研究了天水地震台附近地区 2次小地震的地震前兆 ,发现地电阻率、自然电位、地下水位、水温、水氡、地温、地应力在震前都有变化。
The earthquake precursors of two small earthquakes in the area around Tianshui Seismic Station were studied. It was found that the resistivity, natural potential, groundwater level, water temperature, water radon, ground temperature and ground stress all changed before the earthquake.
