S03. Seismic Hazard Assessment: Ground Motion, Risk, and Methodologies
Conveners: Mustafa Koçkar (Türkiye), Ayşegül Askan (Türkiye), Altuğ Erberik (Türkiye), H. Cem Yenidoğan (Türkiye), Mehdi Zare (Iran), Aybige Akıncı (Italy)
Earlier earthquake hazard assessments relied on determining the "maximum acceleration" expected in the target zone from the selected "maximum credible earthquake," following standardized procedures based on attenuation laws dependent on earthquake magnitude. This approach, known as force-based seismic design, focused on designing buildings based on estimated earthquake-induced acceleration without considering hazards from long-period ground displacements. However, it is now understood that low-frequency, long-duration seismic surface waves pose significant risks to large structures, especially those with tall footprints, as they can cause resonance effects and amplification, particularly on upper floors. This interaction between ground motion and building attributes ultimately determines seismic performance. Ground motion is influenced by earthquake size, propagation pattern, medium properties, and site effects, with soil amplification beneath the structure's foundation being a critical factor. This section welcomes research on seismic hazard and risk, encompassing seismology and earthquake engineering. The key step to reducing seismic losses from earthquakes worldwide is to identify and study hazards, risk, and damage estimation thoroughly. This session welcomes studies including but not limited to:
a) Regional seismic hazard, risk, and loss estimation approaches
b) Empirical ground motion models and seismic hazard assessment of recorded ground motions of past events
c) Code-based related research to structural vulnerabilities

S10. Enhancing Public Understanding: Education, Outreach, and Communication
Conveners: Paramesh Banerjee (Singapore), Begüm Koca (Türkiye), Rajib Shaw (Japan)
Türkiye has begun the biggest settlement transformation project in its history. The primary motivation for this project is the country’s severe earthquake risk. Two recent devastating earthquakes (Mw 7.7 and 7.6) destroyed even newly constructed buildings and caused extensive loss of life. Türkiye’s cities have major sustainability problems besides earthquake hazards in tectonically active areas. Today, the concept of a “sustainable settlement” has a more perceptible meaning than in the past because the new settlement policy requires precise earthquake hazard estimation and mitigation. UN-Habitat, the United Nations Human Settlements Programme, has adopted the 2016 Habitat III Conference outcome document to offer national and local guidelines on the growth and development of cities through 2036. Given the importance of this topic to global development efforts, recent movements pushing to address sustainable development from an urban perspective have taken place throughout the world. The results of this movement can be seen in the inclusion of a stand-alone goal for cities and urban development in the UN’s 2030 Agenda for Sustainable Development, specifically Sustainable Development Goal (SGD) 11, which is to “make cities and human settlements inclusive, safe, resilient and sustainable.” Seismology can contribute to sustainability in all kinds of human settlements, from single-family houses to large, complex industrial buildings and transportation facilities. A sustainable human habitat requires awareness and public participation. Academic contributions will help in preparing education and outreach programs for public awareness.
This section invites your contributions on how seismology education and outreach programs can contribute to the sustainability of cities and other human settlements.

Conveners: Antonella Peresan (Italy), Fabio Romanelli (Italy), Mohamed EIGabry (Egypt), Wang Guoxin (China), Zhang Yan (China)
In the last quarter of a century, physics-based seismic hazard assessment has attracted wide spreading attention in seismological and engineering communities. The emergence of neo-deterministic seismic hazard assessment (NDSHA) represents a new generation of deterministic seismic hazard evaluation, effectively capturing the tensor nature of strong ground motion using the latest advancements in seismology, data science, and computational technology. NDSHA relies on physical modelling of seismic waves propagation (no need for empirical ground motion prediction equations) from a broad set of plausible seismic sources (not a single scenario earthquake). The obtained results provide the basis for comparative studies, testing and validation by real earthquake cases with data intensive observations, and communicating with engineering and emergency management communities for its application. The research and its application play an important role in the endeavor of disaster risk reduction (DRR). In connection to the ASC-AfSC Preparatory Joint Working Group on Neo-Deterministic Seismic Hazard Assessment (pJWG NDSHA), the focus of the session is on:
