Session Description
This session aims to provide a comprehensive platform for advancing our understanding of earthquake-induced landslides, by connecting empirical evidence, site-specific characteristics, and analytical methodologies to risk assessment practices. The occurrence of large-scale landslides triggered by seismic events continues to pose significant challenges to communities and infrastructure across the globe. Improving the prediction, mapping, and management of coseismic landslide hazards requires interdisciplinary insights and international collaboration.
The main objectives of the session are to:
- Compile and analyze important case histories of landslides triggered by major earthquakes worldwide.
- Investigate site response characteristics including amplification, topographic, and material effects, and their influence on landslide occurrence.
- Compare various approaches for assessing landslide susceptibility and defining triggering thresholds.
- Examine the state-of-the-art methods for estimating landslide displacement and runout.
- Explore methodologies for producing earthquake-induced landslide hazard and risk maps at regional and site-specific scales.
We welcome contributions that address (but are not limited to) the following themes:
- Case Histories of Earthquake-Induced Landslides
– Detailed reports on recent or historic events, including mapping, field investigations, data collection strategies, and analytical insights.
- Site Response Characteristics
– Studies on seismic amplification, topographic and lithologic controls, and their correlation with different types of slope failures.
- Landslide Triggering and Susceptibility Mapping
– Threshold-based approaches, empirical and numerical models, and generation of regional-scale susceptibility maps or site-specific hazard zoning.
- Displacement and Runout Analysis
– Modeling techniques for landslide mobility and predictive tools for estimating runout distances under seismic loading.
- Hazard and Risk Assessment
– Integration of physical, statistical, or probabilistic methods to evaluate coseismic landslide risk and support decision-making.
This session encourages contributions from researchers, practitioners, and policymakers involved in landslide science, seismology, geotechnical engineering, and disaster risk reduction. Interdisciplinary and international perspectives are especially welcome.
