摘要:

2004年12月26日苏门答腊安达曼MW 9.1地震及印度洋超级海啸,以及2011年日本东北MW 9.0地震及海啸与核泄漏,给人类带来了巨大的灾难。这两次灾难的接连发生充分暴露了迄今我们对于地震发生规律的认识水平还是很低的,启示我们需要继续加强对地震发生的规律性与地震预测预报的研究。在地震危险性评估中,要努力克服经验性方法的局限性,加强地应力测量以确定断层接近破裂的程度,更直接地估计地震危险性;要最大限度地运用地震、大地测量、地质、地貌等所有可资利用的资料,尽快将学术研究成果应用于防灾减灾实践。要重视不同观测资料的整合集成。要加强学科与学科之间的交叉渗透,自然科学与社会科学之间的合作交流,以及科学界与决策者和社会公众的相互沟通。要加强在海域对地震、海啸的多学科、多手段的监测工作,加强地震破裂过程复杂性的理论与应用研究,提高对地震、海啸(包括局地海啸)的监测、预测预报与预警水平。

Abstract:

The December 26, 2004 SumatraAndaman earthquake of MW 9.1 and the ensuing Indian Ocean tsunami and the March 11, 2011 Tohoku, Japan, earthquake of MW 9.0 and the ensuing tsunami and nuclear leakage resulted in tremendous disasters to the humankind. The consecutive occurrence of the two disasters fully exposed that up to the present our knowledge of the regularities of earthquake occurrence remains in a poor state, and showed that studies on the regularities of earthquake occurrence and the earthquake prediction/forecast should be continuingly intensified. In earthquake hazard assessment, efforts should be made to overcome the limitations arose from the empirical methods, and stress measurements should be enhanced to directly determine to what extent the fault approaches to rupture so as to directly evaluate earthquake hazard. All available data, such as seismological, geodetical, geological and geomorphological data, should be used to the full extent in earthquake hazard assessment, and the results from scientific research should be turned into practice to the best in earthquaketsunami disaster prevention and mitigation. Special attention should be paid to the integration of various data. Interdisciplinary collaboration in scientific research, cooperation between natural and social sciences, and communication between scientists and decisionmakers/public should be greatly strengthened. Multidiscipline and multiapproach earthquaketsunami monitoring including local tsunami monitoring, in undersea area and theoretical and applied studies on the earthquake rupture process should be intensified to promote our ability of earthquaketsunami monitoring, prediction/forecast and early warning.

Key words:  SumatraAndaman earthquake, Tohoku, Japan, earthquake, tsunami, nuclear leakage, earthquake hazard, earthquake prediction/forecast, earthquaketsunami early warning
