A common view of continental intraplate seismicity is that large earthquakes occur in areas where peculiar local conditions favor lower lithospheric strength and/or higher stress concentration compared to typical intraplate settings. Although there are numerous explanations for these local strength reduction and stress increase effects, their application to seismic hazard assessment is limited to the few specific regions for which these explanations were developed. In this paper, I present four general models that can be used to define seismic hazards based on the associated geodynamic frameworks and their implications for earthquake locations, sizes, and recurrence rates. The four models are...
