RESEARCH ON APPLICATION OF UNIFORM TEMEPRAL-SPATIAL ELEMENTS FITTING OF GEOMAGNETIC FIELD IN PREDICTING SEISMIC RISK ZONES

In this paper,using the data of 12 geomagnetic observatories and applying the method of uniform temperal spatial elements fitting,the theortical model of geomagnetic field has been obtained.After removing the normal field and the space disturbance,the distribution of abnormal field in some locations have been drawn.The distribution contour lines are consistent with the stress distribution and tectonics.The prelimanary results show that this mothod is of vast prospect in earthquake prediction.
