  • SSAHARA Project | Global Earthquake Model Foundation

    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.

  • 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.

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.
