Global Earthquake Maps Global Earthquake Risk and Covid Map VIEWER PDF PNG CONTRIBUTORS DOCUMENTATION References ​ TECHNICAL DESCRIPTION EXPERIMENTAL map for demonstration purposes only This map presents COVID-19 statistics released by Johns Hopkins University Coronavirus Resource Center over the GEM Global Risk Layer depicting earthquake risk from the GEM Global Earthquake Model (2018). The COVID-19 data shows cumulative number of new cases reported. Click on dots on the map to display a graph of COVID-19 cases as a function of time. The earthquake risk map depicts average annual loss (AAL) over cells of about 100 km squared, expressed in terms of potential damage to buildings in terms of square meters of building floor area. The combined map indicates areas where a damaging earthquake could cause increases in COVID-19 cases due to displacement of people from damaged buildings or where health care systems may be further stressed due to human injuries. GEM’s global model and underlying data and models for social and physical vulnerability can be used to estimate the additional risk in the event of an earthquake and to identify those places at greatest combined COVID-Earthquake risk.

PRESS RELEASE ----- GEM Conference 2023: A Milestone Event Showcasing Advances in Global Earthquake Hazard and Risk Maps, Models and Databases ----- ​ ​ Bergamo, Italy - June 13, 2023 ​ The Global Earthquake Model (GEM) Foundation, a leading organisation in earthquake hazard and risk modelling and assessment, is set to release its new version of the global earthquake hazard and risk models, maps, and databases. This ground-breaking event will take place as the centrepiece of GEM’s international conference in Bergamo, Italy, on June 13th. Gathering leading researchers and risk management experts, the conference aims to propel the world towards greater earthquake resilience and discuss recent developments in the field. ​ Since GEM released the Global Earthquake Hazard and Risk maps to the public in December 2018 , the data and maps have been recognised as a major milestone in establishing a unified and global understanding of seismic risk. Downloaded thousands of times and embraced by industry experts, these maps have provided valuable insights into earthquake-prone regions worldwide. Building upon this success, GEM continued to develop new products such as Atlas 1.0 , an interactive global seismic hazard map, and comprehensive hazard maps available through GEM and distributor platforms. ​ "We are excited to host this important conference and bring world-leading experts in earthquake hazard and risk research, together with partners across the public and private disaster risk management and risk reduction sectors," said John Schneider, GEM Secretary General. "By sharing our knowledge and expertise, we can work together to reduce the impact of earthquakes and build more resilient communities around the world." ​ What’s new ​ In the forthcoming 2023 version of the global seismic hazard model, GEM has made substantial enhancements. Marco Pagani, the Hazard Team Coordinator, shared, "We have incorporated several new models contributed from our partners including the US, Canada, New Zealand and Japan, and achieved greater homogeneity among independent models. We have also improved the spatial resolution of computed results and added more intensity measure types to the hazard outputs, offering a more comprehensive and detailed assessment." ​ Vitor Silva, the Risk Team Coordinator, highlighted the major updates in the seismic risk model, stating, "Enhancements include major improvements to the global exposure by incorporating new building data due to inflation and population growth, and disaggregating exposure information to a much higher spatial resolution to improve risk estimates, particularly for major urban areas. Building vulnerability estimates have also been updated to reflect local construction practices as well as to incorporate the vulnerability of building contents. Most importantly for humanitarian applications, risk results now include estimates of human mortality, injuries, and displacement." ​ Alongside the global maps update, GEM’s Catalina Yepes, Seismic Risk Engineer will introduce the Earthquake Scenarios Database saying “We have developed a collection of information on the impacts of some of the most important historical earthquakes, including information on the physical and economic impact, as well as records of ground shaking and ground failure. This approach fills an important gap in disaster consequences databases by providing information on hazard and impact that is much needed for verifying models and estimating future event consequences. We are hosted in GitLab, as a free and open resource for global earthquake risk assessment efforts.” ​ What to expect ​ The theme of GEM’s conference “Are we making a difference” provides the platform to showcase these new developments as well as to sample some important applications of GEM’s analysis tools, models and data for risk assessment to inform risk reduction and management decisions. ​ The conference sets off on an impactful note with an introductory session that highlights the invaluable insights gained from the 2023 M7.7 Kahramanmaras-Gaziantep, Turkey Earthquake. This serves as a powerful reminder of the pivotal role of integrating advanced earthquake risk analysis and modeling into comprehensive risk mitigation strategies. The final session will explore the future of earthquake risk assessment science and practice, emphasising innovation and collaboration. ​ Distinguished keynote speakers will share their expertise, including Sinan Akkar, Principal Catastrophe Modeler at Turk Reinsurance Inc., who will discuss lessons from the recent M7.7 Kahramanmaras-Gaziantep earthquake in Turkey. Alanna Simpson, Lead Disaster Risk Management Specialist at the World Bank Group, will present on the landscape of disaster risk reduction initiatives, both past and future. Finally, David Wald, Research Geophysicist at the United States Geological Survey (USGS), will present the case for developing an International Macroseismic Scale. ​ The conference welcomes select attendees in-person by invitation only, while also offering online registration for virtual participation.

