【摘要】 以固体潮汐理论为基础,讨论了提取各种潮汐、非潮汐参量的计算方法,并依据新疆地区数字化形变观测资料分析了石河子、巴楚震前的短临异常信息。初步获得了各台项异常判别的阈值及该地区近期强震前的短临异常图像。更多还原

【Abstract】 Based on the tidal theory, this paper discussed the method to calculate the tidal and non-tidal parameters, and analyzed the short-term anomaly characteristics before the Shihezi and Bachu earthquakes using the observed digital deformation data in Xinjiang region. Finally, we have preliminary obtained the threshold value for determining the anomalies and short-term anomaly images before strong earthquakes.更多还原
