A fully integrated and effective response to an oil or chemical spill at sea must include a well planned and executed post-incident assessment of environmental contamination and damage. While salvage, rescue and clean-up operations are generally well considered, including reviews and exercises, the expertise, resources, networks and logistical planning required to achieve prompt and effective post-spill impact assessment and monitoring are not generally well established.The arrangement and co-ordination of post-incident monitoring and impact assessment need to consider sampling design, biological effects, chemical analysis and collection/interpretation of expert local knowledge. This paper discusses the risks, impacts and mitigation options associated with accidental spills and considers the importance of pre-considered impact assessment and monitoring programmes in the wider response cycle. The PREMIAM (Pollution Response in Emergencies: Marine Impact Assessment and Monitoring; www.premiam.org) project is considered as an example of an improved approach to the planning, co-ordination and conduct of post-incident monitoring. 相似文献

A field reconnaissance mission was led to the areas affected by the disaster caused by the Magnitude 7.9 earthquake event
of 15/08/2007 near the city of Pisco in Peru. The main objectives of the mission were to collect data and make observations
leading to improvements in design methods and techniques for strengthening and retrofit, and to assist the phase of reconstruction.
The mission focused on the behaviour of non-engineered structures, in particular those of adobe constructions. The findings
of the mission confirmed that most of the damage was observed on adobe houses constructed with traditional non anti-seismic
techniques which either collapsed or nearly collapsed, causing 519 deaths, 1,366 injuries and more than 58,000 houses destroyed.
The mission also confirmed that buildings constructed according to modern earthquake resistant design standards performed
with no evident damage. All the parties contacted during the mission, especially the EC Delegation, showed particular interest
in the results of the present mission report, which will be taken into consideration when planning the reconstruction phase,
especially of the most distant rural areas, where close collaboration between the Governmental Institutions, International
Organizations, Universities and NGO’s, will be needed to assist the population for the adoption of earthquake resistant designs
in the reconstruction of the destroyed houses. 相似文献

WMN技术用于构建新型地震应急救援无线通讯平台的分析与设想 总被引：2，自引：1，他引：1
传统的WLAN（Wireless LAN无线局域网）因为其单跳的网络特性造成了通讯瓶颈,这也使得其不能很好地满足地震应急救援通讯对效率、准确、安全等特性的要求。一种新型的无线网络形式WMN（Wireless Mesh Network无线网状网）的出现为构建下一代地震应急救援无线通讯系统提供了良好的网络基础。通过对传统地震应急救援无线平台和WMN的介绍,分析了构建新型地震应急救援无线通讯平台的技术指标和可行性,并且给出了平台搭建建议,最后对可能存在的问题以及应用前景进行了讨论。 相似文献

基于TOPSIS评价法的城市应急避难所选址适宜性评价研究 总被引：1，自引：0，他引：1
由于城市中人口高度聚集，一旦发生灾害需疏散受灾居民到应急避难所中，因此应急避难所选址的合理性与适宜性就成为研究的重点。本文从经济性、效率性、公平性、安全性、可达性及环境因素等6个方面出发，选取12个应急避难所选址适宜性评价因子，并构建评价指标体系；利用TOPSIS评价方法构建适宜性评价模型，对研究区42处备选应急避难所的适宜性进行评价，结果表明:优秀级别8个、良好级别10个、中等级别23个、差等级别1个。研究结果可为应急管理部门在选择应急避难所建设位置时提供决策依据。 相似文献

Anticipating the future is a key practice for the management of potential emergencies. Anticipatory action needs the future to become ready-to-hand. Focusing on the logics and practices of anticipatory action the paper discusses the relations between time and space in the context of risk and uncertainty. Spatializations of simulation technologies, preemptive emergency management and anticipatory action aim to disclose and extrapolate the future. In general, infrastructures are technologies which aim to materialize expectations concerning the future. In the case of emergency management infrastructural measures enable and/or constrain practices by inheriting specific logics.The concept of riskscapes (Müller-Mahn and Everts, 2013) poses to be a promising framework to grasp these issues. In our perspective, extrapolated riskscapes treat the future as an already interpreted and symbolically structured world. This involves not only looking at the temporality of riskscapes, but also dealing with geographies of inscribed futurity. Two case studies focusing on emergency management practices of firefighters will be deployed for illustration: the first observes the logics of preemptive emergency management and anticipatory action inscribed into materialities of infrastructures in the context of rail-bound hazmat transports; the second shows how computer simulations for crowded geographies facilitate decision-making and action for policing and crowd management.Instead of treating future in riskscapes as neutral, we highlight the politically situated practices that co-evolve with these technologies and their spatializations. The article discusses the dimension of time within riskscapes to gain a better understanding of the temporalization of space as in simulations and the spatialization of time as in infrastructures of emergency management. 相似文献
