Earthquake-triggered Ground Failure: Data, Hazards, Impacts and Model

Landslides and liquefaction triggered by earthquakes are a diverse set of phenomena that can cause widespread and significant impacts during and after earthquake shaking. Advances in our ability to model the initiation, extent, and impacts of ground failure are needed to improve our ability to quantify the magnitude and uncertainty of hazard and risk, as well as predict near-real-time losses for emergency response. Models of earthquake-triggered ground failure should consider the complex spatial-temporal variations (e.g., spatial heterogeneity of material properties, climate change, wildfire, anthropogenic changes to the landscape and groundwater levels) on hazard and risk. However, the complete physics of earthquake-triggered ground failure is often impossible to capture at any scale, and simplified probabilistic, regionalized, and or time-dependent modeling of ground failure, as well as the development of detailed inventory and case-history data, are essential to building practical models of ground failure susceptibility, hazard, and loss. 
 
We welcome all submissions relating to earthquake-triggered ground failure, including but not limited to: regional scale susceptibility and hazard assessment; characterizing uncertainty, or developing ensemble model predictions; studies on the impacts, losses, and risk modeling for coseismic ground failure; new or revised inventories, or case histories, from recent and historic earthquakes; as well as advances in information or communication products for earthquake-triggered ground failure.
