The effect of an earthquake can be measured with a [[seismometer]]. A seismometer detects the tremors of the earth and plots the tremors on a seismograph. The strength or magnitude of an earthquake can be measured using the Richter scale. The Richter scale was invented by Charles Francis Richter in 1935. The scale is numbered 0-10. A 2 on this scale is a tremor that is not easily recorded. And damage of size 5 (or more) in a wide area. The largest earthquake ever measured had a magnitude of 9.5.

No one can tell when an earthquake will happen. But we know where earthquakes are likely to occur in the future, such as near [[fault line]]s. An earthquake under the ocean can create a huge wave called a [[tsunami]]. Tsunamis can also cause a lot of destruction.
