We simulate the performance of the Northern California Seismic System (networks NC, NP and BK) of the California Integrated Seismic Network for the case of a repeat of the 1906 earthquake to assess its ability to produce reliable ShakeMaps. Among the many factors that influence the robustness of the system are reliability of telemetry from individual stations and nodes, as well as of the data center. Even with the correct location and magnitude for the earthquake and with all 160 real time strong motion instruments reporting ground motions, it is still critical to estimate the fault length to produce a usable ShakeMap.
