| 摘 要： | 研究了钻孔应变年变畸变型异常及指数型异常对地震震级的估计问题,认为年变畸变型异常对大震有较高的映震性能.研究了异常幅度和震中距、时间分布和震级关联问题,结果表明,在时间小于45天时,震级和发震时间呈反比,在时间大于45天时,震级和发震时间呈正比.

| Abstract: | The question of earthquake magnitude estimation by the aberration-type anomalies of yearly change and exponent-type anomalies of borehole strain was studied, the result showed, the aberration-type anomalies of yearly change was good on earthquake prediction. The relation between anomaly range and the epicenter distance, the time distribution and earthquake magnitude were studied, the result showed, it was inversion ratio relation between earthquake magnitude and its developing time in the less than 45 days; in the more than 45 days, it is direct ratio relation between earthquake magnitude and its developing time. |
