摘要
Gutenberg-Richter (G-R) scaling relations are commonly used on seism prediction. The variance of b-values can reflect the seism active degree of the area. B value in frequent failure time is lower than in stable failure time. We use the curve to calculate the values of parameters a and b in the Gutenberg-Richter (G-R) relation, draw a graph of the b-value and the ratio of the number of failures over time, and find that the trend is reversed, which prove that the b-value can reflect the ratio of the number of failures. Draw the trend curve of a-value and lgN. By comparing and finding the same trend, it is proved that the a-value can reflect the overall level of failure data. The relationship between a and b-value is analyzed and the influencing factors on activity parameters are discussed. (C) 2021 Jordan Journal of Mechanical and Industrial Engineering.
