Detailed explanation-1: -Magnitude and depth are two basic features of an earthquake that are important for understanding plate tectonics as well as earthquake hazard. Typically, the shallower the earthquake and larger the magnitude, the more potential for destruction.
Detailed explanation-2: -Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move relative to one another. Faults are caused by the bumping and sliding that plates do and are more common near the edges of the plates.
Detailed explanation-3: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
Detailed explanation-4: -More Earthquakes in the West The western United States lies along the boundaries of major tectonic plates that make up the Earth’s crust-the North American Plate and the ocean plates to the west. These plates are moving against each other, breaking up the crust along many faults like the San Andreas Fault.
