【摘要】 利用93个钻孔应变台站记录的日本9.0级地震的观测资料,计算出各个台站记录的面应变的应变阶,通过同震应变阶的张压性变化显示,日本9.0级地震可能对华东、华北和东北地区的影响以张性变化为主。利用稳定时段的观测资料进行理论固体潮标定,得到实际应变阶,利用同震应变阶分析中国大陆主要活动断裂可能受到日本9.0级地震的影响程度时,没有发现明显规律。更多还原

【Abstract】 Using the data of M_s9.0 earthquake in Japan recorded in 93 borehole strainmeter stations, we calculate the strain step of the plane strain. The results show that the changes of strain step are mainly tensile in the east, north and northeast regions of China. According to the theoretical earth tide calibration with aseismic, stable periods of the observation data. We get the actual strain step, and find no obvious trends in the analysis of major active faults in China when the earthquake-affected.更多还原
