Natural disasters can have dire effects on countries, in the form of human casualties/injuries, infrastructure damage, economic and environmental losses. Earthquakes, in particular, are the most damaging as they are responsible for an annual death toll of over 20K and 20% of the total annual economic losses due to natural disasters. In low-income or developing countries, earthquake impacts are exacerbated, leading to substantial human loss, injuries, homelessness, and population displacement. Irreparable infrastructure damage can also have a great economic impact reaching 20% of a country's gross domestic income, leading to disruption of economic growth and development.Acknowledging this problem, there has been growing national interest in assessing regional seismic risk and loss for major cities. Several countries initiated Disaster Risk Management (DRM) programs which make use of the interdisciplinary advances in science and technology to model the complex interaction of hazard, exposure, and vulnerability and compute loss metrics that can be used by stakeholders and decision-makers to quantify of potential structural, economic, and social consequences, identify critical infrastructure components, outline pre-disaster damage mitigation measures and policies, and planning for post-disaster response protocols.Egypt, a lower-income country and one of Africa's most populated countries, is highly susceptible to the impacts of natural hazards (flooding, rising sea levels, and earthquakes). Several major cities, with populations larger than 5M and overly populated urban centers, are subject to high seismic risk triggered by risk drives such as poverty, climate change, decades of poor construction practices, and absence of municipal oversight. Countries with similar urban conditions, such as Albania and Turkey, experienced a wide extent of damage and losses from recent earthquakes. These countries, and others, allocate extensive funding and resources for DRM. On the other hand, the safety and robustness of Egypt's infrastructure is greatly under-researched. Although several studies investigated the seismic hazard for Egypt's major cities, no attention has been paid so far to either collapse risk assessment or loss and damage estimations (urban exposure, vulnerabilities, and resilience).Egypt-SeReAM will build on and further develop existing DRM methodologies to create such a digital framework for assessing the seismic resilience of Egypt's vulnerable built environment. A partnership between the University of Southampton, three of Egypt's top academic and research institutions will undertake this project combining different disciplines spanning urban planning, seismology, and structural engineering. The project will use the city of Alexandria as a pilot case study to establish the building blocks of the DRM framework concerned with built-environment resilience. The seismic vulnerability of Alexandria's urban center will be assessed, in terms of human, structural, and economic losses due to potential damage to the residential building stock. In the process, spatial urban, geotechnical, structural, and hazard data will be collected and an automated digital framework will be developed to quantify risk and loss under potential earthquake scenarios. The project will employ the geographic information system (GIS) mapping system to describe and communicate the earthquake consequences to the government, academia, industry, and public sectors. This will be packaged within an easily-to-use practice-oriented digital workflow that will assist authorities in making effective decisions for seismic protection measures to minimize potential damage and losses (primarily human, but financial as well) in future earthquakes. Through networking, training, and showcasing activities, the project will promote and specifically target Egypt's short- and long-term resilience to natural disasters, in support of its economic development.

自然灾害可能以人类伤害/伤害，基础设施损害，经济和环境损失的形式对国家产生可怕的影响。尤其是地震是最大的破坏性，因为它们是造成自然灾害造成的年度死亡人数超过20k和年度经济损失的20％以上的死亡人数。在低收入或发展中国家，地震影响加剧，导致人类损失，伤害，无家可归和人口流离失所。无法弥补的基础设施损害也可能产生巨大的经济影响，占国内总收入的20％，导致经济增长和发展的破坏。解决这个问题，国家对评估主要城市的区域地震风险和损失的国家兴趣越来越大。 Several countries initiated Disaster Risk Management (DRM) programs which make use of the interdisciplinary advances in science and technology to model the complex interaction of hazard, exposure, and vulnerability and compute loss metrics that can be used by stakeholders and decision-makers to quantify of potential structural, economic, and social consequences, identify critical infrastructure components, outline pre-disaster damage mitigation measures and policies, and planning for post-disaster response Protocts.egypt是一个低收入国家，也是非洲人口最多的国家之一，非常容易受到自然危害的影响（洪水，海平面上升和地震）。几个主要城市，人口大于500万，人口过多的城市中心，受到风险驱动的高地震风险，例如贫困，气候变化，数十年的建筑习惯差数十年以及缺乏市政监督。诸如阿尔巴尼亚和土耳其等城市状况相似的国家遭受了广泛的损害和损失。这些国家以及其他国家为DRM分配了大量资金和资源。另一方面，埃及基础设施的安全性和鲁棒性大大不足。尽管几项研究调查了埃及主要城市的地震危害，但到目前为止，尚未引起任何关注，以崩溃的风险评估或损失和损害估计（城市暴露，脆弱性和韧性）。Egypt-Seream将在众所周知，并进一步开发现有的DRM方法来创造这种数字框架，以创造出埃及易于建立的环境的数字框架。埃及三家高级学术和研究机构之间的伙伴关系将在城市规划，地震学和结构工程中结合不同学科的项目。该项目将以亚历山大市为试点案例研究，以建立与建立环境弹性有关的DRM框架的基础。亚历山大城市中心的地震脆弱性将根据人类，结构和经济损失评估，这是由于对住宅建筑库存的潜在损害。在此过程中，将收集空间城市，岩土技术，结构和危害数据，并将开发自动化的数字框架以量化潜在地震场景下的风险和损失。该项目将采用地理信息系统（GIS）映射系统来描述和传达与政府，学术界，工业和公共部门的地震后果。这将包装在易于使用的实践数字工作流程中，这将有助于当局为地震保护措施做出有效的决策，以最大程度地减少未来地震的潜在损害和损失（主要是人类，但也是财务上的）。通过网络，培训和展示活动，该项目将促进并特别针对埃及对自然灾害的短期和长期韧性，以支持其经济发展。
