Seismic hazard zoning maps are a relatively simple and transparent consequence of the patterns of historical seismicity. Over time, we have refined our understanding of where and why earthquakes occur in continental interiors, and we have improved our characterization of the resulting ground motions and their probabilities. We have begun to understand the important role of uncertainty in seismic hazard analysis. However, there are still significant shortcomings in our treatment of uncertainty that are particularly pronounced for midplate regions. The same lack of knowledge that causes our uncertainty of the hazard also prevents us from accurately quantifying that uncertainty. Are...
