滦县地区的近场地震观测

NEAR-FIELD SEISMIC OBSERVATION IN LUANXIAN SUB-AREA

  • 摘要: 本文对1984年7-8月间在唐山滦县地区的12个观测点上使用PDR-1型数字地震仪进行近场地震观测所得资料初步分析,认为:滦县小区域地震相对密集并与大区域北东向的地震分布不同,震中呈北西向分布并指向7.1级地震震中。人工地震测深资料推断的唐山断裂Ⅰ对唐山地区地震的发生有一定的制约作用,而滦县-乐亭断裂可能为一垂直断裂,它可能控制着滦县小区域的小震活动。

     

    Abstract: The results of the near-field observation in Luanxian sub-area of Tangshart area arepresented in this paper, The observations were carried out at 12 temporary stations equipped with PDR-1 digital recorders during July and August, 1984.#br#The results indicate that the distribution of the earthquakes in Luanxi an sub-area is different from that in Tangshan area. These earthquakes were distributed in NW direction and they directed toword the epicente of the arthquake(M=7.1).#br#The occurrence of earthquakes in Tangshan area may be controlled by thedeep crustal fault I obtained from D. s. s. data. The Luanxian-Leting fault may be a nearly vertical one and it maybe control the microseismic activity in Luanxian sub-area.
