Earthquake will result in severe consequences such as large financial losses and companies bankrupt, people unemployed and even fatalities. Although earthquakes are not usual natural catastrophes, it is necessary to rationally analyze seismic risk on different kinds of fields like geology, earthquake monitoring and civil engineering. A recent title of combining these modern methods is Performance-based Earthquake Engineering (PBEE). It includes Probabilistic Seismic Hazard Analysis, fragility analysis of structure, casualty and financial loss estimation. In practice, probabilistic terms are used to identify specific details in most of problems related with seismology. Generally, the earthquakes people always talk about are those occur at the first moment and lead to worst influence.

After an earthquake of large magnitude (referred to as the main-shock), many induced events or aftershocks will occur. We will expect the inter-arrival times between aftershocks to be much shorter just after the main event. If the main-shock was near the structure of interest, so will be at least some of this family of aftershocks. Aftershock ground motions may cause weakening or collapse of structures perhaps already damaged (but not yet repaired) by the main-shock. In addition, aftershocks (implicitly or…
