中文摘要:

用地震参数,在 Tianshan 的各种各样的 seismotectonic 区域的地震活动的特征在这份报纸被学习。这些区域正在通过地震精力累积的不同阶段。这些区域的当前的地震风险层次被地震活动的构造运动率和强烈地震的复发间隔综合地分析。我们 preliminarily 在积累阶段的不同地震精力学习了地震活动的特征。结果证明在 Tianshan 区域的各种各样的 seismotectonic 区域的地震活动的特征被影响,不是仅仅由地区性的构造运动,而且由精力积累各种各样的地震 tectonics 的舞台。在强烈构造运动区域,估计它积累以便预言潜在的地震大小的上面的限制的精力的阶段是重要的。在不太强烈的构造运动区域,估计精力累积的阶段将帮助我们认出潜在的强烈地震的危险水平。在南部的 Tianshan 的 seismotectonic 区域到达了的学习表演精力累积中间阶段、迟了阶段,与一项更高地震的活动并且这样更高地震的危险水平比那些在北、中间的 Tianshan。南部的 Tianshan 的地震风险直到 Ms7.0,当中间的 Tianshan 的直到 Ms6.0,北 Tianshan 的仅仅在 Ms5.0 6.0 附近时。

英文摘要:

Using seismic parameters, the characteristics of the seismic activity in various seismotectonic regions of Tiaushan were studied in this paper. These regions are going through different stages of seismic energy accumulation. Current seismic risk levels of these areas were analyzed synthetically by the tectonic movement rates, as well as the characteristics of the seismic activity and the recurrence intervals of strong earthquakes. We preliminarily studied the characteristics of seismic activity in different seismic energy accumulating stages. The result shows that the characteristics of the seismic activity in various seismotectonic regions of the Tiaushan area are influenced, not only by the regional tectonic movement, but also by the energy accumulating stage of various seismic tectonics. In the intense tectonic movement areas, it is important to estimate its stage of energy accumulating in order to predict the upper limit of the potential earthquake magnitude. In the less intense tectonic movement areas, the estimating of the stage of energy accumulation will help us recognize the dangerous level of the potential strong earthquake. The study shows that the seismotectonic regions in southern Tiaushan have reached the mid-stage and late-stage of energy accumulation, with a higher seismic activity and thus a higher seismic dangerous level than those in the northern and middle Tiaushan. The earthquake risk of southern Tianshan is up to Ms7.0, while that of the middle Tiaushan is up to Ms6.0 and that of northern Tiaushan is only around Ms5.0 - 6.0.
