What is Earthquake-Induced Landslide Hazard Assessment?

Earthquake-Induced Landslide Hazard Assessment evaluates the probability and spatial distribution of landslides triggered by seismic shaking using methods like Newmark's displacement analysis and peak ground acceleration correlations.

This subtopic integrates co-seismic landslide inventories with empirical models scaled regionally. Key approaches include Newmark's analysis for permanent displacement prediction and PGA-based susceptibility mapping. Over 600 papers address inventories and modeling, with foundational work in Corominas et al. (2013, 1218 citations) and Xu et al. (2013, 614 citations).

Key Challenges

Why It Matters

Earthquake-induced landslides contribute to 25% of seismic fatalities in mountainous regions, as chains of hazards amplify impacts (Fan et al., 2019, 876 citations). Global assessments from 2004-2016 show thousands of fatal events, underscoring needs for regional hazard mapping (Froude and Petley, 2018, 1912 citations). Quantitative risk analysis at multiple scales guides policy and mitigation, reducing cascading disasters (Corominas et al., 2013, 1218 citations).

Key Research Challenges

Scaling Empirical Models Regionally

Empirical models like Newmark's displacement vary in accuracy across regions due to lithology and topography differences. Sensitivity to scaling issues affects susceptibility maps (Catani et al., 2013, 663 citations). Validation requires extensive co-seismic inventories.

Mapping Large Co-Seismic Inventories

Post-earthquake mapping covers vast areas with hundreds of thousands of landslides, as in the 2008 Wenchuan event (Xu et al., 2013, 614 citations). Remote sensing demands high-resolution data integration. LIDAR enhances detection but requires processing expertise (Jaboyedoff et al., 2010, 1085 citations).

Predicting Cascading Hazard Chains

Earthquakes trigger landslide chains lasting beyond shaking, complicating hazard assessment (Fan et al., 2019, 876 citations). Mechanisms link PGA to multi-hazard impacts. Quantitative risk verification remains challenging across scales (Corominas et al., 2013, 1218 citations).
