Abstract:
|
We present a method for estimating earthquake time dependence in probabilistic seismic hazard analysis; this method uses the fault‐slip rate and available information about the amount of time that has elapsed since the most recent event (tMRE). We call this estimate the Equivalent Poisson Hazard Ratio (EPHR) because it adjusts the corresponding time‐independent (Poisson) hazard estimate. Other inputs include generalized distributions for the possible average displacement per event and the recurrence model coefficient of variation. Lognormal, Brownian passage time, and Weibull time‐dependent recurrence models are considered. We illustrate the method with two faults that are located on the central California coast. One of these faults, the Hosgri fault, slips at a nominal rate of 1.7
