摘要
应用中国大陆地区地震活动的地震学参数(如大震烈度图、综合等震线、余震分布、震源尺度、地震矩、地震应变、能量、震源机制解和震中分布等,通过综合集成,刻画了我国陆区地震活动性的空间展布格局。并将其与中国大陆活动地块及其边界相比较,发现中国7级以上强震活动基本上都集中在活动地块的边界上,这对进一步了解活动地块的运动性状、探讨地块之间相互作用及与强震发生的关系具有重要意义。
Applying seismological parameters in China′s continent, such as intensity map of strong earthquakes, comprehensive isoseismic line map, aftershock distribution, the focus scale, seismic moment, seismic strain, energy, focal mechanism and epicenter distribution, et al., and through comprehensive integration, the seismic activity characteristics in China's continent are described. Comparing with the active blocks and their boundaries, it has been found that most of M>7 earthquakes distribute along these boundaries, which will be of great significance to deeply understand the characteristics and study the interaction between blocks and the relation with strong earthquakes.
