GEM is a non-profit organization dedicated to advancing global earthquake hazard and risk assessment through open data, software, and scientific research. Our goal is to improve earthquake preparedness and resilience worldwide by developing state-of-the-art tools and methodologies.

Founded in 2009, the GEM Foundation brings together experts, institutions, and stakeholders from around the world to create open, transparent, and accessible earthquake risk models. Our work supports:

• Disaster risk reduction
• Insurance and financial sector risk management
• Engineering and infrastructure resilience
• Public policy and decision-making

We believe that open science and collaboration are essential to reducing seismic risk globally.

The OpenQuake Engine is our flagship open-source software for probabilistic seismic hazard and risk assessment. See the pinned oq-engine repository below.

We develop and maintain global, regional, and national-scale earthquake hazard and risk models, providing critical data for informed decision-making. See below our pinned repositories for the GEM Building Taxonomy, the Global Exposure Model, the Global Vulnerability Model, the Global Earthquake Impact Database, and our Country/Territory Risk Profiles. We also maintain a number of scientific tools to help modellers - visit our GEM Science Tools sister repository!

Through workshops, online courses, and collaborative projects, we share, exchange, and develop knowledge with communities and institutions, empowering them to assess and mitigate seismic risk while continuously learning from local expertise and real-world applications.

GEM collaborates with international organizations, universities, and both public and private-sector partners to advance earthquake science and risk reduction.

We welcome contributions from researchers, developers, and anyone passionate about earthquake risk reduction. Here's how you can help:

• Contribute to the OpenQuake Engine – Help improve our open-source software.
• Share Data – Provide seismic hazard and risk/impact data to enhance global models.
• Improve Documentation – Help us make our resources more accessible.
• Spread Awareness – Advocate for earthquake preparedness and mitigation in your community.
• Partner with Us - Learn how to become a partner and support our activities here
