Projects CCARA Caribbean and Central America Earthquake Risk Assessment (CCARA) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background Earthquake risk is on the rise and earthquakes are expected to take an increasing number of lives. Hazard and risk assessments are the foundation for raising awareness among policy makers and the general public, forming the basis for decisions and actions that effectively build resilience and can reduce risk. While important work has been carried out in the Central American and Caribbean region to understand earthquake risk assessment and management there is still ample room to enhance that understanding and properly introduce it in decision- and policy-making processes. In many areas of the world, state-of-the-art information and tools to assess earthquake risk have been inaccessible for a long time. As a first step to tackle this problem, the Global Earthquake Model (GEM) has been created and spent the past 11 years collaboratively advancing open source science and technology for global state-of-the-art seismic hazard and risk modeling, data collection, and risk assessment at scales from local to national, regional, and global. Objectives The project aims to calculate hazard and risk, and to estimate the compounding social and economic factors that increase the physical damage and decrease the post-event capacities of populations to respond to and recover from damaging earthquake events in The Caribbean and Central America, by involving local experts from throughout the region. The goal of the Program in Central America and the Caribbean is to develop capacity in the region for earthquake risk assessment by leveraging GEM tools and resources, to enhance the understanding of earthquake risk, and to bridge the gap between risk assessment and disaster risk reduction. To improve the understanding of earthquake risk in the Central America and Caribbean region while developing local capacities to use open source resources for producing earthquake hazard and risk information at regional, national and local scales. To engage with decision-makers and other end-users to make the connection between advanced risk assessment by local experts and risk-reducing action and so influence DRR policy. Collaborators The CCARA project would not have been possible without the contributions of all the municipalities in particular: the Municipality of San José (Costa Rica), National Commission of Emergencies (CNE), University of Costa Rica (UCR) - Laboratorio Nacional de Materiales y Estructuras (LANAMME), INETER, ONESVIE, ODPEM, BRGM, Bureau des Mines, VT, Geologica UPR Mayaquez, UNI, SRC and UMG.

The project is led and coordinated by EPOS ERIC with funding support from the European Union (EU) under the Horizon Europe program, and will be implemented across various geographic locations within Europe and may extend its partnerships to other regions globally. Duration: September 1, 2024 to August 31, 2024 More details: https://www.epos-eu.org/on . Expected Key Outputs GEM work packages (WP) include scientific products that support risk management: WP3 Contribution to Tackle Societal Challenges - Enhancement of existing EPOS services for improved risk management for natural hazards, supported by dialogue with the EU Union Civil Protection Knowledge Network (UCPKN). Data products and services for rapid post-event assessment: this includes the improvement of existing tools (e.g., European ShakeMap service) for rapid post-event assessment of earthquake impacts and associated secondary hazards (e.g. liquefaction), tools to predict population dynamics in the immediate aftermath of a disaster, and databases of damage-dependent seismic vulnerability models for European buildings. WP5 Enlarging European and International Collaborations - Establishment of collaborative partnerships with relevant research infrastructures to promote synergies and expand global access to EPOS services and data. Support for the expansion of the existing European seismic risk services to include maps representing the environmental impact associated with earthquakes in terms of equivalent carbon dioxide (eCO2) emissions arising from damage and subsequent repair activities.

Projects SSAHARA Project Sub Saharan Hazard and Risk Assessment (SSAHARA) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background The East African Rift System (EARS) is the major active tectonic feature of the Sub-Saharan Africa (SSA) region. Although the seismicity level of such a divergent plate boundary can be described as moderate, several damaging earthquakes have been reported in historical times, and the seismic risk is exacerbated by the high vulnerability of the local buildings and structures. Formulation and enforcement of national seismic codes is therefore an essential risk mitigation strategy. A reliable risk assessment must be based on an updated and reliable seismic hazard model for the region. The last published regional model for SSA was developed within the frame of the GSHAP project and is almost 20 years old (Midzi et al., 1999). The availability of new data, local and regional seismotectonic studies and recently developed methods and tools prompt the development of a new PSHA model summarizing the current state of knowledge in Sub-Saharan Africa. Objectives In September 2014, the United States Agency for International Development (USAID) GEM funding support to implement a program entitled “Reducing Earthquake Risk collaboratively by Building Capacity and Leveraging GEM’s Open Tools and Resources”. One of the objectives of this program was: to build the capacity in sub-Saharan Africa for integrated risk assessment and development of city earthquake scenarios involving local decision-makers. The project produced the SSA-GEM homogenized catalogue; the Seismic Source Zones; the Probabilistic Hazard Calculations; the Strain Rate Model; earthquake risk in East Sub-Saharan Africa; the residential building stock; and the Social Vulnerability and Integrated Risk in Sub Sahara Africa. Collaborators The development of a regional model would not have been possible without the contribution of experts from the local scientific community. Partnership with local governmental institutions and authorities was an essential step to facilitate model acceptance and for potential integration with national seismic codes. GEM worked with the following institutions for the implementation of the SSAHARA project.

Projects PAPERS Piattaforma Analisi Pericolosità E Rischio Sismico Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The Global Earthquake Model (GEM) Foundation has launched the PAPERS project (Piattaforma Analisi Pericolosità E Rischio Sismico), an initiative aimed at developing a new WebGIS platform for scenario hazard and risk assessment in Italy. The project has been funded as one of the cascade grants launched by the High-Performance Computing, Big Data e Quantum Computing Research Centre, one of the five National Centres established by the Italian National Recovery and Resilience Plan (NRRP), under Spoke 5 - Environment and Natural Disasters . The first training workshop of the project related to the use of the OpenQuake engine was successfully conducted online on April 1st, 2025, marking the first in a series of planned training events. This first workshop also served for exploring potential third-party contributions to models that could be integrated into the platform. Objectives PAPERS will enhance seismic risk assessment in Italy through advanced computational techniques and open-source models and tools. The project is organised into three modules, each focusing on a critical objective. The first module involves building the operational platform, leveraging the OpenQuake (OQ) Engine. The integration of High-Performance Computing (HPC) will facilitate complex analyses, while interoperability with external software will streamline data management. The second module focuses on updating Italy’s national exposure models. This involves compiling databases of buildings, critical infrastructure, and distributed networks at different geographic scales in the country. The project will integrate existing models with newly available datasets. This effort will provide a more comprehensive understanding of the seismic vulnerability of the Italian-built environment. As part of the third module, the platform will feature preloaded models of seismic hazard, exposure, and vulnerability, along with a range of earthquake scenarios, including historical earthquakes and events from a stochastic catalog based on the 2020 European Seismic Hazard Model (ESHM20). Alternative risk mitigation strategies will also be explored through dedicated multi-criteria decision-making approaches.
