Abstract: A method of seismic wave spectrum analysis has been used to investigate the mechanics property of medium under seismic source environment along the Red River fault. The result indicates that there exists an environmental medium condition which is in favor of the creeping slip along the southern part of Red River fault.

Key words: Red River fault, Seismic spectrum, Medium environmet
