cant proportion of lost production resulting from electricity outages can be “recaptured” by subsequent overtime work in most sectors).

In the following chapters, the incremental benefits of improved seismic monitoring are discussed in detail. This discussion yields predominantly qualitative benefits, although a lower-bound estimate of the benefits that result from performance-based engineering enhancements is presented in Chapter 6. Why are there not more examples of quantitative benefits, especially given the wide range of potential benefits discussed above? The answer is the lack of certain types of information. Although the committee has argued that a wide array of incremental benefits results from an enhanced seismic network, this argument is forward looking. That is, only over time will these benefits be realized. Just as improved seismic monitoring will provide more critical and basic information to earth scientists and engineers, critical information has to be gathered from future earthquake events and provided to scientists in the behavioral sciences (economics, finance, sociology, political science, psychology, etc.) to fully assess the benefits.
