The Effect of Two Fault Segments Sliding Velocity on Strong Earthquakes

Article Preview

For researching the strong earthquake recurrence period of Kusai Lake and Xidatan fault segment in different sliding velocities, we apply the spring-block model (or BK model) controlled by the velocity and state depended frictional constitutive. Through numerically solving the one order differential equations picturing the block (or fault segment) motion, the parameter charactering the fault segment motion is achieved. Finally, we find the recurrence period of strong earthquake is shorter in fast sliding velocity than that in slow one. The 0.1 mm changing of fault segment sliding velocity per year will make the several hundreds years of variation in strong earthquake recurrence period.
