Earthquake precursornBefore the earthquake refers to the abnormal phenomenon before the earthquake occurred, under the ground stress of the rock body, in the process of gradually accumulating and strengthening the stress strain, it will cause the source of the earthquake and the significant changes in the earthquake, the surface of the surface, the geomagnetic and geomorphous power, and the geomagnetic and geographical power. , Gravity and other physical abnormalities, groundwater levels, hydraulic chemistry, animal abnormal behavior, etc. Generally, the phenomenon of abnormal changes that are associated with the earthquake and the occurrence of earthquakes are a precursors to the earthquake (also known as the abnormal earthquake). It includes two categories: seismic micro -abnormalities and earthquake macro abnormalities.
