Earth quakes usually are caused by plate tectonics (where the continental plates or fragments thereof rub against one another), by volcanoes, and occasionally through human interference (such as recently in the Switzerland city of Basel).

Earthquakes are generally caused by tectonic plates moving against each other. The borders between them, called fault lines, are the centers of earthquake and volcanic activity. One place in the US well known for earthquakes is the area around the San Andreas fault line. This includes San Francisco and the Bay Area, which just had a minor earthquake about a month ago.

Earthquakes happen along tectonic plates boundaries.e.g Sam Andreas fault. The country with the highest rate of Earthquakes is Japan with a usual frequency of about one a day.

Earthquakes often occur in unstable parts of the earth,s crust. When due to tectonic forces a portion of the crust is dislodged or displaced.It causes tremors that travel in all directions from the centre of disturbance.

Over large faults in the earth. In U.S., on the west coast mostly and over a large fault in western Kentucky and Missouri. You will need to ask a geologist, possibly at a university, for exact locations.

this phenomenon occurs mostly in the subduction zone where two plates collides. this movement results to earquake or shake. the pacific ring of fire is an example of this location. fault lines are also places where you may feel quakes
