贵州地震的分布特征
|
摘要
根据地震分布密度、控制地震发生的构造的差异,将贵州地震平面分布划分为威宁—晴隆区(A区)、遵义—贵阳区(B区)和铜仁—榕江区(C区)3个区;A区和B区以垭都—紫云断层为界,B区和C区以松桃—独山断层为界;A区、B区和C区的地震分布分别为80%、15%和5%。贵州地震震源深度显示都属于浅源地震,总体主要集中在7～11km;B区分布在30km以浅深度内;A区主要在20km以浅深度内,在20～70km也有地震发生。1900年～1975年,4级以上地震活跃期为1906～1919,1928～1941,1948～1955,1963～1974;1975～2011年,3级以上地震活跃期为1978～1989,1993～2000,2003～2011。
According to the earthquake distribution density and tectonic difference of earthquake control occurrence, the earthquake distribution can be divided into Weining-Qinlong area (Area A), Zunyi-Guiyang area (Area B) and Tongren-Rongjia area (Area C). Demarcation line of Area A and Area B is Yadu-Ziyun Fault, demarcation line of Area B and Area C is Songtao-Dushan Fault. Earthquake distribution of Areas A, B and C is respectively 80 %, 15 % and 5 %. The focal depth shows that earthquakes of Guizhou are all shallow focus earthquakes, generally focusing on 7~11 km. The focal depth of Area B is less than 30 km and the focal depth of Area A is less than 20 km, some of them are 20~70 km. There were 4-degree seismic active periods from 1900 to 1975, namely, 1906~1919,1928~1941,1948~1955 and 1963~1974. There were 3-degree seismic active periods from 1975 to 2011, namely, 1978~1989,1993~2000 and 2003~2011.
