An earthquake scale

An earthquake scale can give you a general idea of how much damage an earthquake is capable of.

Earthquake Magnitude Scale
2.5 or less is usually not felt but can be recorded by a seismograph.
2.5 to 5.4 is often felt but only causes minor damage.
5.5 to 6.0 can cause slight damage to buildings
6.1 to 6.9 can cause a lot of damage in a very populated area.
7.0 to 7.9 is a major earthquake with serious damage.
8.0 or higher is a great earthquake that can destroy entire communities.

As you can see, anything under 5.0 will not cause that much damage.
