肥东地震

with one comment

  大事件,肥东居然地震!好在3.4级属于弱震,一般不会带来人员伤害。当前国际常用的里氏级数(Richter magnitude scale)是用以十为底的对数形式(logarithmic scale)来计量的;具体说来,综合震波的最大波幅与震中距离后,对折算所得的数值取对数。因此,里特级从一级开始,每一级是前一级的10倍。从能量的角度来说,里氏规模每增加1级,能量约为前者的32倍;规模加2级,能量则100倍。下面是从1963至1998年全球地震震中位置分布(转载自Wikipedia):

  1. 肥东那个地震没多大,只是因为很少震,所以搞得大家很紧张。
