Abstract The problem of reference value confirmation by using the traditional methods to extract seismomagnetic information from geomagnetic survey data is discussed with observational examples. A new method, which uses the mean value of F at crelible sites in the measuring region as reference value of geomagnetic field, is presented. The method increases the ratio of signal to noise, and makes the extraction of abnormal information more rational.
Key words :
mobile geomagnetic survey
