本文分析了1982年1月25日广东崖县Ms4.0级地震的台网观测及现场调查资料发现:该震的等震线长轴与当地最显著的构造——两条东西走向的大断裂不一致,两者近于直交;利用14个台所记录的P波初动符号解得的震源主压轴与区域构造应力场的主压轴近于直交;而且震源主压轴的仰角高达55°,大大高于东南沿海区震源主压轴仰角的平均值。据此并联系
This paper analyzes the station observation and field survey data of the Cliff of Ms4.0 of Yaxian, Guangdong Province on January 25, 1982. It is found that the major isoseismic line of the earthquake and the most prominent structure in the area - two large faults And the two are close to normal. The main pressure axis of the source and the tectonic stress field of the source obtained by using the P wave initial sign recorded by 14 stations are close to normal; and the elevation angle of the main pressure axis of the source is as high as 55 ° The average value of the elevation of the main finale of southeastern coastal areas. According to this and contact
