Explanation:
1. An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph. ... An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground.
2. An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel
3. When an earthquake occurs, seismic waves are created, which propagate away from the focus or hypocenter. The fastest waves, the P-wave, travels outward at a speed of about 3 to 5 miles/second. As the P-wave passes each seismic station, its arrival time is detected and noted by the real-time computers.
4. Completely turn off equipment like televisions and stereos when you're not using them.
Choose energy-efficient appliances and light bulbs.
Save water: some simple steps can go a long way in saving water like, like turning off the tap when you are brushing your teeth or shaving.

When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
