用地震断层陡坎的形态方程确定古地震事件的年代

USING THE SHAPE EQUATION OF SEISMIC FAULT STEP TO DETERMINE THE CHORN OF AN EARTHQUAKE EVENT

通过对地震断层陡坎演变过程的分析，应用均匀物质扩散理论建立地震断层陡坎的形态方程，推断古地震断层陡坎的年龄，从而确定古地震事件的期次及年代。用该方法对二台活断层古地震断层陡坎进行计算，所得结果与用其它方法确定的古地震事件的期次及年代对应较好。

Based on the analysis of evolutionary process of seismic fault step,the shape equation ofseismic fault step was built by applying uniform matter diffusion theory- Using the equationcan obtain the age of a paleoearthquake fault step,thus determining the chorn and perlod-time of the paleoearthquake. The paleoearthquake step on Ertai active fault was taken as anexample in this paper;its chorn and period-time were drawn from the shape equation.whichis corresponding to the results from other methods very well.
