山西河津4．8级地震临汾地震台数字形变资料异常特征及同震响应分析

摘要

Abnormal variation characteristic and difference of coseismic response of deformation data at Linfen Seismological Station before and after the Hejin, Shanxi earthquake of M4.8 are analyzed. The result indicates that observed data of each instrument exists distinct anomaly and that each instrument exists distinct difference in response to the same earthquake because of the difference of frequency response range of the instruments.%文章对山西河津4．8级地震前后临汾地震台各形变资料异常变化特征及同震响应的差异性进行分析，结果表明，震前各仪器观测资料均存在明显的异常，由于仪器频率响应范围的差异性，各仪器对同一地震的响应也存在显著不同。
