State-of-the-art Use of Simulated Ground Motions to Enhance Urban Seismic Resilience in Turkey

Description: 

Estimation and mitigation of seismic risk in urban regions involve a wide range of stakeholders, including geophysicists and earthquake engineers, urban and economic planners, and insurance companies. Effective risk mitigation requires contributions from multiple disciplines, encompassing seismic hazard assessment, building fragility modeling, seismic loss estimation, and resilience analysis. Strong-motion records constitute a key component of these efforts.

In recent years, in addition to recordings from past events, simulated ground motions have become an increasingly important component of earthquake engineering practice, driven by advances in computational capabilities, earthquake source modeling, and site characterization techniques. Simulated motions enable the assessment of seismic response and resilience of urban regions and distributed infrastructure while accounting for complex source, path, and site effects.

This study presents ongoing research on the use of simulated ground motions for integrated assessment of seismic damage, loss, resilience, and social vulnerability in Turkey. Both historical earthquakes and scenario events are considered. Applications focus on urban regions along the North Anatolian and East Anatolian fault zones, as well as the Aegean Sea region. In addition to current practice, data-related challenges and associated uncertainties are discussed.
