Assessing the earthquake resilience of the built environment and defining earthquake risk mitigation strategies require accounting for earthquake-triggered hazards like, e.g., (inland and underwater) landslides and rockfalls, avalanches, liquefaction, lateral spread. The need for accounting for such secondary earthquake hazards has been widely demonstrated by earthquake case studies worldwide, including the recent earthquake sequences in Nepal (2015), Japan (2011), Chile (2010), New Zealand (2010/11), Haiti (2010), China (2008), Pakistan (2005), among others. For example, for the M 7.6 earthquake in the Kashmir mountains, about 30% of the total number of victims had been due to secondary effects. Even when the urban environment is not directly hit by the aforementioned phenomena, a high risk of deadly impacts still exists, as dramatically experienced by the many climbers killed by avalanches and rockfalls triggered by the recent Nepal (April 2015) and the Sabah, Malaysia (June 2015) earthquakes.

In this session, we welcome recent studies and applications using empirical and mechanical approaches to model and predict the distribution, extent, and impact of earthquake-triggered effects, along with innovative research based on real-time monitoring solutions covering both in-situ measurements and remote sensing. We encourage engineering seismological as well as geomorphological contributions focusing on the modeling of seismic ground motions and failure processes contributing to slope instability. Additionally, studies aiming at either on rapid hazard and loss estimation, response, and recovery operations at local and regional scales or long-term probabilistic assessment of the aforementioned triggered phenomena are also welcome.
