  • CCARA | Global Earthquake Model Foundation

    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.

  • METIS | Global Earthquake Model Foundation

    Projects METIS Methods and Tools Innovation for Seismic Risk Assessment Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background GEM is set to start a 3-year project called METIS or Methods and Tools Innovation for Seismic Risk Assessment funded by the European Commission. The project is part of the Safety margins determination for design basis-exceeding external hazards program. Electricite De France (EDF), a GEM technical collaborator, is coordinating the project which will be implemented in collaboration with 14 other organizations. GEM will contribute to the task on seismic hazard assessment and on PSA Tools and Methodology. In the hazard task, GEM will implement into the OQ Engine methods such as vector-valued probabilistic seismic hazard analysis (PSHA), cluster-based PSHA as well as new methods to propagate epistemic uncertainties. Research will also be carried out in the context of processing earthquake catalogues to remove aftershocks and foreshocks and on testing PSHA models. GEM’s contribution to the PSA Tools and Methodology will concentrate on testing risk results. Duration: 2020 - 2025 More details: https://metis-h2020.eu/ Objectives The objective of METIS is to translate research into practice through rigorous and efficient methodologies and tools to assess seismic safety of NPP (nuclear power plants). It also aims to innovate current practice by combining simulation with experimental data. The research will develop methods to improve the ability to define safety limits for extremely rare events, which go beyond current design analyses (i.e. design extension for earthquakes). The refined seismic PSA (probabilistic safety assessment) is expected to provide meaningful support in defining regulations for safe design of NPP, as well as for assessing plant safety in real-time in case of temporary unavailability of relevant safety equipment or structures.

  • SOLOMON ISLANDS EXPOSURE | Global Earthquake Model Foundation

    Projects SOLOMON ISLANDS EXPOSURE Assessing the Risk Exposure of Road Network to Climate and Natural Hazard Risks in Solomon Islands Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background This project aims to conduct a robust multi-hazard risk assessment of the road network to climate and natural hazards in the Solomon Islands, both historically and under future climate projections. The project includes three main dimensions: - Characterization of the climate and natural hazards - Physical vulnerability of the road network - Multi-criteria criticality analysis The three main outputs are: - Multi-hazard maps - Road network risk exposure analysis (global risk score) - Identification of "first priority" road segments and estimation of their rehabilitation costs The GEM Hazard Team supports the project by computing seismic hazard maps and uses these to produce maps to classify low to high risks of earthquake hazards, according to their intensity and frequency. Duration: 2021 Objectives Many Small Island Developing States (SIDS) share a major common feature: they are among the most exposed nations to natural hazards and climate change. SIDS are also characterized by insularity and geographic remoteness, as well as small geographic area, economies, and population, all of which increase their social and economic vulnerability. This project aims to assist the Solomon Islands to better manage climate and disaster risks by improving the understanding of risk and the use of this information for risk reduction decision-making, and the design and implementation of investments at the provincial and community level.

  • CRAVE | Global Earthquake Model Foundation

    Projects CRAVE Collaborative Risk Assessment for Volcanoes and Earthquakes (CRAVE) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Summary The need to better understand the existing earthquake and volcano risk led to the establishment of the Global Earthquake Model (GEM) and the Global Volcano Model (GVM) network. GEM, founded in Italy in 2009, has been developing open tools and models to calculate and communicate seismic hazard and risk worldwide. Similarly, the GVM network represents an international community aiming to provide systematic evidence, data and analysis of volcanic hazards and risk on national, regional and global scales working with monitoring institutions to implement the best science and DRR strategies. Both GEM and the GVM network are currently leading international efforts that aim to mitigate the adverse effects from these perils. South America and ASEAN regions have been the target of numerous studies in the last two decades. However, most of these studies only focused on one component of the risk problem (e.g. hazard, vulnerability). Such limitation prevents the development of a comprehensive risk profile to properly inform decision-makers. The CRAVE project, through the current GEM and GVM network tools will offer a timely and unique opportunity to advance the understanding of seismic and volcanic risk in the region. Objectives This project aims to develop a common framework for the assessment of the impact from earthquakes and volcanoes, with an application in three countries located around the Pacific Rim. The activities comprised in this project feature several events to bring together global partners with the mandate to calculate and communicate seismic and volcanic risk, as well as training events to increase the capacity of local institutions in the assessment of their hazard and risk. Collaborators This project includes several partners including the following: British Geological Survey; the Earth Observatory of Singapore (EOS); the University of Edinburgh; the Volcano Disaster Assistance Program (VDAP) of the United States Geological Survey (USGS); and key organizations from the region including: the Colombian Geological Survey; the Philippine Institute of Volcanology and Seismology;(PHIVOLCS); and Badan Geologi (Indonesia). Location Colombia, Indonesia and the Philippines Volcano Scenario tool for OpenQuake The CRAVE project required the implementation of a new calculator in the OpenQuake Engine called ‘multi_risk’, which is able to manage at the same time different types of hazards, specifically ash fall, pyroclastic density currents flow, lava flow and lahar flow, passed as CSV files with headers ‘lon’, ‘lat’, ‘intensity’. The calculator is also able to consider the difference between dry and wet ash by setting the `ash_wet_amplification_factor` parameter in the job.ini file. The output of the calculator is a CSV file with ‘Exposure + Risk’ fields. For convenience we also produced a ‘Total Risk’ output which is simply the sum over the assets of the values in the ‘Exposure + Risk’ output. In order to support other formats used in the volcanic hazard community we prepared tools to convert hazard footprints into the format accepted by the OpenQuake-engine. These tools were included in the Input Preparation Toolkit. [Software ] Volcano Model example Full example of the volcano model developed with the Servicio Geológico Colombiano (SGC).

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.

  • HORUS | Global Earthquake Model Foundation

    Projects HORUS Horus: Pilot for a generic damage evaluation methodology based on remote-sensing data Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background Horus is a pilot project that explores the combination of high-resolution building inventory data from OpenStreetMap and other local sources with image-processing algorithms for the detection of earthquake damage and flood extents using remote-sensing data, along with supplementary geospatial datasets as inputs to a machine learning (ML) classification model. The ML model is trained using detailed building damage datasets from past events in a supervised learning framework, and the trained model is intended to be used to estimate the extent of damage and loss in events previously unseen by the model. The proposed framework is applied in three case study applications: March 2020 Mw5.3 Zagreb earthquake; January 2020 Mw6.4 Puerto Rico earthquake and August 2016 Louisiana floods. The GEM Risk Team is responsible for the overall coordination of the project involving multiple partners, compilation of building-level earthquake damage datasets, development of the ML models, and training and testing of the models. Duration: 2020 Objectives This pilot project, initiated and funded by the World Bank, aims to develop a framework for semi-automated damage and loss assessment due to earthquake and floods from Earth Observation (EO) data and other supplementary datasets, while also leveraging recent advances in machine-learning algorithms. These damage and loss estimates can potentially be used for transparent financial compensation and to target the distribution of resources geographically and temporally.
