摘要
湖南省境内现今仪器记录地震约有1/5的地震有感,M_L≥2.7级的地震基本都有感。这些有感地震分布在东经111°以东地区,呈一向北张口的马蹄形分布,与当地地壳深部的马蹄形构生吻合,湖南省地震震级~烈度统计关系为M=0.93I_0-0.78,所有现今有感地震全部听到地声。
There are one-fifth, sensible earthquakes which recorded by seismograph in Hunan Province,and the earthquakes of M1≥2.7 are basically the sensible earthquakes, which are distributed over, the area of 111°E and are dispersed in the shape of a hoof which opens the mouth in the north side, this tallies with the structure of U-shaped in the local crustal depth. The statistical relations between the magnitude and the intensity are M = 0.93I. -0.78.. All of the present sensible earthquakes occurred after the earthquake sounds are heard.
