According to seismologists, an earthquake that registers 2 on
the Richter scale is hardly perceptible, while and earthquake that
measures 5 on this scale is capable of shattering windows and
dishes and is generally classified as "minor". The San Francisco
earthquake in 1989 caused great damage and registered 7.1 on the
Richter scale.
Richter scale: M=2/3logE-2.9 M is magnitude and E is energy in
Joules
