The different grades of the Risser sign give a measure of bone maturity and thus of the skeletal growth to be expected. In Europe, a scale ranging from Risser 0 to Risser 5 defines the grades from beginning ossification to complete fusion of the apophysis to the iliac bone. In the USA, 4 grades are defined.
The Richter scale is the ideal barometer for evaluating the overall seismic activity magnitude while the Mercalli scale is used for quake intensity. Other similar scales can be used to measure the intensity like the EMS scale, MSK scale, INQUA scale and Shindo scale.
