Dependency Risk Graphs have been proposed as a tool to analyze the cascading failures of Critical Infrastructure (CI) dependency chains. However, dependency chain analysis is not by itself sufficient for developing an efficient risk mitigation strategy, i.e. a strategy that defines which CI nodes should have high priority for the application of mitigation controls, in order to achieve the optim...

The assessment of seismic risk in urban areas with high seismicity is certainly one the most important problems that territorial managers have to face. A reliable evaluation this basis for design both specific improvement interventions and emergency management plans. Inappropriate assessments may provide misleading results induce bad decisions relevant economic social impacts. mainly linked thr...

This study investigated the psychological reactions of survivors of the 512 Wenchuan earthquake in China and the risk factors associated with those reactions. The Impact of Event Scale-Revised (IES-R), Type D Scale-14 (DS14), a self-developed trauma experience questionniare, and a demographic questionnaire were administered to 956 earthquake survivors (389 males and 567 females) in Mianzhu, one...

Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to ...

Operational earthquake forecasting in the Uniform California Earthquake Rupture Forecast, version 3 (UCERF3) model will be implemented using the Epidemic Type Aftershock Sequence (ETAS) model. Parameter values for the ETAS model are determined by fitting that model to the recent instrumental earthquake catalog. A grid search is done, and the loglikelihood is used as a measure of fit to estimate...
