Tóm tắt

Measurement theory is applied to the seismic intensity scales for the purpose of classifying them. Some basic tenets of scale classification are discussed, along with properties of scales of different ranks. The seismic scale is tested for uniformity. It is shown that the Mercalli-type seismic intensity scales at present in use have the rank of an interval scale, thus proving that arithmetic operations can be applied to macroseismic estimates expressed in the standard intensity grades.
