News GEM - EDF/CEA technical cooperation aims to enhance the exchange of scientific and technical knowledge on earthquake hazard By: Oct 7, 2019 Share Facebook LinkedIn Électricité de France (EDF), a nuclear electric power generation company and France’s Alternative Energies and Atomic Energy Commission (CEA) are the latest to join GEM as Project Partners, after a series of technical meetings and workshops since 2018. The partnership which spans three years, will focus on the integration of new ground motion prediction equations (GMPEs) into the OpenQuake engine necessary for the calculation of earthquake hazard in metropolitan France, and capacity development through secondment of EDf and CEA researchers at GEM Pavia office and training on OpenQuake. “This partnership does not only strengthen GEM’s commitment to the scientific advancement of earthquake hazard analysis using the OpenQuake engine, but also promotes a two-way sharing of knowledge and skills for the advancement of earthquake hazard assessment to critical infrastructure,” says John Schneider, GEM Secretary General after signing the agreement recently. Priority research areas in probabilistic seismic hazard assessment (PSHA), and concrete scientific and technical content and activities of the partnership will be defined on a yearly basis to ensure that the program for the succeeding year builds upon the achievements of the previous one. Prior to the agreement, GEM conducted a 4-day training on OpenQuake for EDF and CEA scientists and engineers earlier this year at the EDF lab - Paris Saclay, France. The results of that training formed the core of the collaboration between GEM and EDF/CEA. No images found. GALLERY 1/0 VIDEO RELATED CONTENTS

Publications Probabilisitic Seismic Hazard Analysis: Issues and Challenges from the GEM Perspective Share Facebook LinkedIn Download 2016 | Probabilistic Seismic Hazard Analysis (PSHA) is a practical framework, with a sound theoretical basis, used globally for assessing seismic hazard at different spatial scales to suit many different objectives. Soon after its establishment in the late 1960s, communities involved in PSHA for national seismic hazard mapping and for the siting and design of nuclear facilities led the development of this scientific-technical discipline. In recent years, other scientific and commercial sectors introduced specialised modelling approaches such as the ones shaped by the community serving the financial sector and, most recently, the research groups involved in infrastructure and man-made earthquake hazard and risk analysis.

Publications Back to Normal report Share Facebook LinkedIn Download 2017 | Report Given the high level of earthquake risk in California, all communities need to be prepared to respond to and recover from the impacts of a potentially devastating earthquake. Although there has been significant research on the estimation of direct economic losses immediately after an earthquake, there has not been enough research about long-term recovery, and even less in the development and application of computer simulation models. This is to some extent because data on building repair and recovery times from past earthquakes have not been systematically documented (Comerio M. , 2006). Moreover, the models developed so far have not successfully captured the complexity of the recovery process. Recovery depends on many factors (such as the socio-economic conditions of the affected area) that are usually difficult to measure, understand and apply to predicting or modelling the recovery process.

News IDF Report identifies how barriers to Global Risk Understanding can be overcome By: Oct 20, 2020 Share Facebook LinkedIn The Insurance Development Forum (IDF), a partnership led by the insurance industry and supported by the UN, World Bank, NGOs and other international organisations, is calling for an international collaboration to share and propagate capabilities in disaster risk understanding where it is needed the most. This call to action is the message of the IDF’s latest white paper – – a truly cross-sector report bringing together risk expertise from more than 30 organisations across private sector, development agencies and specialists, academia and international NGOs. The paper demonstrates how the adoption of open risk modelling principles and frameworks can help countries and cities integrate invaluable local knowledge with global research, and most importantly develop their own view of risk for strategic risk management and operational risk finance. The report assesses the powerful contribution of risk quantification in the context of the 17 , and how the use of open risk analytics principles and platforms can overcome cost and other barriers to access, while increasing confidence in the analysis. This empowering capability is critical as vulnerable economies seek to build social, environmental and financial resilience in the face of increased climate risk, pandemic and other threats. Specific country case studies build the case for local empowerment through building national and city risk functions. A deeply evidence driven chapter describes the distinct experience of women and girls in disasters, and how gender considerations can – and must - be integrated in the process of understanding and managing risk. Providing compelling evidence from all sectors and from across the globe, the paper recommends that the way to accelerate risk understanding at scale is through public, private and academic collaborations, made possible through shared use of open source platforms and data standards. The private sector has developed risk understanding as a survival skill and stands ready to work with sovereign ministries, development partners and humanitarians in strategic risk prevention, residual risk transfer and anticipatory action. Critically, this will build a shared language of risk across providers and users of risk capital. Between them, the expert contributors identify that disasters and climate risk are intensifying, and their impacts – as we have seen recently with COVID-19 – are a global concern. As the authors suggest, to better prepare for these scenarios we need to move from managing disasters to managing the risk itself. “Our subjective personal experience and observations will always be a factor in complex decision-making, and we all know that no model will ever be completely correct. However the public-private programme applying open source principles and standards, where risk analytics can become accessible as a strategic resource to all nations and cities at risk.” “Development is about empowerment; risk owners are understandably keen to move from aid dependency to sustainable local capacity, capable of responding to the differentiated needs of communities, genders and vulnerable groups. However it is hard for a nation or city to achieve this while barriers remain to building local risk understanding, and to integration of local experience and research. Governments and cities increasingly need to integrate strategic risk thinking into their resilience planning and financing frameworks, but to do so they need accessible tools and methodologies. The re/insurance sector can bring significant risk modelling and risk management expertise to help unlock sustainable investment. This paper shows how cross-sector collaboration, open standards and enabling technology can harness these strengths for public good and economic development.” "This report relates compelling evidence that women and men face different climate and disaster risks and vulnerabilities. People centred metrics are crucial to accelerating progress towards the Sustainable Development Goals. To ensure risk prevention and resilience programmes are gender-responsive, the report shows the value of gender-information and sex-disaggregated data. Empowering more women in technical and leadership positions will be key to generate and apply these insights: from national climate and disaster risk planning to the design, implementation and regulation of all types of risk transfer mechanisms." ----- END ----- The IDF is a public/private partnership led by the insurance industry and supported by international organisations. The IDF was first announced at the United Nations Conference of the Parties (COP21) Paris Climate summit in 2015 and was officially launched by leaders of the United Nations, the World Bank and the insurance industry in 2016.
