天水地震台附近2次小地震的前兆
PRECURSORS OF TWO SMALL EARTHQUAKES NEAR THE SEISMOLOGICAL STATION OF TIANSHUI
【摘要】 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。
【Abstract】 The precursors of two earthquakes near seismological station of Tianshui are analysed in the paper.The earth-resistivity,nature electric potential,level of underground water,water temperatute,radon in groundwater,geotherm and ground stress are changed before earthquakes.
