The predicted PGV were found to agree with the sparse near-fault observations and the TriNet ShakeMap. This method may be applied in both densely and sparsely instrumented regions. In densely instrumented regions it may provide needed redundancy in the event of telemetry or other failure of the primary realtime strong-motion network. In sparsely instrumented areas it may be the only viable approach to estimate the level of near-fault strong ground motions. Although the software was not automated at the time of the earthquake, it was possible to simulate a realtime application.
Epicenter is denoted by a filled star.
Pure strike-slip source mechanism is assumed. The slip represents total slip that occurred within ten time windows of total duration of 13 seconds. The overlapping portions are outlined with white squares. Ji, C., Wald, D.J., and D. V. Helmberger, Slip history of 1999 Hector Mine, California earthquake, Seism.
