- D.2.1. A framework for seismic hazard assessment in the GR-TR CBA
Summary: Harmonized Framework for Seismic Hazard Assessment. Deliverable D.2.1 establishes a framework for data exchange and collaborative seismic hazard modeling. It introduces a logic-tree approach to manage uncertainties in seismic source models and ground motion predictions and emphasizes the use of software adhering to current standards for Probabilistic and Deterministic Seismic Hazard Analyses (PSHA & DSHA). Four pilot sites — Alexandroupoli, Canakkale, Izmir, and Vathy— are defined to represent the region’s seismic characteristics.
- D.2.2. Joint assessment of seismic hazard in the pilot sites of the Greece-Türkiye CBA
Summary: Probabilistic and Deterministic Seismic Hazard Assessment (PSHA & DSHA). Deliverable D.2.2 presents localized and regional seismic hazard maps for key intensity parameters such as Peak Ground Acceleration (PGA) and spectral accelerations at various natural periods. The findings highlight high seismic hazard areas. The results underscore the importance of integrating multiple source models to address epistemic uncertainties.
- D.3.1. A framework for data & information exchange for seismic risk harmonization in the GR-TR CBA
- D.3.2. Joint Seismic Risk Assessment of School Buildings
Summary: Seismic Risk Assessment for Educational Infrastructure. Deliverables D.3.1 and D.3.2 focus on evaluating the seismic vulnerability of school buildings in the CBA in a harmonized manner. Using fragility curve datasets related to the structural characteristics of school buildings that were derived from census data and Rapid Visual Screening (RVS) methods, the studies assess construction types, seismic code levels, and building heights. The findings provide local authorities with actionable insights for risk mapping and decision-making, particularly in Alexandroupoli Samos, Canakkale, and Izmir.
- D.4.1. Joint investigation of seismic risk indicators based on instrumentation of school
Summary: Real-Time Seismic Monitoring and Damage Assessment. Deliverable D.4.1 emphasizes the importance of monitoring school buildings to assess their seismic response. Using low-cost accelerometers and real-time data analysis, it highlights methods for rapid prediction of structural damage, such as inter-story drift and stiffness degradation. These findings enhance seismic preparedness and provide tools for rapid post-earthquake assessments.
Ιmpact and “Future Directions
The EReS project delivers critical advancements in seismic hazard and risk assessment for the Greece-Türkiye CBA, fostering collaboration and data sharing through platforms like the REDA system. By harmonizing methodologies and focusing on vulnerable infrastructures such as schools, the project enhances the region’s resilience to seismic events. Future work should continue integrating real-time monitoring systems and refining risk assessment models to further support local authorities in earthquake preparedness and mitigation efforts.
