Many strong earthquakes occur among destructive plate margins, this is because great stresses build up in the subduction zone as one plate is forced down below the other, this energy builds up to great force and is then released in an earthquake.

The most earthquakes occur in Alaska, followed by California.
Thousands occur every year, most of which are too small to notice.
Movement along the fault causes earthquakes; several thousand occur annually, although only a few are of moderate or higher magnitude.
I can't really say in detail .....but it is most likely that its because there is a default in that area ....like in California ..there are several defaults there and thousands of earthquakes occur each day there. BECAUSE its a active earthquake zone." :D Earthquakes also occur in Alaska and also; off the coast of Mexico....
Yes. Earthquakes occur most often along fault lines. There are also many different devices (seismograph) that sense seismic waves and can predict earthquakes.

Many strong earthquakes are caused by plates sliding apart.

Yes, many earthquakes occur under the ocean which is generally in water.
Lots and lots of earthquakes are happening every day, but many of these are too small, or hit in an unpopulated area, to be counted. However. there are about 70 strong registered earthquakes a year
alot of earthquakes
On average, there are roughly 20,000 - 30,000 recorded earthquakes every year.The USGS estimates that several million earthquakes occur in the world each year but many go undetected because they hit remote areas or have very small magnitudes.
Between 3000-4000
about 15 million
