两种空间插值方法在灯塔5.1级地震烈度分布中的对比研究

摘要

Using appropriate interpolation method in intensity rapid report is an effective means that compensates the insufficient of strong motion network density. In this paper, two interpolations, Inverse Distance Weighted Interpolation ( FIDW) and Kriging interpolation, were used in Dengta M5. 1 earthquake intensity distribution map. It is found that Kriging interpolation accords more with actual investigation.%采用合适的插值方法进行烈度速报，是有效弥补强震动台网密度不足的有效手段。本文应用两种空间插值方法距离反比加权插值法和克里格插值法，将辽宁灯塔5.1级地震强震动记录绘制了烈度分布图，结果发现：克里格插值法更符合实际调查情况。
