国际地震预测研究进展与动向     

朱传镇 《国际地震动态》1995,(5):5-9

地震预测是世界公认的科学难题，本文对地震预测的难点作了简要分析，并指出其实质在于缺乏对地震发生规律性的认识。文中较详细地介绍了近些年来欧洲、日本、美国和俄罗斯在地震预测研究方面的进展。实际情况表明，国际上虽对地震预测研究还存在着种种不同意见，但地震预测研究仍在扎扎实实地取得进展，然而，要期望取得突破，尚需做出长期不懈的努力。  相似文献   

必须重视大型石油储罐的抗震问题   总被引：2，自引：0，他引：2  

韦树莲 《国际地震动态》1995,(3):17-21

地震灾害是各种自然灾害中最大的一种灾害，而大型石油储罐则是石油化工设备中震害最大设备，因此必须重视大型油罐的抗震问题，本文从油罐的几何形状的荷载特征等方面说明了油罐震害之所以特别大的主要原因；指出了油罐的主要震害；并从四个方面说明了油罐的抗震理论是非常复杂的。  相似文献

Evaluation of Earthquake Losses and Establishment of a Corresponding Database System   总被引：1，自引：0，他引：1  

Li Shuzhen  Yin ZhiqianInstitute of Engineering Mechanics. SSB  Harbin China 《中国地震研究》1995,(3)

After the Datong-Yanggao earthquake (October 1989),a special team was organized for the first time by the SSB of China to start the work of earthquake damage evaluation for the purpose of providing the government with a scientific basis for disaster relief.The result of the evaluation played an important role in speeding up rehabilitation and reducing damage losses in the earthquake area.Based on the evaluation of earthquake damage from the Datong-Yanggao earthquake and recent research results,this paper presents a method for quick evaluation of earthquake damages,introduces software entitled EDEP (earthquake damage evaluation program) for evaluating earthquake damage,and cites a case to explain the main function and application of the EDEP.Finally,for a quicker evaluation of earthquake damages,the paper also proposes the establishment of database systems of earthquake damage evaluation in the emphatically monitored areas and ways to build up such database systems.  相似文献   

Edge wave and non-trapped modes of the 25 april 1992 Cape Mendocino tsunami     

F. I. González  K. Satake  E. F. Boss  H. O. Mofjeld 《Pure and Applied Geophysics》1995,144(3-4):409-426

The 25 April 1992 Cape Mendocino earthquake generated a tsunami characterized by both coastal trapped edge wave and non-trapped tsunami modes that propagated north and south along the U.S. West Coast. Both observed and synthetic time series at Crescent City and North Spit are consistent with the zero-order edge wave mode solution for a semi-infinite sloping beach depth profile. Wave amplitudes at Crescent City were about twice that observed at North Spit, in spite of the fact that the source region was three times farther from Crescent City than North Spit. The largest observed amplitude was due to an edge wave which arrived almost three hours after the initial onset of the tsunami; since such waves are highly localized nearshore, this suggests that the enhanced responsiveness at Crescent City is at least partly due to local dynamic processes. Furthermore, the substantially delayed arrival of this wave, which was generated at the southern end of the Cascadia Subduction Zone, has significant implications for hazard mitigation efforts along the entire U.S. West Coast. Specifically, this study demonstrates that slow-moving but very energetic edge wave modes could be generated by future large tsunamigenic earthquakes in the CSZ, and that these might arrive unexpectedly at coastal communities several hours after the initial tsunami waves have subsided.  相似文献
