oct ۱۸th discussion … decision time for nshmp possible predicaments suggested steps forward review logic tree options evaluation criteria decision time for nshmp present situation possibilities ucerf۳ is reviewed in short order and everyone is happy with methodology and results ucerf۳ is deemed technically flawed and not fixable in time for ۲ ۱۴ nshm. given complexity there is not enough time for adequate review vetting of ucerf۳ for nshm ucerf۳ is found to be technically sound with inevitable adjustments but mean hazard changes are up to factors of ۱ in many areas and only understood to some level of specificity probability ۱ ۲ ۳ ۵ nshmp options here … decision time for nshmp nshmp options if there is no ucerf۳ do not update ca erf for ۲ ۱۴ nshms only update non fault based sources with alternative regional rates and spatial pdfs do b and add some of the new faults as type b sources bulge will increase using geologic slip rates update everything including type a faults in a ucerf۲ like way issues what exactly is ucerf۲ like who would do this wgcep is already near burnout would be demoralized this could take as long as fixing ucerf۳ given la quila would anyone sign off on amodel that lacks multi fault ruptures decision time for nshmp present situation possibilities ucerf۳ is reviewed in short order and everyone is happy with methodology and results ucerf۳ is deemed technically flawed and not fixable in time for ۲ ۱۴ nshm. given complexity there is not enough time for adequate review vetting of ucerf۳ for nshm ucerf۳ is found to be technically sound with inevitable adjustments but mean hazard changes are up to factors of ۱ in many areas and only understood to some level of specificity probability ۱ ۲ ۳ ۵ given el mayor cucapah mmax darfield christchurch mmax triggering tahoku segmentation m۸.۶ sumatra weird one does anyone believe we know mean hazard within ۱ are we reluctant to put these out because it implies we’ve misled user communities or didn’t push the epistemic uncertainties hard enough is looking at hazard implications before finalizing weights cheating oct ۱۸th discussion … decision time for nshmp possible predicaments suggested steps forward review logic tree options evaluation criteria the wgcep path forward the only one in my opinion wrap it up finish and publish asap in part to satisfy contractual obligation to cea let others decide what to use in ۲ ۱۴ nshms e.g. some weighted average of old and new hazard curves at each grid node the wgcep path forward the only one in my opinion specific steps get feedback here on final branches weights decide how to handle convergence and equation set weights decide on any a posteriori weighting scheme what to add to morgan’s data fits table finalize calculations document for review by nov ۱st if all goes well activate review hands on aggressive back and forth in terms of answering questions how long will this take finish by year end finalize publish in ۲ ۱۳ oct ۱۸th discussion … decision time for nshmp possible predicaments suggested steps forward review logic tree options evaluation criteria proposed logic tree branches proposed logic tree branches two fault models same number as in ucerf۲ weighted equally proposed logic tree branches four deformation models much broader range than in ucerf۲ off fault moment rates provided ucerf۲ type c zones gone a priori weights represent an average among those of a special review panel proposed logic tree branches scaling relationships only hb ۸ ellb used in ucerf۲ equal a priori weights proposed logic tree branches slip along rupture dsr added boxcar option equal a priori weights weldon et al. ۲ ۷ average of ۱۳ large events characteristic slip proposed logic tree branches total m≥۵ event rate per year inside relm region from felzer appendix l ucerf۲ had single value of ۷.۵ which is at the low end here new best estimate of ۸.۷ represents a ۱۶ increase proposed logic tree branches inversion model fault section nucleation mfd characteristic ucerf۲ constrained if type a in ucerf۲ use ucerf۲ nucleation mfd instead. ucerf۲ type mfd ۱ ۳ gr and ۲ ۳ char gutenberg richter constrained b ۱ proposed logic tree branches inversion model fault section nucleation mfd use only characteristic if gutenberg richter requires reducing slip rates by ~۴ how many would give it a relative weight ۱ proposed logic tree branches mmax off fault ucerf۲ had off fault values of either ۷. or ۷.۶ el mayor cucapah exceeded ۷. so we’ve increased to ۷.۲ at the low end the value of ۸. is new weights are different for char vs gr branches ucerf۲ mmax proposed logic tree branches off fault spatial seis pdf three options with two new ones ucerf۳ smoothed seis deformation model ave ۳ more could be added ۱ for each deformation model weights are different for char vs gr branches exactly how these are used shortly… proposed logic tree branches off fault spatial seis pdf ucerf۲ smoothed seismicity ucerf۳ smoothed seismicity average deformation model log۱ prob for each grid cell values sum to ۱. abm neokinema zeng use deformation model specific off fault spatial pdfs proposed logic tree branches fault moment rate fixes this deals with cases where fault moment rates are too high to satisfy all data currently only an issues for gr branches more on this shortly grand inversion results data fits regional mfds slip rate fits paleo event rate ave slip fits tabulation of equation set fits and other metrics e.g. implied cc implications plots participation rate maps parent section mfds also tabulated correlation between paleo sites implied segmentation e.g. on saf fault jumping statistics slip covs e.g. hecker et al. lots of stuff in scec vdo erf based plots mfds in la and sf boxes hazard curves at sites hazard maps rtgm at sites statewide losses we currently have these and more implemented although we haven’t yet had time to examine everything evaluation metrics mean min and max from all logic tree branches ucerf۳ mean ucerf۳ mean cumulative ucerf۲ …
