On 6 February 2023, two major earthquakes struck southeastern Türkiye along the East Anatolian Fault, causing widespread structural damage, including the partial collapse of the historic Habibi Neccar Mosque in Antakya. This study presents a simulation-based approach to rapidly assess the seismic vulnerability of this partially damaged historic masonry structure. Due to the complexity and urgent condition of such heritage buildings, a simplified finite element (FE) modeling methodology is employed to evaluate structural behavior and support immediate stabilization decisions. Response spectrum analysis is applied to simulate and interpret stress distribution and deformation patterns in both undamaged and damaged states. The simulation results highlight significant tensile stress concentrations exceeding 0.2 MPa at dome–arch joints and vaults—primary indicators of localized failures. Additionally, the analysis reveals increased out-of-plane deformations and the influence of soil amplification in the remaining walls, both of which further compromise the structural integrity of the building. The findings demonstrate that simplified FE simulations can serve as practical and efficient tools for early seismic assessment of historic structures, contributing to rapid decision making, risk mitigation, and cultural heritage preservation in earthquake-prone areas.

The global increase in Marine Protected Areas (MPAs) is driven by international goals, like the Aichi Targets (2010) and the Kunming Global Biodiversity Framework (2023), which aim for 30% of land and sea to be protected by 2030. Despite these ambitious targets, experts agree that numerical goals alone are insufficient to address biodiversity loss and ensure ecosystem functionality. This has sparked significant research on the effective management of MPAs, highlighting the importance of biological, socio-economic, and managerial resilience. Various tools have been developed to support these aspects. However, even in areas with management plans, enforcement, and monitoring, stakeholder involvement in assessment processes is vital to equitable and sustainable management. Using Gökova MPA as a case study, this research evaluated its management over a three-year period by applying an assessment tool previously used by co-managing actors. Findings indicate that assessment results can vary depending on who conducts them, and structural challenges, such as coordination issues among governing bodies and overlapping authorities, further complicate management. These insights have been used to formulate recommendations for policymakers and conservation practitioners, emphasizing that reaching the “30 by 30” target requires not only increased area coverage but also improved management practices that incorporate stakeholder perspectives to achieve sustainable management of natural resources.
