A classification scheme for the vulnerability attributes of buildings Products GEM Building Taxonomy A classification scheme for the vulnerability attributes of buildings Share Facebook LinkedIn Description The GEM Building Taxonomy is a uniform classification scheme - a method to describe and categorise buildings in the same way across the globe as a key step towards assessing their vulnerability and risk. The current version (v4.0.1) has been used in the development of the v2026 Global Exposure Model. A tool has been developed to help users to quickly validate and understand the classification of buildings according to the GEM Building Taxonomy. It ensures that buildings are correctly categorised, providing explanations for each classification and helping users meet global standards in building classification.

Repository with the inventory of residential, commercial and industrial buildings in Oceania Products Oceania Exposure Repository with the inventory of residential, commercial and industrial buildings in Oceania Share Facebook LinkedIn Description The Global Exposure Model is a mosaic of local and regional models with information regarding the residential, commercial, and industrial building stock at the smallest available administrative division of each country and includes details about the number of buildings, number of occupants, vulnerability characteristics, average built-up area, and average replacement cost. The dataset is developed and maintained by the GEM Foundation, using a bottom-up approach at the global scale, using national statistics, socio-economic data, and local datasets. This model allows the identification of the most common types of construction worldwide, regions with large fractions of informal construction, and areas prone to natural disasters with a high concentration of population and building stock. The Oceania region of the model includes the information pertaining to the following countries/territories: American_Samoa, Australia, Cook_Islands, Fiji, Guam, Kiribati, Marshall_Islands, Micronesia, Nauru, New_Caledonia, New_Zealand, Niue, Northern_Mariana_Islands, Palau, Papua_New_Guinea, Samoa, Solomon_Islands, Tonga, Tuvalu, Vanuatu For the cases of Australia and New Zealand, the exposure model is built upon datasets obtained with collaboration from our partnerships with Geoscience Australia and GNS Science New Zealand.

One of the first steps towards this objective has been the open-source development and release of software for seismic hazard and risk assessment called the OpenQuake Engine. This software comprises a set of calculators capable of computing human or economic losses for a collection of assets, caused by a given scenario event, or by considering the probability of all possible events that might happen within a region within a certain time span. Since its initial release in 2010, the OpenQuake engine remains as one of the most important products released by the GEM Foundation, and it has become the benchmark software for seismic hazard and risk calculations worldwide.

OpenQuake engine input model to perform hazard calculations for South Africa Products South Africa Hazard OpenQuake engine input model to perform hazard calculations for South Africa Share Facebook LinkedIn Description The initial version of the model was developed by scientists from the Council for Geoscience, South Africa and the Indian Institute of Technology, Jammu, India. The model is described by Midzi et al. (2019). The seismic source model was developed using a newly updated catalogue and consists of zones of distributed seismicity, while the ground motion logic tree consists of two existing ground motion prediction equations (GMPEs) derived for active shallow crust. The model was originally created for the OpenQuake engine. Since the original version, several updates were made to the model by the GEM hazard team, leading to the latest release (v2018.2.0), which was used in the computation of the 2026 Global Earthquake Hazard and Risk Maps. Among other important improvements, this model extends the minimum magnitude of events for crustal distributed seismicity and updated the GMPEs used for more recent ones.

A global homogenised catalogue of earthquake events from 1900 to 2024 Products Global homogenised earthquake catalogue A global homogenised catalogue of earthquake events from 1900 to 2024 Share Facebook LinkedIn Description The 2026 GEM Global Homogenised Earthquake Catalogue contains ~495 000 events between 1900 and 2024. The catalogue combines events above M4 from three global datasets: ISC-GEM (https://www.isc.ac.uk/iscgem/, currently v11.0), the Global Centroid-Moment-Tensor (https://www.globalcmt.org/) and comcat (https://earthquake.usgs.gov/data/comcat/) catalogues. To provide a single consistent magnitude type for PSHA, all events are homogenised to moment magnitude (Mw). Magnitude uncertainties from the original catalogues are propagated including uncertainties associated with any magnitude conversions. Where available, focal mechanism data, depth, magnitude and location uncertainties are retained. Original magnitude types and values from contributing catalogues are also included to help track event origins consistently. How to cite this work Bayliss, K. and Pagani M. (2026).

In 2004, during the 11th OECD-GFS Meeting, realizing the lack of venue to discuss earthquake science, the German delegation proposed to hold a workshop to discuss the issue. OUR HISTORY In 2004, during the 11th OECD-GFS Meeting, realising the lack of a venue to discuss earthquake science, the German delegation proposed to hold a workshop to discuss the issue. Over the next two years, a series of workshops and meetings culminated in the identification of a need to create a Global Earthquake Risk Mapping and Monitoring Programme or GEM in 2006. GEM’s financial feasibility received a critical boost in 2007 after MunichRe agreed to become its first and main private participant through a 5M Euro contribution for a period of five years. In the succeeding year, the OECD Global Science Forum selected EUCENTRE in Pavia, Italy as the host institution for the GEM Secretariat. Following two significant milestones, the GEM Foundation was incorporated in Pavia, Italy as a non-profit organization in 2009, giving the Foundation a legal identity with a vision of a world that is resilient to earthquakes.
