摘要
研究了泾阳5.2级地震前的地壳形变、地下水化学参数、地震分布图象和地震波速比的变化特征,结果表明,在震前该区地壳形变、地下流体和地震活动表现出长期、中期和短期的不同特征,具有一定的前兆异常,作出地震预测是可能的。
By studying the temporal eharaeteristies of crustal deformation, u-nderground hydroehemieal parameters, distributions of earthquakes and ratio of P-wave to S-wave before Jingyang earthquake with ML = 5.2, it is found that the crustal deformation, underground fluid and seismieity in this region exhibits different properties in long, medium and short terms before the earthquake. Thus, some anomalies do exist before the earthquake, and the forecast of the earthquake may be made.
