The regional anomaly strenches northwestly and north-eastly in high intensity and clearness and good register.
区域异常北西、北东向展布，强度高、清晰而套合性好。

The difference between the lithosome shape, distribution of kimberlite and the physical natures of adjacent rock decides the size, intensity of anomaly and the reflecting degrees.
金伯利岩岩体形状空间分布与围岩的物性差别，决定了异常大小强弱、反映明显程度；

By processing data of precursory earthquakes, we try to find the useful anomaly information from the data of strain and total geomagnetism intensity.