Earthquake Risk Modelling a bridge between knowledge and application GEM Impact Story Series Early beginnings: realizing the power of earthquakes to change communities I became interested in earthquakes at an early age. It was 1968, I was living in Istanbul Turkey with my family. We were having dinner when all of a sudden, the ground started to shake and things fell to the floor. It was a time of crisis in Istanbul and what struck me was the earthquake changed everything in just a few seconds. People that were at war were all of a sudden in the streets together and I understood the power of earthquakes to change communities. That memory stuck with me. It has influenced my work as a research scientist and motivated a desire to help people understand what could happen in the event of a disaster. First involvement with GEM, earthquake risk in Canada We know that there's potential for significant earthquakes on the west coast on Canada where I live. I work with the Geological Survey of Canada and was introduced to GEM about five years ago at a hazards and risk modeling workshop in Pavia. One of our mandates as a federal research agency is to generate a national earthquake risk assessment for Canada to help inform disaster risk reduction planning and policy development. GEM and Canada partnership A severe earthquake in any of the known hotspots of Canada would strain existing capacities to respond and recover so understanding both the physical and socio-economic risks at a national scale is a priority for us. We don't have a publicly available seismic risk model right now and there is an urgent need to develop a shared understanding at the level of individual communities. GEM provides a suite of tools and expertise that enable us to do risk assessments at all scales - at the national scale, at the regional scale and at the local scale using an open source set of tools that are available to all. Our partnership with GEM enabled collaboration with academic researchers and partners from other organizations to create a team in Canada that is able now to do more than we could have on our own, So, as we progress in generating our national earthquake risk assessment we continue to learn from GEM and hopefully have something to offer back as well. Earthquake risk modelling as a bridge between knowledge and application GEM for me is a community of researchers who share a passion for telling stories about earthquake risks through the use of analytic models. These risk models are a bridge between our understanding of what could happen in the event of a large earthquake and what we can do about it. And so for me working with GEM is working with people who understand in great detail the various aspects of earthquake risk modeling whether it's the hazard models or the vulnerability models, social vulnerability, earthquake risk - all these pieces need to come together in order for us to understand what could happen in the event of a disaster but most importantly what can we do in advance to reduce our risk to earthquakes in the future. GEM as change agent GEM is a change agent in many ways – the most important are the principles on which it's based- the open collaborative nature of GEM is a game changer I think in the field of earthquake risk modeling. By providing open source tools and providing access to a community of experts worldwide, GEM is really accelerating the way in which we think about and model earthquake risk globally, in a way that we haven't been able to do within the context of individual organizations whether that be a national government organization or a private industry organization. Being part of GEM is like being in a jazz band For me being part of the GEM organization is like playing music in a band. You can play classical music where everyone has a part to play and it's scripted and you play your instrument on the appointed time or you can play jazz. Research as a creative design process And when you play jazz with fellow musicians or researchers you learn from each other. You listen to what they're doing, you learn from each other in the moment and your music becomes alive - it changes, it evolves very quickly. It inspires me to think about research as a creative design process. GEM is about bringing together the best science and the best people to advance the best research possible. Supporting GEM means more efficient international collaboration GEM is a nonprofit organization and it offers an invitation for public sector and private sector partners to join an international collaboration to improve our understanding of earthquake risk modeling and ultimately to understand risk better. The incentive for us in Canada to become a member of GEM is pretty simple. The value proposition is very clear. It allows us to do things that we could not do alone as an individual organization and I think many organizations are in a similar position these days. We're all experiencing reduced funding for our research programs, reduced capacities to do the work that we're asked to do. In collaboration however, we have the potential to do this work more effectively. What GEM offers for us is a network of researchers who bring capacity beyond what we have within our own walls to do the work in a way that we couldn't have done otherwise. GEM as a platform for understanding multi-hazard risk in the future I think the value of being a public sector member of GEM is the opportunity to work together as part of a team – and to think about where this collaboration can go in the future. The communities that we work with certainly experience earthquake risk but they also face other hazards of concern: floods, debris flows, other kinds of hazards. And the work that GEM is doing is leading the way I think toward how we as organizations can think about multi hazard risk in a coherent way and use the tools and platform that GEM has assembled over the last 10 years to take us into the future. About the GEM Impact Stories Earthquake risk remains abstract and highly technical, and there are significant risks that due to poor or limited understanding of it, policymakers and the public at large may not be able to fully take advantage of existing and future information that can either help create better or enhance existing earthquake risk reduction and management strategies, especially at the local and national level. Specifically, the GEM Impact Stories project aims to: Collect and document stories where GEM or its partners have contributed to positive change; Encourage policy and decision makers to use science- and evidence- based information to formulate earthquake DRR strategy at the national level through positive stories of change; and Increase awareness of the public at large on earthquake risk and preparedness.
