Abstract
Background and Objectives: Examining experiences related to past earthquakes, especially in developing countries suggest that in addition to fatalities and injuries caused by the main earthquake the large aftershocks also have effect to increasing the mentioned consequences. In this Research has presented a practical method in predicting the large aftershocks with the aim of reducing fatalities and injuries caused by their occurrence.
Materials and Methods: The survey method used in this study is based on statistical analysis related to basic parameters of the primary aftershocks such as: time occurrence, magnitude with aim of prediction of time the large aftershock for alarm and evacuation to people from non-resistant buildings. In this research has used seismic quiescence theory (time distance between aftershocks event) and analysis of the normalized data of depth and magnitude of primary aftershocks for the prediction of time and vulnerability level caused of the large aftershocks in Sefidsang earthquake in northeast of Iran.
Result: Data analysis suggests that there is the definite relationship between magnitude and seismic quiescence of primary aftershocks that this relationship can be base of analysis for prediction of the time of the large aftershocks.
Conclusion: The results of this study indicate that predicting the time and the rate of vulnerability of the large aftershocks can be obtained by combining the outputs of the two aforementioned analyzes.
