1. The subway can influence the observation of geomagnetism, geoelectric field and ground resistivity around it, but the influencing mechanism is not same.

2. We get the conclusion that geomagnetism and underground water level observations are the fairly good precursor methods.

3. Gauthier began to carry out his geomagnetism observation in Xujiahui Catholic Church of Shanghai.

4. To measure the horizontal component of geomagnetism, the "bifilar balance method" is used(http://), together with an additional adjustable magnetic field to compensate the geomagnetic field.
