- Abstract:
- The time and space scanning calculation of the goodness of earthquake fit was done in the epicenter of 2016 Menyuan MS6.4 earthquake and its adjacent area by the principle of G-R formula. The time scanning results show that the goodness of earthquake fit values were decreased significantly and continued to keep the lower value in the epicenter and its adjacent area in 27 months before the earthquake,then the value has been significant decreased again within two months before the earthquake. The space scanning results show that the distribution of goodness of earthquake fit contours have significant changes in the epicenter and its adjacent area before the earthquake and two adjacent low-value zone have expansion and consolidation,the goodness of fit value decreased significantly in epicenter region and the entire study area. All of these results show that the accumulation of the stress in the seismogenic process leads to the imbalanced proportion of the small and large earthquakes before the earthquake,so that the goodness of fit values appear low values in the epicenter and its adjacent area.
