They take place between the crust and mantle. They are shallow because the tectonic plates move, and when they move past each other it is like rubbing your hands against one another with something sticky on them, eventually one just snaps and that is what creates the shallow quakes.
One that occurs close to the earth's surface. Shallow earthquakes are more damaging than deeper earthquakes to due there being less rock to absorb the shaking.
Earthquakes that happen in shallow water cause tsunami and other side affects like landslides.

We can't predict when an earthquake will happen, however: Earthquakes happen when tectonic plates 'slip'.
Divergent plate boundaries.
mid-ocean ridges
Shallow focus earthquakes generally cause more damage.

Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
