31.1 Modular systems to characterize earthquake source, shaking
hazard, loss estimation, and product dissemination operated within
the PAGER system.

hypocentral depth, and focal mechanism. These initial parameters aid in
developing additional source constraints, particularly the fault rupture
dimensions, which are requisite in the process of robust shaking estimation
for large earthquakes.
The second module consists of generating a uniform (roughly 1 km
square) grid of shaking hazard estimates using standardized strategies
developed for the USGS ShakeMap system (Wald et al. , 2005). The third
module, which deals with earthquake loss estimation, is the primary focus
of this chapter and will be subsequently discussed in detail. Finally, the
