March 1990 Hailstorm Damage in Sydney,Australia

On 18 March 1990, an intense hailstorm in Sydney, New South Wales, Australia caused insured damage valued at A$million – the third most expensive loss event in Australian insurance history.While damage was widespread with claims for buildings spread across more than 130 postcodes, 20% of the claims came from just two postcodes. The proportion of dwellings of brick construction that made a claim was significantly less than the proportion of policies for this type of construction. Fibro (fibre-cement), timber and aluminium-clad dwellings are more likely to sustain damage than brick buildings in this type of storm.Hail caused the majority of damage to exterior building items while water damage more commonly affected interior building items and contents. While the repair of Interior building items such as ceilings and walls cost more than contents damage on average, the repair/replacement costs of contents contributed more to the total costs. Damage to window glass and roofs together made up more than 50% of the total claim.

华北南部地区——古生界构造演化及其油气远景

华北南部地区的地质演化与华北其他地区一样，经历了结晶基底形成，中一晚元古代台内裂谷发育、古生代稳定地台沉积和中一新生代活化等发展过程。但本区受秦岭褶皱带构造活动的强列影响。因而具有相对独特的构造演化特征和油气控制条件。早寒武世中期，古秦岭海槽伸展扩张，沉积了一套全区广泛分布的以碳酸盐岩为主夹泥页岩的地层；晚寒武世开始，古秦岭海槽向北俯冲挤压，在本区南部出现一个平行于海槽的大陆边缘隆起；中奥陶世发生     

对近年来地震危险区预测效果的评估

采用R值评分方法，对中国地震局地球物理研究所2001—2004年度划定的全国地震危险区进行了评估，2001—2004年度的R值分别为0．265、0．182、0．293、0．404。近两年的R值相对高些，为了排除随机成分，做了相应的随机预报试验检验，并对地震落入危险区的随机概率作了估计。结果表明，4个年度的R值明显高于随机预报，除2002年度外，地震随机落入危险区的概率很低，不到2％。这说明中国地震局地球物理研究所实际地震危险区划分取得了一定的效果，且逐年提高。     

利用高分辨率卫星影像进行地震损失评价所需的城市特征识别

高分辨率卫星影像已经在一些国家的民用领域得到应用。利用高分辨率卫星影像来收集地震损失评价所需要的各类城市信息不仅高效和有较好的时间分辨率，而且它可以减少以往所必需的大量的代价高昂且费力的城市调查。基于在印度城市台拉登所做的研究，讨论了如何利用高分辨率卫星影像进行城市特征识别的一些问题，同时也简单论述了利用GIS／RS软件综合所得的数据以便用于地震损失评价的方法。

Earthquake Disaster Management and Insurance

As one of the most powerful tools to reduce the earthquake loss, the Earthquake Disaster Management [EDM] and Insurance [EI] have been highlighted and have had a great progress in many countries in recent years. Earthquake disaster management includes a series of contents, such as earthquake hazard and risk analysis, vulnerability analysis of building and infrastructure, earthquake aware training, and building the emergency response system. EI, which has been included in EDM after this practice has been done for many years, include these contents: insurance model, financing. This paper presents the development of china in EDM and EI. The main contents include: (1) the statue and trend of earthquake disaster management and insurance in china; (2) the progresses and new methods about the seismic risk zonation and vulnerability analysis, and the future developing trend, the application of GIS in earthquake disaster assessment is introduced; (3) the way and illustration in building the earthquake disaster e     

21世纪中国地质灾害防治形势与减灾战略思考

文章论述了21世纪中国地质灾害减灾面临的形势是既存在许多有利条件又存在多方面困难而面临严重挑战。提出21世纪地质灾害减灾战略：1．建立地质灾害防治安全维护体系；2．优先安排西部地区地质灾害防治工程，实施地质灾害风险管理；3．建立矿山地质灾害防治监督管理体系；4．城市地质灾害防治与土地利用相结合；5．加强我国地质环境监测与网站建设；6．针对地质灾害区域分布规律，采取分区减灾对策；7．加大地质灾害防治投入力度。
