通过对大连地区遥感影像解译,大连及其周围6000km~2范围内的线性构造可划分为东西向、南北向、北北东向、北东向、北东东向,北西—北北西向、北西西向等7个线性影像带,同时,划分了区内相对隆起区和沉降区及其活动性质、规模。通过对大连地区挽近时期以来的新构造的分析,大连地区地震震中分布有如下规律:地震震中多分布于环形体的上升部位;地貌景观的分界线或衔接处;断裂的交叉处等。据此,对大连地区的地震进行了区域划分。大连市区及其开发区属稳定区。
According to the interpretation of remote sensing image in Dalian, the linear structure within the range of 6000km ~ 2 in and around Dalian can be divided into east-west, north-south, north-east, north- North West and other seven linear image bands, at the same time, the division of the relative uplift and settlement of the area and its nature and scale of activities. Based on the analysis of the new tectonics since the recent strata in Dalian, the epicentral distribution of earthquakes in Dalian has the following rules: the epicenter of the epicenter is mostly distributed in the ascending part of the ring body; the boundary or junction of the geomorphic landscape; the intersection of fractures and the like. Accordingly, the regional earthquake in Dalian has been divided. Dalian urban area and its development zone is a stable area.
