- When it came to measuring these big earthquakes, the Richter scale fell short.
- Nine on the Richter scale indicates an earthquake of absolutely awesome destructive power.
- This is one of the most destructive earthquakes of the twentieth century.

Major earthquakes are confined to particular active regions of the earth’s crust corresponding to the edges of the crustal plates, and most earthquakes are due to the release of strain energy associated with the relative motions of the plates. The intensity of earthquakes is expressed by the Richter scale, destructive earthquakes generally measuring between about 7 and 9
