?
Faults
What are faults caused by?
earthquakes
Why do scientists think that an earthquake will occur at the San Andrea's fault?
Because it is a fault and earthquakes usually occur near faults.
