News GEM: helping reduce earthquake infrastructure damage through science #BuildToLast By: Oct 7, 2019 Share Facebook LinkedIn Earthquakes are the number one cause of fatalities due to natural hazards from 1998-2017 -- with the majority caused by the 2004 Indian Ocean and 2010 Haiti earthquakes -- and the number two cause in terms of economic losses, second only to storms. (CRED-UNISDR 2018) During that period, earthquakes caused more than half (56%) of the 1.3 million fatalities and cost USD 661 billion or 23% of the USD 2.9 trillion reported economic losses. (CRED-UNISDR 2018) Majority of the fatalities and injuries from earthquakes are due to building collapse attributed to poorly constructed buildings, lack of adherence to land-use zoning and building codes. The limited knowledge and understanding of citizens regarding the risks and mitigation measures around disasters could have also contributed to less demand for accountability. (Why Do People Die in Earthquakes? - Kenny, 2009) We cannot build a sustainable future with these monumental numbers. But as daunting as they might seem, they are not insurmountable and solutions are available. What can we do to address this? This year’s International Day for DRR theme is ‘Build to Last’, which is Target D of the Sendai Framework: to reduce disaster damage to critical infrastructure and disruption of basic services. GEM believes that by better understanding earthquake risk, and developing the capacity of disaster risk reduction stakeholders, we can significantly reduce fatalities, injuries and economic losses from disaster damage through open risk data sharing; the use and promotion of transparent risk assessment tools; adherence to scientific methodologies; inclusiveness and participation; and putting the interest of the public to the fore. John Schneider, GEM Secretary General explains, “Earthquakes might be few and far in between, but when they strike the consequences are of epic proportions.” He adds that since 2009, GEM has been at the forefront of developing open analysis tools, global databases, models at various scales, and capacities of DRR scholars and practitioners to combat the damaging effects of earthquakes to human lives, infrastructure and economy. The importance of understanding seismic hazard The first global seismic hazard model was created within the Global Seismic Hazard Assessment Program (GSHAP) at the end of the 1990's (Giardini et al., 1999). It represented a substantial improvement in our understanding of earthquake hazard globally and offered essential information for the design of buildings and land-use planning to many countries. (GAR, 2019) Almost twenty years later, GEM in collaboration with several organisations and projects released a new compilation of probabilistic seismic hazard models called the GEM earthquake hazard mosaic of earthquake hazard models created either at national or regional (i.e. continental) scale. (GAR, 2019) Marco Pagani, GEM Hazard Team Coordinator explains how GEM’s Global Earthquake Hazard model can be used to help improve resilience to earthquakes. “Many of the models contained in this collection are already used at national level to update building codes and compute risk at national level. Overall, this compilation of models provides a summary of the best science currently applied to the assessment of seismic hazard across the world at national and regional levels.” The importance of understanding seismic risk The calculation of earthquake risk requires a robust earthquake hazard model that defines where, how often and how severely earthquakes will strike in the future; an exposure model (building stock); and vulnerability and fragility functions (likelihood of damage to buildings). Vitor Silva, GEM Risk Team Coordinator says, "GEM’s Global Earthquake Risk model can be used to support decision-makers in the identification of regions that are prone to higher and more frequent earthquake-induced hazards and losses, to distinguish construction types that have high vulnerability, and to devise strategies for effective risk mitigation." To further complicate the problem, in terms of risk reduction, earthquakes pose a particular set of problems for countries in seismically active areas. ‘Return periods’ are long and unpredictable, so low mortality in the recent past is not an indicator of future earthquake risk. (Economic Losses, Poverty and Disasters 1998-2017 - CRED-UNISDR, 2018) A sustainable future This is the reason why risk-informed development planning in earthquake-prone areas cannot be overemphasized. The unpredictability of earthquakes combined with their damaging and deadly effects hinder sustainable development, creation of jobs and availability of funds for poverty reduction initiatives. Understanding risk is a prerequisite for a sustainable future. Mami Mizutori, UN Special Representative of the Secretary General for Disaster Risk Reduction says, “If it’s not risk informed, it’s not sustainable; and if it’s not sustainable it has a human cost.” To help achieve this year’s DRR Day theme, GEM has compiled in the Related Content sidebar several links to GEM’s products useful for developing disaster risk reduction management strategies.

Publications Probabilistic Seismic Risk Assessment for Costa Rica Share Facebook LinkedIn Download 2018 | Peer-reviewed This study presents a seismic vulnerability and risk assessment of the residential building stock in Costa Rica. It proposes a new exposure model using housing census data, public construction statistics, and private construction information to quantify and characterize the residential building portfolio. A complete vulnerability catalogue is established by developing fragility functions for the most common building classes and combining them with existing models derived for risk assessment in South America. An existing probabilistic seismic hazard model was implemented within the OpenQuake-engine, and complemented with a simplified site model to account for site effects. Earthquake risk assessment is achieved by means of a probabilistic event-based analysis, which allowed the estimation of several risk metrics. These include average annualized losses at a national scale, disaggregated per building class and administrative regions. The probable maximum losses and exceedance probability curves were generated using a stochastic event set with 100,000 years of events per logic tree branch.

News GEM Launches Enhanced Building Taxonomy Tools By: Jul 7, 2025 Jun 26, 2025 Share Facebook LinkedIn On 26 June, GEM unveiled its revamped Building Taxonomy tools, providing open-access scripts to support the classification of global building stocks as part of seismic risk analysis. The launch was presented during the Board meeting by Catalina Yepes, GEM’s Exposure Development Lead, and Matteo Nastasi, Senior Software Developer. The GEM Building Taxonomy establishes a consistent framework for describing buildings worldwide using 13 key attributes – such as structural system, construction material, building height, roof type and foundation. Originally published in 2013, Version 2.0 introduced these core attributes to ensure relevance, simplicity and extensibility. The latest Version 3.3, now available on the GitHub-hosted site, retains this foundational structure while incorporating improved data table and links to tools such as the taxonomy validator and explanator, available both via a User Interface and a Python package. The Building Taxonomy supports GEM’s mission to make risk modelling open, interoperable, and globally adoptable. It serves a wide audience – from engineers and planners to insurers and researchers – by providing a reliable framework to catalogue buildings consistently for exposure and vulnerability assessment. GEM encourages users to explore the tools, contribute images or examples to the glossary (which will soon be updated to Version 3.3), and join efforts to expand the taxonomy, ensuring the tool remains adaptable to emerging building types, hazards, and research needs.
