山东及其近海小震群活动特征研究

对山东及其近海30多年来发生的39次小震群资料进行了系统的整理、分析。结果表明:这39次小震群大多分布在断裂带上,发生在2条(或2条以上)断裂交汇部位的占67%,这些容易发生小震群的断层大多为走滑性质的活动断裂,占到86.5%;其中主余型的占57%,双震型的占32%,多震型的占11%,该区震群活动与外围的中、强地震对应率为56%,其中的较显著小震群与外围的中、强地震对应率为71%。对震群与中强地震的间隔时间和间隔距离,以及与区域地震构造的关系进行了初步分析。     

The impact of the 2004 tsunami on coastal Thai communities: assessing adaptive capacity

The suddenness and scale of the 26 December 2004 tsunami and the challenges posed to affected communities highlighted the benefits of their members having a capacity to confront and adapt to the consequences of such a disaster. Research into adaptive capacity or resilience has been conducted almost exclusively with Western populations. This paper describes an exploratory study of the potential of a measure of collective efficacy developed for Western populations to predict the capacity of members of a collective society, Thai citizens affected by the 2004 tsunami, to confront effectively the recovery demands associated with this disaster. Following a demonstration that this measure could predict adaptive capacity, the role of religious affiliation, ethnicity and place of residence in sustaining collective efficacy is discussed. The implications of the findings for future research on, and intervention to develop, adaptive capacity among Thai citizens in particular and collectivist societies in general are discussed.     

Enhancing community-based disaster preparedness with information technology

A critical component of community-based disaster preparedness (CBDP) is a local resource database of suppliers providing physical, information and human resources for use in disaster response. Maintenance of such a database can become a collaborative responsibility among community-based non-governmental organisations (NGOs) and public and private community organisations. In addition to mobilising resources, this process raises awareness within the community and aids in assessing local knowledge and resources. This paper presents the results of a pilot study on implementing a community-based resource database through collaboration with local American Red Cross chapters and public and private community organisations. The design of the resource database is described. The resource database is accessible via the internet and offline using laptops and handheld Personal Digital Assistants. The study concludes that CBDP is strengthened through a combination of appropriate information technology and collaborative relationships between NGOs and community-based organisations.     

Collaborative emergency management: better community organising, better public preparedness and response

Community coordination requires communication and planning of precautions to take when faced with a severe threat of disaster. The unique case of the four Florida hurricanes of 2004--Charley, Frances, Ivan, and Jeanne--is used here to assess community responses to repeated threats of hurricanes. The paper examines how effectiveness in coordinating community disaster response efforts affects future public preparedness. The findings suggest that pre-season planning, open communication between emergency managers and elected officials, and the use of technology all had a significant impact on community responses. The repeated threat scenario indicates that emergency managers must work vigilantly to keep residents informed of the seriousness of a situation. The study describes how emergency managers in Florida countered public complacency during four hurricanes in six weeks. The strategies identified as useful by public managers in the context of hurricanes are applicable to other natural and man-made disasters.     

面向灾害应用的遥感影像融合统一理论体系设计

由于缺乏统一的理论体系指导,目前遥感影像融合研究相对比较混乱。针对像素级融合统一理论框架的思想,指出了遥感影像融合研究的方向和思路,将像素级融合统一理论框架逐步向特征级和决策级推广,着重发展了一套遥感影像融合统一理论体系。在统一体系下,面向灾害监测应用,按照理论研究、方法研究和应用研究的3个层次进行该理论体系的设计。

防震减灾中卫星遥感技术应用分析

卫星遥感技术在减轻自然灾害中发押了十分重要的作用,但也不得不指出,卫星遥感技术在防震减灾工作中,无论在国内或国外均尚未得到有效的应用。这一方面固然是由于地震事件十分复杂,地震孕育和发生的规律尚未搞清,难以发挥卫得遥感技术的作用,另一方面也由中以使用的卫星技术的分辨率还不够高,重复观察的周期长,限制了这一技术在防震减灾工作中的应用。有鉴于近感技术的分辨率还不够高,重复观察的周期长,限制了这一技术在防
