【摘要】 用易县地震台潮汐形变观测资料分析了青海昆仑山口西 8.1级地震时同步出现的同震阶跃的特征。可以看出 ,DSQ型水管仪、VS型垂直摆、TJ 2C型体应变仪的同震阶跃呈负值变化 ,而SS Y型伸缩仪之EW分量和NE分量呈正值变化。更多还原

【Abstract】 On the basis of the tidal observation data of Yixian station, this paper quantitatively describes the characteristics of the synchronous co-seismic step phenomenon of different observation measures when the %M%s8.1 earthquake ocurred in Kunlun Mountain Pass.It is indicated that the co-seismic steps of water tube tilt of DSQ type,vertical pendulum of VS type and body strain meter of TJ-2C type have tranformed in negative value and that of EW and NE branches of extensometer of SS-Y type have changed in positive value.更多还原
