地震新闻报道中中国地震死亡人数时间序列特征研究

选取了1996-2017年国内18次震例,统计新浪网对地震死亡人数的报道数据,利用对数函数对震例进行了数据拟合,结果表明:(1)地震死亡人数与其被报出的时间所呈现的曲线有着很好的相关性,死亡人数越多,确定最终死亡人数的时间也就越长。(2)地震死亡人数接近总数的报出时间越短,表明救援能力越强。从18次震例中体现出我国的地震灾害的救援能力以及地震灾害响应情况在各个震级档中较为一致。

Time Series Characteristics of Earthquake Deaths in China News Reports

Selecting 18 earthquake cases in China from 1996 to 2017, we use statistical data of earthquake deaths reported by Sina net to fit the earthquake deaths with logarithmic function. The results show that:(1) There is a good correlation between the number of earthquake deaths and the curve of the reported time; the more the number of deaths, the final death is determined. The longer the number of people.(2) The shorter the time of the earthquake death toll approaching the total, the stronger the rescue capability. The rescue ability of earthquake disasters and the response of earthquake disasters in China are consistent in all magnitudes from 18 earthquake cases.
