| Abstract: | The methods of fuzzy information retrieval have been applied in this paper to analyse and study the scismicities in Urumqi since 1972, by means of four indexes including frequency variations, average magnitudes, magnitude variations and the largest earthquake in the upper period. The index that corresponded -with earthquake sensitivity and predictive principle have been discussed also. |
