摘要
在新编全国地震区划图潜在震源区划分工作中,采用了三级划分的技术思路,即在地震统计区内先划分出地震构造区,以控制地震统计区内地震构造和地震活动的差异性,然后,在地震构造区内再进行潜在震源区划分。地震构造区划分是新编全国地震区划图潜在震源区划分工作中的一个关键环节。本文论述了地震构造区的定义、作用、划分原则和依据等。介绍了中国东部地区地震构造区划分方案,并以东北地震区和华南沿海地震带为例,对地震构造区划分方案进行了详细论述。
We have adopted the three-level delineation principle in identifying potential sources of earthquakes for updating the national seismic zoning map of China.First,we delineated seismotectonic provinces in seismic statistical zone for distinguishing different seismotectonics and seismic activity,and then,identified potential sources of earthquakes in seismotectonic province.The delineation of seismotectonic provinces is a critical technology in updating the national seismic zoning map of China.In this paper we summarize the definition,purpose,and delineation principles of the seismotectonic province,introduce the scheme of seismotectonic provinces in the East China,describe delineation scheme of seismotectonic province of the Northeast China seismic zone and the costal seismic belt in Southeast China.
