STUDY ON THE ANOMALIES RECORDED BY VS PERPENDICULAR PENDULUM
though perpendicular pendulum and horizontal pendulum record the same physical quantity, but the difference in anomaly image is very large.There are four factors to cause anomaly for perpendicular pendulum:(1)anthropogenic factor;(2)instrumental factor;(3)seismic factor;(4)bad location of station factor.It is significant to recognize anomaly from the recorded curves.
