Our Vision

GEM’s collaborative efforts will build a heightened public understanding and awareness of seismic risk, leading to increased earthquake resilience worldwide, as the GEM community:

> shares data, models, and knowledge through the OpenQuake platform

> applies GEM tools and software to inform decision-making for risk mitigation and management

> expands the science and understanding of earthquakes

Through a collaborative effort, involving global scientists and stakeholders, between 2009 and 2013 GEM has already made a significant contribution toward advancing the science and technology needed for global state-of-the-art seismic hazard and risk modelling, data collection, and risk assessment at the global, regional, national and local scale. 

From 2014 onwards, GEM’s focus will shift towards practical implementation, public communication and development of the datasets and tools at a local scale, to increase the applicability of GEM products in the OpenQuake platform for reliable risk mitigation anywhere in the world.

GEM however is unique because of its solid scientific base and we will continue to foster that core and our collaboration with the scientific community to stay abreast and incorporate the latest developments in science and technology to continuously increase the value of the tools and resources.

Our Values

These guiding principles define what GEM is and how we work:


Through our commitment to engaging and collaborating with the scientific community, GEM has earned a degree of credibility that has been strengthened by the alliance of the public and private sectors. Trust is critical for any source of information used for public good. Assessing earthquake risk holistically requires multidisciplinary knowledge – seismology, geotechnical and structural engineering, economics and social science – combined with the latest technology. GEM brings together this diverse scientific community with a common language, whilst keeping discussion and debate alive.

WIDER IMPACT - public good

GEM was founded on the principle of equitable risk information. Bridging gaps – both from science to practice, and from knowledge to action – is what we strive for. Even for deliverables that are, at their root, information, their true purpose is to serve risk reduction. Information is an essential precursor to risk reduction and risk mitigation, but only if it is available to all stakeholders. By creating resources that inspire sponsorship by both public and private sectors, we also benefit a broad range of stakeholders, from non-profit to commercial, bringing a once-scarce resource to all sectors and beneficiaries. By making risk assessment inclusive, despite its complexity, we create a culture of awareness and resilience.


The OpenQuake platform is being designed to allow users to evaluate the impact of any assumption on results, implement alternative data or models, and explicitly account for uncertainty. Accompanying OpenQuake will be extensive, open documentation and user-friendly workflows. Source code of the software and tools is publicly accessible and can be utilised and even extended by GEM stakeholders. Transparency is essential not only to our products, but also our processes and information-sharing. GEM resources include global best practice for all methods and approaches. Community feedback and open debate are the drivers of our continuous improvement.

WORKING TOGETHER - collaborative

GEM is all about people with a passion for contributing to the mitigation of seismic risk. We succeed only by collaborating across sector, geography, and discipline. Academia links up with decision makers, the private sector and international organisations within GEM’s public-private partnership. GEM deliverables are the result of global scientific collaboration, and it is through regional partnerships that the GEM mission and implementation will be fully realised. By providing a common understanding of risk, GEM becomes the critical link in creating successful resilient partnerships between policy makers, the private sector, and scientists.
