汶川Ms8.0地震余震时空变化及影响度分析
|
摘要
本文对汶川Ms8.0地震及其余震的原因进行简要回顾后,根据主震之后至6月2日0时192次Ms4.0以上的余震的统计结果进行时空变化及影响度分析,分别从震型、震源深度、空间位置-震级及影响度、频次-时序和震级-发震时间段四个方面以图表的形式分析阐释余震的发震规律和影响程度。通过本文分析研究,进一步揭示汶川地震整个过程的活动规律,对其后余震的影响进行剖析,进而为在目前全球地质活动活跃期背景下,对中国西部地震灾害环境与可持续发展的研究提供参考意义。
This paper is conducted by the brief review analysis reason of the Wenchuan Ms 8.0 earthquake and the aftershocks,and then the analysis on the temporal & spatial variation and influence degree are conducted according to the statistical results from May 12th to the June 2nd. The regulations of the aftershocks,as well as its influence degree,are displayed respectively by the ways of graphs and tables in the following facets of the shock type,focal depth,spatial position-magnitude and influence degree,frequency-time sequence and magnitude-occurrence time. By this analysis,the regulation of the overall progress of this earthquake could be described,and the influence produced by the aftershocks could also be analyzed,moreover the results of this paper could provide some reference for the research on the western earthquake disaster environment and the sustainable development in China under during the present active period of the global geological activities.
