新丰江水库位于广东省河源县境内。1959年水库蓄水后连续发生地震,1962年3月19日发生6.1级强震,十几年来记录到1级以上测定参数的地震二万多次。本文试图通过对新丰江水库区微震震源力学的研究,探讨该区发生地震的应力场和地壳变形。1972年1月至3月设置了流动观测台网,测定地震波动力参数,确定P波节面产状和主
Xinfengjiang Reservoir is located in Heyuan County, Guangdong Province. After the impoundment of reservoirs in 1959, earthquakes occurred continuously, and a 6.1 magnitude strong earthquake occurred on March 19, 1962. More than 20,000 earthquakes with measured parameters above Grade 1 were recorded over a decade. This paper attempts to study the seismic mechanism of the microseism in the Xinfengjiang reservoir area to study the stress field and crustal deformation in the area. January 1972 to March set up a mobile observatory network, determination of seismic wave power parameters to determine the P-nodal origin and the main
