About GEM

GEM at a glance

Watch a 6 min introduction video showing our core objectives and goals, with interviews from a wide selection of organisations and experts, our partners and scientists jointly calling for a collaborative international effort to reduce earthquake risk and to empower risk resilience and risk mitigation worldwide.



Vulnerability to earthquakes is increasing, yet reliable risk assessment tools and data are out of reach in many areas of the world. Also, there are no global standards that allow us to compare approaches for risk analysis, while recent events have taught us that we need to work together globally to understand earthquake behaviour and consequences better.

GEM was created to bridge this critical gap, and hereby support risk awareness and actions that increase resilience.



Through global projects, open-source IT development and collaborations with more than 10 regions, leading experts are collaboratively developing global datasets, best practice, open tools and models for seismic hazard and risk assessment.

Guided by the needs and experiences of governments, companies and citizens at large, they work in continuous interaction with the wider community.

All contributions are being integrated into the web-based OpenQuake Platform that – together with other resources – will be accessible to organisations and individuals from November 2014.  Stakeholders worldwide will be able to calculate, visualise and investigate earthquake risk, capture new data and share findings for joint learning.

The people behind GEM

GEM is all about people, which is reflected in our branding. Thousands of individuals contribute time, effort and knowledge to the effort in various ways; meet many of the community on GEM Nexus.

The non-profit and independent GEM Foundation drives the effort. The GEM Foundation comprises a Governing Board with representatives from governmental agencies and private companies who became a participant and fund the effort. Together with prominent international organisations they guide the initiative. A Scientific Board of renowned experts in their field oversees developments from a scientific/technical point of view. Acting as GEM’s CEO, the Secretary General leads an Executive Committee and an operational secretariat that resides in Pavia, Italy. Learn more about how we are organised.

A Model Facility and Testing & Evaluation Facility are independent bodies within the foundation. The first carries out all software development and the latter tests and validates outcomes. Operations Managers oversee activities in a number of regions of the world.
