It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. .

Explain how . seismograph data is used.. The Seismograph. Seismic waves cause the seismographs drum to vibrate but the suspended weight with the pen attached moves very little. Therefore the pen remains still and records the vibrations on the drum.. Essential . Questions. What are earthquake magnitude and intensity and how are they measured?.
