The research on attenuation features of intensity in the yunnan region by using intensity isoseismals of 127 earthquakes , and the following three conclusions have been put forward : ( 1 ) average ratio values of long - axis to short - axis of innermost isoseismal in the yunnan region is larger than eastern china and smaller than western china 摘要本文利用127次地震等震線資料,對云南地區地震烈度衰減特徵進行了研究,其結果表明: ( 1 )云南地區地震烈度極震區等震線的長軸、短軸之比的均值,高于我國東部地區而略低于西部地區的平均值,烈度衰減方向性強。

In this paper isoseismal map of this earthquake was drawn for these areas by sorting out and analyzing data systematically collected , furthermore , the characteristics of the earthquake damage were discussed 本文系統收集了該震有關資料,并通過整理分析勾畫出其烈度分布,以探討該震的震害特點。
