Landslide susceptibility and hazard mapping in Australia for land-use planning — with reference to challenges in metropolitan suburbia     

Andrew R. Leventhal  Greg P. Kotze 《Engineering Geology》2008,102(3-4):238

This paper provides an overview of the history and current status of landslide susceptibility and hazard mapping for land-use zoning in Australia. It also describes a case study of landslide hazard mapping in a medium density, coastal, suburban residential area of metropolitan Sydney, New South Wales, Australia, with relatively steep terrain. Issues covered include identification and mapping of existing and potential landslides, and susceptibility and hazard zoning for regulatory management and land-use planning. The method involves application of the principles contained within the AGS (2000) guideline, and as updated by the AGS (2007 a,b,c,d,e) suite of guidelines.  相似文献

湖南膨润土矿床成因类型及矿床实例   总被引：1，自引：0，他引：1  

陈民苏  车勤建 《湖南地质》1990,9(2):29-38

根据成矿地质条件及矿床特征,笔者将湖南省膨润土矿床归纳为四种成因类型:即滨海火山碎屑沉积矿床、内陆湖泊沉积矿床、浅海沉积矿床及风化残余矿床。文中对不同成因的矿床特征进行了简要介绍,并对湖南膨润土矿找矿标志进行了初步归纳。最后在全省范围内划分出六个找矿远景区,以期引起同行们的注意。  相似文献

The Best Combination Methods and Applied Research of Seismic Prospecting for Active Faults in Urban Areas     

Fang Shengming 《中国地震研究》2007,21(3):236-244

This paper introduces briefly the basic principles of various seismic prospecting techniques and working methods according to nationwide practices of seismic prospecting of active faults beneath big cities in recent years.Furthermore,it analyzes the application range of different seismic prospecting methods,main achievements and solved problems,and discusses the best combination of seismic exploration methods for detecting crustal structures and locating the faults used in the present stage,that is,to trace faults which are at depths of hundred of meters underground using shallow seismic investigation,to detect the faults which are above basement(at a depth of kilometers) using high resolution refraction sounding,and the deep crustal faults using combined seismic prospecting methods of reflection seismic sounding and wide-angle reflection/refraction sounding,and furthermore,to use the 3-D deep seismic sounding method to obtain 3-D velocity structures beneath urban areas.Thus,we can get information about fault attitude and distribution at different depths and a complete image of faults from their shallow part to deep part using the combined seismic exploration method.Some application examples are presented in the article.  相似文献   

中国古代一些地震前的植物异常     

万才淦 《华南地震》1992,12(4):60-63

作者查阅中国历史文献600余种,从中收集到700处与地震有关的植物异常记录。本文报导其中近40次震前植物异常实例,对震前出现植物异常的原因作了分析,认为旱、涝、温度、地下水、前震、放谢性物质、地磁场变化等可能是引起震前植物异常的中介因素。  相似文献
