 Mark word for later review on this computer
Earthquakes below 6.0 on the Richter scale are unlikely to do serious damage where there are good building codes; though such earthquakes can result in a catastrophic loss of life when unreinforced masonry buildings collapse.

6.0 to 7.0 is a destructive earthquake that is likely to do significant damage

7.0 to 8.0 is a major earthquake that will do major damage. (There are about 10 of these each year.)

8.0 and above is a great earthquake.  (Typically there is only one of these each 5 to 10 years.)

The Richter scale is logarithmic with each point representing a 10-fold increase in the highest amplitude recorded on the seismogram and about a 32-fold increase in energy released.
