摘要
By a comparative analysis of the data of underground water level simultaneously observed by analog seismometer and the digital one at four stations in Yunnan Province, the authors find that the two kinds of data have the following relations: close inherent quality,high correlativity, the same time-variation shape,and the similar co-seismic response. In view of its advantages of small disturbance, timely information and easy maintenance, it is concluded that the digital observation can replace the analog one.
