...Yajie Lee, M.EERI; Zhenghui Hui, M.EERI; Siamak Daneshvaran; Farhad Sedaghati; William P Graf, M.EERI The Uniform California Earthquake Rupture Forecast Version 3 (UCERF3) relaxes fault segmentation, allowing multi-segment and multi-fault ruptures through fault-to-fault “jumps,” with lengths up...

...Edward H. Field; Kevin R. Milner; Morgan T. Page; William H. Savran; Nicholas van der Elst Abstract We describe recent improvements to the Third Uniform California Earthquake Rupture Forecast ETAS Model (UCERF3‐ETAS), which continues to represent our most advanced and complete earthquake forecast...

... sequences (UCERF3‐ETAS) in a pseudoprospective sense. For comparison, we include a version of the model without explicit faults more closely mimicking traditional ETAS models (UCERF3‐NoFaults). We evaluate the forecasts with new metrics developed within the Collaboratory for the Study of Earthquake...

...Kevin R. Milner; Edward H. Field; William H. Savran; Morgan T. Page; Thomas H. Jordan Abstract The first Uniform California Earthquake Rupture Forecast, Version 3–epidemic‐type aftershock sequence (UCERF3‐ETAS) aftershock simulations were running on a high‐performance computing cluster within 33...

...Yuehua Zeng ABSTRACT The Uniform California Earthquake Rupture Forecast v.3 (UCERF3) model ( Field et al. , 2014 ) considers epistemic uncertainty in fault‐slip rate via the inclusion of multiple rate models based on geologic and/or geodetic data. However, these slip rates are commonly clustered...

...Morgan T. Page; Nicholas J. van der Elst Abstract Epidemic‐type aftershock sequence (ETAS) catalogs generated from the third Uniform California Earthquake Rupture Forecast (UCERF3) model are unique in that they are the first to combine a complex, fault‐based long‐term forecast with short‐term...

...Edward Field, M. EERI; Keith Porter, M. EERI; Kevin Milner, M. EERI We present a prototype operational loss model based on UCERF3-ETAS, which is the third Uniform California Earthquake Rupture Forecast with an Epidemic Type Aftershock Sequence (ETAS) component. As such, UCERF3-ETAS represents...

... into the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3). UCERF3 is the first model to provide self‐consistent rupture probabilities over forecasting intervals from less than an hour to more than a century, and it is the first capable of evaluating the short‐term hazards that result from...

... for the Third Uniform California Earthquake Rupture Forecast (UCERF3), with the goal being to represent aftershocks, induced seismicity, and otherwise triggered events as a potential basis for operational earthquake forecasting (OEF). Specifically, we add an epidemic‐type aftershock sequence (ETAS) component...

...Glenn Biasi, M. EERI; John G. Anderson, M. EERI We present methods to simplify the use of the Uniform California Earthquake Rupture Forecast 3 (UCERF3) in site-specific seismic hazard analyses. UCERF3 defines the “state-of-practice” for hazard assessments in California and underlies the current...

... Abstract The 2014 Working Group on California Earthquake Probabilities (WGCEP 2014) presents time‐dependent earthquake probabilities for the third Uniform California Earthquake Rupture Forecast (UCERF3). Building on the UCERF3 time‐independent model published previously, renewal models are utilized...

...Morgan T. Page; Edward H. Field; Kevin R. Milner; Peter M. Powers Abstract We present implementation details, testing, and results from a new inversion‐based methodology, known colloquially as the “grand inversion,” developed for the Uniform California Earthquake Rupture Forecast (UCERF3). We...

.... Weldon, II; Yuehua Zeng Abstract The 2014 Working Group on California Earthquake Probabilities (WGCEP14) present the time‐independent component of the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3), which provides authoritative estimates of the magnitude, location, and time‐averaged...

...Edward H. Field; Kevin R. Milner; Nicolas Luco ABSTRACT We use the Third Uniform California Earthquake Rupture Forecast (UCERF3) epidemic‐type aftershock sequence (ETAS) model (UCERF3‐ETAS) to evaluate the effects of declustering and Poisson assumptions on seismic hazard estimates. Although...
